DESCRIPTION OF THE PREFERRED EMBODIMENTS

(Configuration of Multi-Function Peripheral)

FIG. 1 is a diagram of a configuration of a multi-function peripheral (MFP) showing an embodiment of the present invention.

In FIG. 1, a controller 101 for controlling the multi-function peripheral has a hardware configuration shown in FIG. 3, and has a software (control program) configuration shown in DISK 315 of FIG. 76 as a storage medium. A scanner engine 102 is controlled by the controller 101. Laser beam printer engines (LBP) 103, 104 are controlled by the controller 101. The laser beam printer engine 103 is connected to a finisher 106, so that a plurality of recording media (e.g., paper) outputted from the printer engine can collectively be stapled (Hotchkiss) and processed. The finisher 106 is also controlled by the controller 101. An inkjet printer engine (IJP) 105 can also perform color printing, and is controlled by the controller 101. A network (Ethernet) interface 107 provides the controller 101 with bidirectional communication through the interface. IEEE 1394 interface 108 provides the controller 101 with bidirectional communication through the interface. IEEE 1284 interface 109 provides the controller 101 with bidirectional communication through the interface. A user interface 110 is constituted of LCD display and a keyboard to display information from the controller 101 and to transmit an instruction from a user to the controller 101.

For the multi-function peripheral configured as described above, a selection is made from three physical printers LBP 103 (B/W, with Finisher), LBP 104 (B/W), and IJP 105 (Color) so that print job issuance is enabled. Moreover, a selection is made from four logical (cluster) printers LBP 103+LBP 104, LBP 104+IJP 105, LBP 103+IJP 105, LBP 103+LBP 104+IJP 105 so that the print job issuance is enabled. Furthermore, an automatic selection is made from the seven printers LBP 103, LBP 104, IJP 105, LBP 103+LBP 104, LBP 104+IJP 105, LBP 103+IJP 105, and LBP 103+LBP 104+IJP 105 so that the print job issuance is enabled. Furthermore, IJP is used to constitute a logical printer as a printer which can print only white and black so that the print job issue is enabled.

Moreover, scan job can be issued from the outside, and a color original can be read. Furthermore, a selection is made (automatic selection can also be made) from the scanner and the eight printers LBP 103, LBP 104, IJP 105, LBP 103+LBP 104, LBP 104+IJP 105, LBP 103+IJP 105, LBP 103+LBP 104+IJP 105, and IJP which can print only white and black so that the copy job can be issued. Furthermore, when only the printer IJP is present, color copy job can be issued.

Moreover, font, and form overlay can be used in the print job, upload/download can be realized, and resource management can be performed. Moreover, color profile can be used in the print job, scan job, and copy job, upload/download can be realized, and resource management can be performed. Furthermore, log can automatically be generated inside the apparatus and upload can be realized.

Moreover, all the functions can be used from any interface of Network (Ethernet, TCP/IP), IEEE 1284, and IEEE 1394. Furthermore, each interface is associated with a subaddress, physical/logical devices (printer, scanner, copy) and each resource. By selecting the subaddress, these physical/logical devices and each resource can be selected. To each subaddress of each interface, the job can be issued and download/upload can be instructed at the same time. Moreover, the association of the subaddress with the physical/logical device and the resource can be obtained by inquiring of the apparatus itself. Furthermore, the function can be used via an internal user interface.

Moreover, by inquiring of Supervisor described later through the above-described interface from the outside, the outlines of provided functions (a type of job to be issued, a type of resource to be utilized, and the like), job issuance, subaddresses for use in download/upload of the resources, and detailed information of each function (the maximum number of copy sheets, PDL supporting a finisher type, the number of output BIN to be designated, and the like) can be obtained. By using the above-described information, software (control program) can automatically be formed on the side of Client. However, Client needs to know beforehand only the subaddress for use in the inquiry in each interface. A manager can limit the above-described various functions by the connection form and user.

(Entire System Configuration)

FIG. 2 is a diagram showing a system configuration of the present embodiment. In FIG. 2, numeral 201 denotes the multi-function peripheral (MFP) shown in FIG. 1, and the multi-function peripheral 201 is connected to Client PC 202 to 205 (information processing apparatuses) via a network interface cable 208 (10 BASE-T), IEEE 1394 interface cable 206, and IEEE 1284 interface cable 207, respectively. In each Client PC as shown in FIG. 78, various software (control programs) stored in DISK 6009 described later as the storage medium shown in FIG. 77 are operating. Client PC 202 and 203 connected via Ethernet 208 designate ID address and a port number to connect with the multi-function peripheral 201, and output IP packet data. Client PC 204 connected via IEEE 1394 interface 206 designates a node ID and LUN (logical unit number) to connect with the multi-function peripheral 201, and outputs SBP-2 packet data. Client PC 205 connected via IEEE 1284 interface 207 designates a socket number to connect with the multi-function peripheral 201, and outputs IEEE 1284.4 packet data.

Various programs and data shown in FIG. 76 are stored in DISK 315 (storage medium) such as a hard disk, a floppy disk, and the like, sequentially read into Memory (RAM) 302 if necessary, and executed by CPU 301. The DISK 315 may be detachably attached to MFP 201 or incorporated in MFP 201. Furthermore, the program shown in FIG. 76 may be configured to be downloaded from Client PC 202 to 205 or another MFP via the network interface cable 208 (10 BASE-T), IEEE 1394 interface cable 206, and IEEE 1284 interface cable 207 and stored in DISK 315.

The LCD display 303 and the keyboard 304 constitute the user interface (operating portion) 110 shown in FIG. 1. When CPU 301 writes data to LCD display 303, display is performed. When CPU 301 reads data from the keyboard 304, the instruction from the user is entered.

Moreover, to the bus 313 a network interface connector 305, IEEE 1394 interface connector 306, and IEEE 1284 interface connector 307 are connected, and correspond to the network interface 107, IEEE 1394 interface 108, and IEEE 1284 interface 109 shown in FIG. 1, respectively. Then, Ethernet (10 BASE-T) cable 208, IEEE 1394 cable 206, and IEEE 1284 cable 207 shown in FIG. 2 are connected. When CPU 301 reads or writes data from or to these interfaces, communication is performed using the interfaces.

Furthermore, to the bus 313 connected are Laser Beam Printer Engine 308, Finisher 309, Scanner Engine 310, Laser Beam Printer Engine 311, and Ink Jet Printer Engine 312. These correspond to Laser Beam Printer Engine 103, Finisher 106, Scanner Engine 102, Laser Beam Printer Engine 104, and Ink Jet Printer Engine 105 shown in FIG. 1, respectively. When CPU 301 performs data reading/writing via these engines, engine operations such as printing and scanning are performed and various statuses are obtained. Additionally, Laser Beam Printer Engine 308, Finisher 309, Scanner Engine 310, Laser Beam Printer Engine 311, and Ink Jet Printer Engine 312 are arranged not inside MFP 201, but are arranged as separate peripheral units on the network, and may be controlled by the controller 101 of MFP 201.

(Software Configuration of Controller 101)

FIG. 4 is a diagram showing a software (control program) configuration of DISK 315 in the controller 101, and the software (control program) is executed by CPU 301. In the drawing, solid lines indicate data and control, while dotted lines indicate setting and ability obtaining. A user interface driver 401 controls LCD display 303 and a keyboard 304. A user interface manager (control program) 405 interprets input information entered via UI driver 401 from the user, generates a command packet shown in FIG. 46, and transmits an output to an interpreter (control program) 409. The user interface manager 405 also interprets the command packet entered via the interpreter 409, and performs display on LCD display 303 via UI driver (control program) 401.

A network interface driver (control program) 402 controls the network interface connector 305, and processes a physical layer of network packet (physical packet) by extracting a transport packet from the physical packet and generating the physical packet from the transport packet. A TCP/IP, UDP/IP processing module 406 processes the transport packet outputted from the network interface 402, extracts a command packet, and transmits an output to the interpreter 409. Moreover, the module generates the transport packet from the command packet outputted from the interpreter 409, and transmits an output to the network interface 402.

IEEE 1284 driver (control program) 403 controls the IEEE 1284 interface 307. Numeral 407 denotes a processing module (control program) of IEEE 1284.4. IEEE 1284.4 is a standard of a transport layer mainly for the purpose of being used in IEEE 1284 interface. A processing module (control program) 407 of IEEE 1284.4 processes the transport packet outputted from the IEEE 1284 driver 403 to extract the command packet and transmits an output to the interpreter 409. Moreover, the module generates the transport packet from the command packet outputted from the interpreter 409, and transmits an output to the IEEE 1284 driver 403. IEEE 1394 driver (control program) 404 controls the IEEE 1394 interface 306.

A module (control program) 408 processes SBP (serial bus protocol)-2 which is the transport layer in the IEEE 1394. The SBP-2 processing module 408 processes the transport packet outputted from the IEEE 1394 driver 404 to extract the command packet and transmits an output to the interpreter 409. The module also generates the transport packet from the command packet outputted from the interpreter 409, and transmits an output to the IEEE 1394 driver 404. Numeral 409 denotes a packet interpreter which interprets the command packets transmitted from the transport processors 406, 407, 408 and the user interface manager 405 and generates commands. The packet interpreter 409 also generates the command packet in response to a request from another module (control program). In accordance with a subaddress to service ID table (FIG. 9) of Supervisor (general administration manager) 410, the interpreter 409 processes only the command packet transmitted from the subaddress which is valid, and cancels the command packets transmitted from the other subaddresses.

Supervisor (general administration manager) 410 retains in DISK 315 various data shown in FIG. 7 (attribute table), FIG. 9 (subaddress to service ID table), FIG. 11 (service ID to task type table), FIG. 13 (user authentication table), FIG. 14 (access control table), FIG. 16 (event setting table), and FIG. 17 (event format table), and generally manages an operation of the controller 101. In response to entered command instructions, Supervisor 410 refers to or changes various data retained by itself, various data retained by managers (font manager 413, form overlay manager 414, log manager 415, color profile manager 416, print managers 501 to 509, scan job manager 419 and copy job managers 601 to 608), and various data retained by controllers (printer controllers 510 to 512, scanner controller 420).

For the command packet interpreted by the interpreter 409, in accordance with the user authentication table (FIG. 13) and access control table (FIG. 14) of Supervisor 410 (control program), a security gate 411 limits a command input in such a manner that only the user who possesses a correct right to use can use the multi-function peripheral 201. A dispatcher (control program) 412 distributes the commands transmitted from the interpreter 409 to the resource managers (font manager 413, form overlay manager 414, log manager 415, color profile manager 416) and the job managers (print managers 501 to 509, scan job manager 419 and copy job managers 601 to 608) which are control programs for processing the commands. The font manager 413 manages fonts. The font manager 413 retains data as shown in FIG. 26 (attribute table) and FIG. 28 (FONT table) in DISK 315. The font (stored in DISK 315 or ROM 314) managed by the font manager 413 is transferred to PDL rasterizers 417 and 418, and used during a print job processing.

The form overlay manager 414 manages form overlays. The form overlay manager 414 retains data as shown in FIG. 29 (attribute table) and FIG. 31 (FORM table) in DISK 315. The form overlay (stored in DISK 315 or ROM 314) managed by the form overlay manager 414 is transferred to PDL rasterizers 417 and 418, and used during the print job processing. The log manager 415 manages logs. The log manager 415 retains data as shown in FIG. 32 (attribute table) and FIG. 34 (LOG table) in DISK 315. The log is outputted from each manager, and placed under control of the log manager. An execution log file is stored in RAM 302 or DISK 315 and updated at any time.

The color profile manager 416 manages color profile data for a color scanner or a color printer to perform color matching. The color profile manager 416 retains data as shown in FIG. 37 (attribute table) and FIG. 39 (color profile table) in DISK 315. Color profiles managed by the color profile manager 416 are transferred to the printer controllers (control programs) 510, 511, 512 and the scanner controller (control program) 420, and used during processing of the print job, copy job and scan job. The PDL rasterizer 417 processes document data written in PS (registered trademark) as one type of PDL (page description language), and outputs image data. The PDL rasterizer 418 processes document data written in PCL (registered trademark) as one type of PDL (page description language), and outputs image data. The scan job manager 419 manages the scan job. The scan job manager 419 retains data as shown in FIG. 22 (attribute table) in DISK 315. The scan job manager 419 instructs the scanner controller 420 to execute scanning. The scanner controller 420 controls the scanner engine 310. The scanner controller 420 retains data indicating a function, state and performance of the scanner engine 310 as shown in FIG. 44 (attribute table) in DISK 315. The scan job manager 419 and scanner controller 420 have the data indicating the functions and performances (FIGS. 22 and 44), but the functions shown by these data do not need to be the same. By rewriting the data (FIG. 22) retained by the scan job manager 419 through Supervisor 410, the function can be limited.

The above-described font manager 413, form overlay manager 414, log manager 415, and color profile manager 416 are resource management programs, the scan job manager 419, print job managers 501 to 509, the copy job managers 601 to 608 are logical device (scanner, printer) control programs, and the laser beam printer controllers 510, 511, ink jet printer controller 512, and scanner controller 420 are physical device (printer, scanner) control programs.

(Configuration of Print Job Manager)

FIG. 5 is a diagram which supplements the software (control program) configuration diagram shown in FIG. 4. A dispatcher 412 is the same as the dispatcher 412 shown in FIG. 4, and distributes the command packets to the print job managers (control programs) 501 to 509. The print job managers 501 to 509 manage the print job. Each print job manager has data as shown in FIG. 18 (attribute table) in DISK 315. For each print job manager, a printer controller for use in processing the print job (LBP Controller 510, LBP Controller 511, Ink Jet Controller 512, or an arbitrary combination of the controllers 510, 511, 512) and a print engine connected to the controller are determined, and the type of printer controller (control program) to be used is described in data shown by attribute ID 2001 of FIG. 18. However, only the print job manager 508 has a function of dynamically selecting the print engine for use, and it is described in data (attribute table) of the print job manager 508 that the manager has the function. Each print manager retains the entered print job, and data indicating the type of printer controller and the type of job to be executed by the printer controller as shown in FIG. 20 (job table) and FIG. 21 (job request table) in DISK 315. The printer controllers 510 to 512 control the print engines 308, 311 and 312. The printer controller 510 also controls the finisher 309. Each printer controller has data indicating a function, state and performance of the corresponding printer engine as shown in FIG. 40 (attribute table) in DISK 315. Each controller retains data indicating a state of entered print job as shown in FIG. 42 (job queue table) in DISK 315.

The print job managers 501 to 509 and the printer controllers 510 to 512 have data indicating the functions and performances as shown in FIG. 18 (attribute table) and FIG. 40 (attribute table) in DISK 315. In general the print job manager has a performance equal to a sum of the performances of the controllers for use, and a function corresponding to a common item of the function of each controller. However, some of the functions can be changed by rewriting the data (FIG. 18) of the print job manager through Supervisor 410. For example, since the print job managers 503 and 509 use the same printer controller 512, they can present the same performance and function. However, the data of the print job managers can be set by a setting processing described later in such a manner that the print job manager 503 can perform color printing and the print job manager 509 cannot perform the color printing.

(Configuration of Copy Job Manager)

FIG. 6 is a diagram which supplements the software (control program) configuration diagram shown in FIGS. 4 and 5. A dispatcher 412 is the same as the dispatcher 412 shown in FIG. 4, and distributes the command packets to the copy job managers (control programs) 601 to 608. The copy job managers 601 to 608 manage the copy job. Each copy job manager has data as shown in FIG. 24 (attribute table) in DISK 315. For each copy job manager, a printer controller and a scanner controller for use in processing the copy job and a print engine and a scanner engine connected to the controllers are determined, and the types of printer controller and scanner controller to be used are described in the data (attribute ID 2001) shown in FIG. 24. However, only the copy job manager 608 has a function of dynamically selecting the print engine for use, and it is described in data (attribute ID 2002) of the copy job manager 608 that the manager has the function. Each copy manager holds the entered copy job, and data indicating the type of printer controller or scanner controller and the type of job to be executed by the controller as shown in FIG. 20 (job table) and FIG. 21 (job request table) in DISK 315. The printer controllers 510 to 512 control the print engines, and are the same as those shown in FIG. 5.

(Attribute Table of Supervisor)

FIG. 7 shows data (attribute table) which Supervisor (control program) 410 retains in DISK 315 and manages. This table shows a function outline, connection information, security information, and the like of the multi-function peripheral 201. In the table, each line shows one information unit (record), and the data is constituted as an aggregate of a plurality of records. Each record is constituted of attribute ID 701, type ID 702 and attribute value 703, and indicates an attribute of Supervisor. The attribute ID 701 indicates a type of information, thereby indicating a meaning of the value 703. The attribute ID 701 is unique inside the apparatus, and the same attribute ID indicates the same information type. The type ID 702 indicates a type of data which the value 703 has, and is used in interpreting the value 703. The type ID is univocally determined by the attribute ID and defined uniquely inside the apparatus. In the embodiment, the attribute ID 701 and the type ID 702 are both shown in the attribute table, but by retaining an attribute ID to type ID table as data separated from the attribute table, only the attribute ID and value may be shown in the attribute table. The value 703 indicates an attribute value in accordance with the attribute ID 701.

FIG. 8 is a diagram showing details of attribute ID 701 and type ID 702 of the attribute table of FIG. 7. In the drawing, attribute ID 102 "a list of supported security levels" retains a list of security levels which can be set, among security levels required for issuing operation for Supervisor. The security levels will be described in description of an access control table of FIG. 14. Attribute 103 "current security level" indicates a security level which is currently set in Supervisor. Attribute ID 401 "current count data" indicates a list of information as count targets in Supervisor, and its meaning is shown by attribute ID 402 "count data format". For example, count data 45, 78, 34, 13 indicate the number of print sheets having a paper size shown in the count data format. The attribute ID 402 "count data format" is shown as a list of attribute ID. Since the attribute ID is defined to be unique in the apparatus, by designating the attribute ID, the meaning of the count data can be designated. For example, an attribute value 565 of attribute ID 402 means the number of print sheets with a sheet size of A2, an attribute value 537 means the number of print sheets with a sheet size of A3, an attribute value 545 means the number of print sheets with a sheet size of A4, and an attribute value 523 means the number of print sheets with a sheet size of A5. Count limit data of attribute ID 403 shows a maximum value which the attribute ID 401 "current count data" can have. When even one of the values of "current count data" exceeds the maximum value, by invalidating a valid flag of the subaddress to service ID table shown in FIG. 9, CPU 301 invalidates all the services (by the manager). Count unit price data of attribute ID 404 shows a unit price for every count of the attribute ID retained in the attribute ID 402 "count data format" in terms of a currency unit. Current charge data of attribute ID 405 indicates a value obtained by multiplying corresponding values of the attribute ID 401 "current count data" and attribute ID 404 "count unit price data" and taking a sum. Charge limit data of attribute ID 406 shows a maximum value which the attribute ID 405 "current charge data" can have. When the attribute ID 405 "current charge data" exceeds an attribute ID 406 "charge limit data", by changing a valid flag to an invalid flag in the subaddress to service ID table shown in FIG. 9, the CPU 301 invalidates all the services (by the manager). A list of supported events of attribute ID 501 shows events which can be set to be notified to Supervisor by a list of event ID which is univocally defined for every event type. Actual event transmission is set by setting a connection type and addressee of event notification with event ID in the event setting table shown in FIG. 16. For the values of the attribute table of FIG. 7, description "Table Data" indicates that values (52 to 104) are data each having a table format shown by type ID.

(Subaddress to Service ID Table)

FIG. 9 shows a subaddress to service ID table. This table is retained in DISK 315 as attribute values of an attribute ID 1001 (subaddress to SID table) in the attribute table shown in FIG. 7. The subaddress to SID table shows a type of service (e.g., print, font download, and the like) obtained by placing the command packet in a subaddress, and the subaddress. Moreover, in accordance with the valid flag, and the like of the table, the interpreter 409 controls each connection form concerning whether a job service is provided. In the table each line shows one information unit (record), and the data is constituted as an aggregate of a plurality of records. Each record is constituted of a connection type ID 801, subaddress 802, service ID 803, valid flag 804, valid user list 805, and invalid user list 806. The connection type ID 801 indicates an identifier indicating the connection form. FIG. 10 is a diagram showing meanings of connection type ID: 0 denotes Internal (user interface); 1 denotes TCP/IP (network); 2 denotes IEEE 1284.4 (IEEE 1284); and 3 denotes SBP-2 (IEEE 1394).

The subaddress 802 shows a subaddress of each connection form. Although the user interface has no subaddress, for the sake of convenience the subaddress is allocated to the interface, and the command packet is placed together with subaddress information from the user interface.

The service ID 803 is an identifier indicating a service. The service ID 803 is allocated to each manager shown in FIGS. 4, 5 and 6 in one-to-one correspondence.

The valid flag 804 shows whether the subaddress is valid. When the value is true (YES), the subaddress is valid, so that the user can issue the command packet to the subaddress. When the value is false (NO), the subaddress is invalid, which means that even if the command packet is transmitted to the subaddress, the packet is canceled. FIG. 8 shows that when the connection form of connection type ID 2 (IEEE 1284) is used, a service of service ID 8 (print job manager) cannot be provided.

The valid user list 805 shows a list of user ID which can receive the service when the subaddress is valid. The invalid user list 806 shows a list of user ID which cannot receive the service even when the subaddress is valid. The value can be set to only one of the valid user list 805 and the invalid user list 806.

(Service ID to Task Type Table)

FIG. 11 shows a service ID to task type table. This table is retained in DISK 315 as attribute values of attribute ID 1002 (SID to Task Type Table) of the attribute table shown in FIG. 7. The service ID to task type table shows the type of service provided by the service ID. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of tasks. Each record is constituted of service ID 901 and task type 902. The task type 902 shows the type of service. FIG. 12 is a diagram showing meanings of values of the task type 902: 0 denotes the service performed by Supervisor; 1 denotes print; 2 denotes scan; 3 denotes copy; 101 denotes font; 102 denotes form overlay; 103 denotes log; and 104 denotes color profile. Service ID has a one-to-one correspondence with the manager which provides the service. Therefore, the service ID can be used for accessing a function table of each manager. Since each printer controller or scanner controller also has the function table, in order to access the table, a controller ID equivalent to the service ID is allocated to the printer controller or the scanner controller, and the type of controller shown by the controller ID is managed in the service ID to task type table. A task type 201 denotes a printer controller, and 202 denotes a scanner controller. The controller ID has a one-to-one correspondence with each controller shown in FIGS. 4 and 5.

Meanings of service ID are as follows:

0: Supervisor 410

1: print job manager 501

2: print job manager 502

3: print job manager 503

4: print job manager 504

5: print job manager 505

104: color profile manager 416

21: printer controller 510

22: printer controller 511

23: printer controller 512

24: scanner controller 420

(User Authentication Table)

FIG. 13 shows a user authentication table retained by Supervisor, and shows authentication information of users who can use the apparatus. This table is retained in DISK 315 as attribute values of attribute ID 1003 (user authentication table) of the attribute table shown in FIG. 7. The user authentication table shows a set of valid user ID and password, together with information as to whether the user has a manager privilege. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of records. Each record is constituted of user ID 1001, password 1002 and manager privilege flag 1003. The manager privilege flag 1003 indicates whether the user has a right as a manager.

(Access Control Table)

FIG. 14 is an access control table retained by Supervisor, and shows a security level of each service. This table is retained in DISK 315 as attribute values of attribute ID 1004 (access control table) of the attribute table shown in FIG. 7. The access control table retains the security level necessary for each service ID, and a list of users who are permitted to be given services. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of records. Each record is constituted of service ID 1101, security level 1102 and user ID list 1103. The security level 1102 shows authentication information necessary for receiving the service designated by the service ID 1101, that is, for issuing the command packet to the manager indicated by the service ID 1101. FIG. 15 shows meanings of security levels: security level 0 shows that user authentication is unnecessary; 1 shows that only the manager is discriminated; 2 shows that the service is available only for an authenticated user, but the user ID is used and no password is used for authentication; and 3 shows that the service is available only for the authenticated user, and the user ID and password are used for the authentication. The user ID list 1103 shows a list of user ID permitted to use (access) when the security level 1102 is 2 or 3.

(Event Setting Table)

FIG. 16 shows an event setting table retained by Supervisor. This table is retained in DISK 315 as attribute values of attribute ID 502 (event setting table) of the attribute table shown in FIG. 7. The event setting table retains, for each event type, a method of transmitting event notification and an addressee when a designated event occurs in the apparatus. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of records. Each record is constituted of an event ID 1201, connection type 1202 and notification addressee 1203. The addressee is constituted of the connection type and a notification address dependent on the connection type. The event ID 1201 shows an event type, and is defined to be unique in the apparatus. For example, Event ID 200 indicates that there is no paper, ID 399 indicates that there is no toner, ID 432 indicates that there is no ink, and ID 234 indicates that a cover of the multi-function peripheral is open. The connection type ID 1202 shows a connection type by which the event notification is transmitted, and values are the same as those which are used in the subaddress to service ID table of FIG. 9. The notification addressee 1203 shows event notification addressees suitable for the connection type 1202.

(Event Format Table)

FIG. 17 is an event format table retained by Supervisor showing event contents. This table is retained in DISK 315 as attribute values of attribute ID 503 (event format table) of the attribute table shown in FIG. 7. The event format table retains a type of additional data transmitted as the event notification, for each event ID defined to be unique in the apparatus. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of records. Each record is constituted of event ID 1301 and event format 1302. The event format 1302 is a type of the additional data transmitted as the event notification, and shown as an attribute ID list. The attribute ID is defined to be unique in the apparatus. Since the type is also univocally determined by the attribute ID, by designating the attribute ID, a format of the additional data can be shown. For example, an attribute ID 676 of the event format 1302 indicates a paper size, ID 756 indicates a paper type, ID 666 indicates a toner type, ID 698 indicates an ink type, and ID 600 indicates a cover position. As described hereinafter, event transmission methods and addressees are set in the data (attribute table) retained by each manager and controller, and the event which occurs in each manager and controller can be notified, but the additional data format of the event is also retained in the event format table shown in FIG. 17. When the designated event occurs, the content defined by the event format is notified with predetermined data for each event ID.

(Attribute Table of Print Job Manager)

FIG. 18 shows data (attribute table) retained by each of the print job managers (control programs) 501 to 509 in DISK 315. This table shows performances and functions of print jobs which can be handled by the print job manager. In the table each line shows one information unit (record), and data is constituted as an aggregate of a plurality of records. Each record content is the same as that of Supervisor shown in FIG. 7, and each record is constituted of attribute ID 1401, type ID 1402 and value 1403. FIG. 19 is a diagram showing values of attribute ID 1401 and type ID 1402 of the attribute table of FIG. 18. Type-IDs other than type ID 203 (job table type), type ID 204 (job request table type), type ID 81 (type of inhibited attribute combination list 1), type ID 82 (type of inhibited attribute combination list 2), type ID 83 (type of inhibited attribute combination list 3), type ID 84 (type of inhibited attribute combination list 4), and type ID 85 (type of inhibited attribute combination list 5) are the same as those which are used in the Supervisor attribute table of FIG. 7.

An attribute ID 601 "download method for supported data" shows a method of transmitting document data to be printed to the apparatus. In the embodiment supported are a method 1 which comprises including the document data in the job; and a method 2 which comprises including a reference pointer (URL: Unified Resource Locator) of the document data in the job, and reading the document data indicated by the reference pointer from the apparatus if necessary.

Attribute IDs 801 to 805 are inhibited attributes indicating limits on attributes to be set in the print job placed for the print job manager. These attributes are used to show limit items. For example, when the number of copy sheets exceed 100, finisher setting becomes impossible. There are five types of methods of representing the limits in the inhibited attributes. As shown in {attribute ID 1:{attribute ID 2}}, the attribute ID 801 holds a plurality of pairs of lists of another attribute ID 2 to a certain attribute ID 1. This means that when the attribute ID 1 is being set, the setting of each attribute ID 2 cannot be performed in a print job script.

As shown in {attribute ID 1:operator identifier:value:{attribute ID 2}}, the attribute ID 802 retains a plurality of pairs of lists of another attribute ID 2 relative to a certain attribute ID1, operator identifier and value. This means that in a case where the operator shown by the operator identifier for the attribute ID 1 is applied to the value, when a result is true, the setting of each attribute ID 2 cannot be performed in the print job script. The operator identifier has a one-to-one correspondence with calculation of two terms of integer values. For example, 0 denotes "=(equal)".

As shown in {attribute ID 1:operator identifier 1:value 1:{attribute ID 2:operator identifier 2:value 2}}, the attribute ID 803 retains a plurality of pairs of lists of a set of another attribute ID2, operator identifier 2 and value 2 relative to a certain attribute ID1, operator identifier 1 and value 1. This means that in a case where the operator shown by the operator identifier 1 for the attribute ID 1 is applied to the value 1, when a result is true, setting cannot be performed in the print job script in such a manner that a result of application of the operator indicated by the operator identifier 2 for each attribute ID2 to the value 2 becomes true.

As shown in {(attribute ID 1:operator identifier 1:value 1) operator identifier 3 (attribute ID 2:operator identifier 2:value 2):{attribute ID 3}}, the attribute ID 804 retains a plurality of pairs of lists of still another attribute ID3, relative to a certain attribute ID1, operator identifier 1 and value 1 and the operator identifier 3 and another attribute ID2, operator identifier 2 and value 2. This means that in a case where the result of application of the operator shown by the operator identifier 1 for the attribute ID 1 to the value 1 and the result of application of the operator shown by the operator identifier 2 for the attribute ID 2 to the value 2 are calculated as shown by the operator identifier 3, when a result is true, each attribute ID 3 cannot be set in the print job script.

As shown in {(attribute ID 1:operator identifier 1: value 1): operator identifier 3:(attribute ID 2:operator identifier 2:value 2):{attribute ID 4:operator identifier 4:value 4}}, the attribute ID 805 retains a plurality of pairs of lists of a set of still another attribute ID4, operator identifier 4 and value 4, relative to a certain attribute ID1, operator identifier 1 and value 1 and the operator identifier 3 and another attribute ID2, operator identifier 2 and value 2. This means that in a case where the result of application of the operator shown by the operator identifier 1 for the attribute ID 1 to the value 1 and the result of application of the operator shown by the operator identifier 2 for the attribute ID 2 to the value 2 are calculated as shown by the operator identifier 3, when a result is true, setting cannot be performed in the print job script in such a manner that when calculation is performed on each attribute ID 4 and calculation shown by 4 is applied to the value 4, a result becomes true.

The attribute ID 2001 "list of controller ID (possibly) executing Job" is a list of controller ID of the controller which executes the print job, and the print job managers other than the print job manager 508 are surely on a list of controllers which surely execute the job. Since the print job manager 508 dynamically selects the controller in accordance with the function demanded for the job, the attribute indicates a controller selection range. The attribute ID 2002 "controller auto selection is possible or not" indicates whether the print job manager automatically selects the controller. In the embodiment, only the print job manager 508 sets the value to be true. The other attribute IDs are the same as those which are used in the Supervisor attribute table of FIG. 7. However, setting ranges and influenced ranges are limited to those which are under control of the printer job manager to which the attribute table belongs. For example, an attribute value 101 "supported operation" is a list of operations which can be issued to the print job manager, and an attribute value 406 "charge limit data" puts a charge limit on the print job executed by the print job manager. For treatment in a case where the charge limit is exceeded, the service of the print job manager is merely invalidated, and services of the other managers are not influenced. Additionally, the attribute table of the print job manager shown in FIG. 18 is an attribute table of service ID 4 (print job manager 504), and attribute tables of print job managers 501, 502, 503, 505, 506, 507, 508, 509 corresponding to service IDs 1, 2, 3, 5, 6, 7, 8, 9, respectively are stored in DISK 315 and differ from one another.

FIG. 46 shows a structure of the command packet transmitted to the interpreter 409 from the user interface manager 405, the TCP/IP, UDP/IP processing module 406, the IEEE 1284.4 processing module 407 and the SBP-2 processing module 408. The command packet also shows structures of a reply packet and an event packet transmitted to the user interface manager 405, the TCP/IP, UDP/IP processing module 406, the IEEE 1284.4 processing module 407 and the SBP-2 processing module 408 from the interpreter 409. The packet comprises a packet header 3101 indicating a top of the packet, a packet version 3102 indicating a packet structure version, a flag 3103 indicating a packet property, an operation code 3104 indicating a type of operation to be performed, a block number 3105 used for Client (PC) to recognize the reply packet, a parameter length 3106 indicating a length of parameter 3110, user ID 3107 and password 3108 for use in user authentication, a status code 3109 used only in the reply packet and indicating a general reply state, and a parameter 3110 having a format determined for each operation code 3105. The parameter 3110 includes access target service ID, access target attribute ID, and the like. The flag 3104 includes a flag 3111 indicating that the packet is a command packet, event packet or reply packet, and a continuous flag 3112 indicating that data to be transmitted cannot be included in the parameter 3110 and continued data is also included in the packet to be transmitted next. The length of the parameter 3110 is limited to a numeral (64 k byte) indicative of the parameter length 3106. Specifically, Client PC 202 and 203 connected to Ethernet 208 designate IP address and port number to connect with the multi-function peripheral 201 and output IP packet data to Network Interface 305 (107). Client PC 204 connected to IEEE 1394 interface 206 designates node ID and LUN (logical unit number) to connect to the multi-function peripheral 201 and output SBP-2 packet data to IEEE 1394 Interface 306 (108). Client PC 205 connected to IEEE 1284 interface 207 designates the socket number to connect to the multi-function peripheral 201 and outputs IEEE 1284.4 packet data to IEEE 1284 Interface 307 (109). Via Network Interface Driver 402, IEEE 1284 Interface Driver 403, and IEEE 1394 Interface Driver 404, the command packets shown in FIG. 46 with IP Header, 1284 Header, and 1394 Header added to their tops, respectively, are outputted to the TCP/IP, UDP/IP processing module 406, the IEEE 1284.4 processing module 407, and the SBP-2 processing module 408. The TCP/IP, UDP/IP processing module 406, the IEEE 1284.4 processing module 407, and the SBP-2 processing module 408 process the received transport packets to extract the command packets shown in FIG. 46 and transmit outputs to Interpreter/Generator 409.

(Processing of Command Packet)

FIG. 47 shows a processing flow of the command packet in the multi-function peripheral 201. In step 3201, data transmitted from the interfaces 401 to 404 are processed by the transport processing modules 405 to 408 to extract the command packets shown in FIG. 46. The extracted command packets, together with information of the connection type by which the data is entered (connection type ID) and the subaddress, are transmitted to the interpreter 409 from the TCP/IP, UDP/IP processing module 406, the IEEE 1284.4 processing module 407, and the SBP-2 processing module 408. In step 3202, the interpreter 409 refers to the subaddress to service ID table (FIG. 9) retained by Supervisor 410, and compares the entered connection type ID and subaddress to obtain the service ID and to check whether or not the data input is valid. As a check result, when the data input is not valid, in step 3204 the command packet is canceled to end the flow. When the data input is valid, in step 3203 the command packet is analyzed based on the packet structure of FIG. 46. As a result of the packet analysis, each item shown in FIG. 46 is outputted as independent and separate information. In step 3205, by referring to the access control table (FIG. 14) based on the service ID, the security level for the service ID is obtained.

In step 3206, it is checked whether the security level obtained in the step 3205 is 0 or 1. When the security level is 0 or 1, data is transmitted to the dispatcher 412 without checking the security level (security gate 411). In the step 3206, when the security level is other than 0 and 1, in step 3207 it is checked whether or not the security level is 2. When the security level is 2, in step 3209 it is checked whether or not the user ID included in the command packet is in the user authentication table (FIG. 13). When the user ID is not included, it is judged that there is no authority. In step 3210 error reply information is generated, a packet is generated by the interpreter 409 (fill the status code 3109 with error information), and the packet is sent to a command packet sender. When the user ID is included, data is transmitted to the dispatcher 412. A sender address is extracted from the transport packet (Header). In step 3207, when the security level is other than 2, in step 3208 it is checked whether the pair of user ID and password included in the command packet is present in the user authentication table (FIG. 13). When the pair of user ID and password is not included, it is judged that there is no authority. In step 3211 the error reply information is generated, the packet is generated by the interpreter 409, and the packet is sent to the command packet sender. When the user ID is included, data is transmitted to the dispatcher 412. In step 3212 the dispatcher 412 determines a distribution addressee manager based on the service ID, and distributes to the determined manager the connection type ID and subaddress to which the data is transmitted, sender address, operation code, block number, flag information, user ID, password, parameter length and parameter. Subsequently, in step 3213 each manager processes these information.

(Access Processing of Attribute Table)

FIG. 48 shows a processing when Client instructs reading or writing for the attribute table of each manager or controller retained by the multi-function peripheral 201. The reading and writing for the attribute table retained by each manager or controller are performed by transmitting an appropriate command packet to the subaddress of Supervisor. In the attribute table reading command packet, as parameters, access target service ID and access target attribute ID are included. Moreover, in the attribute table writing command packet, as parameters, access target service ID, access target attribute ID and attribute value corresponding to the attribute ID are included. The packet data transmitted to the multi-function peripheral 201 from Client is processed by the flow shown in FIG. 47, and distributed to Supervisor. In step 3301 it is checked whether or not the operation code 3104 is a code for reading the attribute value ("Get"). When the operation code is "Get", in step 3301 based on the service ID the entire attribute table of the access target is obtained. When the service ID is 0, the attribute table of Supervisor 410 shown in FIG. 7 is obtained. When the service ID is 1, 2, 3, 4, 5, 6, 7, 8, 9, the attribute table of the print job manager as shown in FIG. 18 is obtained. When the service ID is 10, the attribute table of the scan job manager 419 as shown in FIG. 22 is obtained. When the service ID is 11, 12, 13, 14, 15, 16, 17, 18, the attribute table of the copy job manager a shown in FIG. 24 is obtained. When the service ID is 101, the attribute table of the font manager 413 as shown in FIG. 26 is obtained. When the service ID is 102, the attribute table of the form overlay manager 414 as shown in FIG. 29 is obtained. When the service ID is 103, the attribute table of the log manager 415 as shown in FIG. 32 is obtained. When the service ID is 104, the attribute table of the color profile manager 416 as shown in FIG. 37 is obtained. When the service ID is 21, 22, 23, the attribute table of the printer controller as shown in FIG. 40 is obtained. When the service ID is 24, the attribute table of the scanner controller 420 as shown in FIG. 44 is obtained. Additionally, the attribute table of the print job manager shown in FIG. 18 is an attribute table of service ID 4 (print job manager 504), and the attribute tables of print job managers 501, 502, 503, 505, 506, 507, 508, 509 corresponding to service ID 1, 2, 3, 5, 6, 7, 8, 9, respectively, are stored in DISK 315. In the same manner, the attribute table of the copy job manager shown in FIG. 24 is an attribute table of service ID 18 (copy job manager 608), and the attribute tables of copy job managers 601 to 607 corresponding to service IDs 11 to 17, respectively, are stored in DISK 315. Furthermore, in the same manner, the attribute table of the printer controller shown in FIG. 40 is an attribute table of service ID 21 (printer controller 510), and the attribute tables of printer controllers 511, 512 corresponding to service IDs 22, 23, respectively, are stored in DISK 315.

Thereafter, in step 3303, it is examined whether or not the designated attribute value can be obtained. The examination is performed by obtaining a value of "attribute ID list available only for the manager" (attribute ID=105) of the target attribute table, and checking whether or not the attribute ID instructed to be obtained is included. When the attribute ID is included, the value cannot be obtained. Therefore, in step 3305 the error reply packet is generated, and transmitted, thereby ending the flow. When the attribute ID is not included, in step 3304 the attribute table is searched based on the designated attribute ID, and pattern ID having the corresponding attribute ID and attribute value are obtained. In step 3306, based on the pattern ID the reply paket is generated, and in step 3307 the reply packet is transmitted, thereby ending the flow. When in step 3301 the operation code is not "Get", in step 3308 it is checked whether or not the operation code is an attribute value writing code ("Set"). When the operation code is "Set", in step 3309 based on the service ID an access target attribute table is entirely obtained. Thereafter, in step 3310, it is examined whether or not the designated attribute value can be set. The examination is performed by obtaining a value of "attribute ID list which can be set only by the manager" (attribute ID=104) of the target attribute table, and checking whether or not the attribute ID instructed to be set is included. When the attribute ID is included, the value cannot be obtained. Therefore, in step 3314 the error reply packet is generated, and transmitted, thereby ending the flow. When the attribute ID is not included, in step 3311 based on the designated attribute ID the attribute table is searched, and the pattern ID having the corresponding attribute ID and attribute value are obtained. In step 3312, the attribute value designated based on the pattern ID is set, and the reply packet informing that the setting has succeeded is generated. In step 3313 the reply packet is transmitted, thereby ending the flow. In step 3308 when the operation code is not "Set", another processing step 3315 described later is performed in accordance with the operation code to end the flow.

(Service ID List Inquiry Processing)

FIG. 49 shows a processing when Client inquires a list of services (list of service ID) provided by the multi-function peripheral 201. The inquiry for the service list is performed by transmitting an appropriate command packet to the subaddress of Supervisor, and reading and processing the subaddress to service ID table shown in FIG. 9. The flow shown in FIG. 49 shows details of the step 3315 (processing of other Operation Code) of the flow shown in FIG. 48. In step 3401, it is checked whether or not the operation code is a service list obtaining code ("List Service"). When the operation code is not "List Service", other processing step 3402 described later in accordance with the operation code is performed to end the flow. In step 3401, when the operation code is "List Service", in step 3403, only the service IDs corresponding to the connection type ID used in the inquiry are extracted from the subaddress to service ID table to generate the list. In step 3404, each record of the list prepared in the step 3403 is examined. When the valid flag 804 is valid, and there is a value in the valid user list 805, the record not corresponding to the value for the user ID used in the inquiry is deleted. When there is a value in the invalid user list 806, the record corresponding to the value for the user ID used in the inquiry is deleted from the list. In step 3405, the reply packet including the service ID list updated in the step 3404 is generated, and the generated reply packet is transmitted in step 3406.

(Subaddress Inquiry Processing)

FIG. 50 shows a processing when Client designates service ID to inquire subaddress information necessary for using the service provided by the multi-function peripheral 201. The inquiry of the subaddress is performed by transmitting an appropriate command packet to the subaddress of Supervisor 410, and reading and processing the subaddress to service ID table shown in FIG. 9. The subaddress inquiry command packet includes the service ID as the parameter. The flow shown in FIG. 50 shows details of the step 3402 (processing of other Operation Code) of the flow shown in FIG. 49. In step 3501, it is checked whether or not the operation code is a subaddress obtaining code ("Reserve"). When the operation code is not "Reserve", other processing step 3502 described later in accordance with the operation code is performed to end the flow. In step 3501, when the operation code is "Reserve", in step 3502, from the connection type ID used in the inquiry and the service ID designated in the parameter, the subaddress to service ID table is scanned to search for the corresponding record. For the record searched in the step 3504, it is checked whether or not the valid flag is valid. When there is a value in the valid user list, it is checked whether or not the user ID used in the inquiry is in the list. When there is a value in the invalid user list, it is checked whether no user ID used in the inquiry is in the list. As a check result, when answer is not OK, it is judged that there is no right to access (right to use) the designated service. In step 3506 the error reply packet is generated, and in step 3507 the packet is sent, thereby ending the flow. As a result of the check in the step 3504, when the answer is all OK, in step 3505 the reply packet including the subaddress is generated, and in step 3507 the packet is sent, thereby ending the flow.

(Task Type Designated Service ID Inquiry Processing)

FIG. 51 shows a processing flow for designating a service type and inquiring an optimum service ID to process the designated type of service, among the services provided by the multi-function peripheral 201. The inquiry of the service ID with the designated service type is performed by transmitting an appropriate command packet to the subaddress of Supervisor, and reading and processing the subaddress to service ID table shown in FIG. 9 and the service ID to task type table shown in FIG. 11. The subaddress ID inquiry command packet includes the task type for designating the service type, and a combination (condition information) for limiting the service as parameters. The condition information is shown as a list of a pair of attribute ID and value. The flow shown in FIG. 51 shows details of the step 3503 (processing of other Operation Code) of the flow shown in FIG. 50. In step 3601, it is checked whether or not the operation code is a subaddress obtaining code ("Get Service"). When the operation code is not "Get Service", other processing step 3603 described later in accordance with the operation code is performed to end the flow. In the step 3601 when the operation code is "Get Service", in step 3602 from the connection type ID used in the inquiry and the subaddress to service ID table, a service ID list having the connection type ID used in the inquiry is generated. In step 3604, the service ID to task type table is referred to, and a list of service IDs having the designated task type is generated from the above-described list. In step 3605, each record of the list generated in the step 3604 is examined. When the valid flag 804 is valid, and there is a value in the valid user list 805, the record not corresponding to the value for the user ID used in the inquiry is deleted. When there is a value in the invalid user list 806, the record corresponding to the value for the user ID used in the inquiry is deleted from the list. In step 3609, the condition information included in the parameter and the attribute table of each manager for the service ID in the list are compared, and values other than values satisfying the conditions are deleted from the list. In step 3606, the number of records of the list changed in the step 3605 is checked. When the number of records is 0, it is judged that there is no requested service. In step 3611 the error reply packet is generated, and in step 3613 the reply packet is sent, thereby ending the flow. In the step 3606 when the number of records is other than 0, in step 3607 it is checked whether or not the number of records is 1. When the number of records is 1, in step 3612 the reply packet including the obtained service ID is generated, and in step 3613 the reply packet is sent, thereby ending the flow. In the step 3607, when the number of records is other than 1, in step 3608, the current load state is inquired of each manager for the service ID in the list. The managers return the number of jobs being processed as the load state, and from these the manager having a lowest load is selected. In step 3610, the reply packet including the service ID of the selected manager is generated, and in the step 3613 the reply packet is sent, thereby ending the flow.

(Job Structure)

FIG. 52 shows an inner structure of a file (job file) which retains the job entity managed by each manager. The file name of the job file is retained in the file name 1502 of the job table (FIG. 20). The file structure also shows an inner structure of a file retaining the job entity managed by each controller. The file name is retained in the file name 2903 of the job queue table (FIG. 42). The job entity is constituted of a plurality of continuous sets of attribute ID 3701, attribute value size 3702 and attribute value 3703. When the job includes data, as shown in 3707, 3708, 3709, a value indicating data as the attribute ID, file name size as the attribute value size, and file name of the file retaining the document data as the attribute value are retained. The attribute includes data transmission method, data format (used PDL, and the like), event type and information such as addressee to which event notification is sent when the event occurs, and information dependent on the job type such as, for the print job, the number of copy sheets, finishing processing designation, designation of font for use, designation of form overlay for use, and the like.

(Job Script Processing in Each Manager)

FIGS. 53 and 54 show a processing flow of the job script in each manager. The job script is constituted of a series of command packets shown in FIG. 46, and prescribed to start with operation code "Job Start" and end with operation code "Job End". Each packet constituting the job script is placed in the subaddress shown by the subaddress to service ID table shown in FIG. 9, and distributed to each manager by the command packet processing flow shown in FIG. 47. The processing flow shown in FIG. 53 is a processing flow for processing the command packet distributed to each manager to generate the job file and data file shown in FIG. 52. For the operation distributed to each manager, in step 3801 it is checked whether or not the operation code is a supported operation code. The check is performed by comparing with the value of attribute 4 supported operation" (attribute ID 101) retained in the attribute table by each manager. As a result of the check, when the operation is not supported, in step 3816 the error reply packet is generated and sent, thereby ending the flow. In the step 3801 when the operation code is supported, in step 3802 it is checked whether or not the job is being executed. The check is performed by examining whether or not a job execution flag (flag set in step 3806) is true. As a result of the examination, when the job execution flag is false, and the job is not executed, in step 3804 it is checked whether or not the operation code is "Job Start". As a result of the check, when the operation code is not "Job Start", in step 3816 the error reply packet is generated and sent, thereby ending the flow.

When the answer to the step 3804 is OK, in step 3805 the job ID is allocated to add an item to the job table (FIG. 20), and a new job file is generated. Thereafter, in step 3806 the job execution flag is set to be true, thereby ending the command packet processing. In the check of step 3802, when the job execution flag is true, in step 3803 it is checked whether the operation code is "Send". The operation code "Send" informs the manager that the parameter includes data constituting the job. In the step 3803 when the operation code is "Send", in step 3807 a continuation flag entered with the command is checked. When the continuation flag is true, in step 3808 a new area is added to already present data file 3713, and in 3809 the parameter is written in the area, thereby ending the flow. In the step 3807 when the continuation flag is false, in step 3810 new data file 3713 is generated, and in step 3811 the parameter is written in the data file. Thereafter, in step 3812 a new area is added to the job file, and in step 3813 the attribute ID 3707 indicating data, the file name size 3708 and the file name 3709 of the new generated file are written in the area, thereby ending the flow. In the step 3803 when the operation code is not "Send", in step 3814 it is checked whether the operation code is "Job End". When the operation code is "Job End", in step 3815 job generation processing is terminated, thereby ending the flow. The job generation terminating processing includes processings such as closing of the job file, and the like, and differs with manager types (print job, scan job, copy job, font, form overlay, log, color profile).

In the step 3814, when the operation code is not "Job End", in step 3817 it is checked whether the operation code is "Set Job". The operation code "Set Job" informs the manager that the parameter includes the attribute (attribute ID and attribute value) constituting the job. When the job operation code is "Set Job", in step 3818 a new area is added to the job file, and in step 3819 the attribute ID, attribute value size and attribute value are written in the added area, thereby ending the flow.

In the step 3817, when the operation code is not "Set Job", in step 3820 it is checked whether the operation code is "Send Request". The operation code "Send Request" instructs the manager to transmit the data, and the data transmission method is included as the parameter. When the operation code is "Send Request", in step 3821 a processing according to each manager is performed to end the flow. In the processing of the step 3821 for the scan job manager, the scanner controller is instructed to scan the original in accordance with the attribute value retained in the job file, and to transmit obtained data in a designated method. For the font manager, the processing includes transmission of the font data designated as the attribute value in the job file immediately in a designated transmission method. In the step 3820 when the operation code is not "Send Request", in step 3822 other operation codes are processed to end the flow.

(Job Processing in Print Job Manager)

FIG. 55 shows a job processing flow in the print job managers 501 to 509 shown in FIG. 5. The print job manager operates a task of constantly monitoring the job table. The print job manager performs the job script processing flow shown in FIG. 54. Subsequently, when it is detected that a new item is added to the job table by input of operation code "Job Start", the monitor task operates a task having the processing flow shown in FIG. 55 to process the input job. In step 3901 the manager waits until an attribute indicating a PDL (Page Description Language) type used in representation of data (document data) is added to the job file. When the PDL type is determined, the manager waits until PDL Rasterizer for use (PDL Rasterizer 417 or 418) can be used. In the step 3901 when the PDL Rasterizer becomes ready for use, in step 3902 the manager waits until the attribute indicating data reception method is added to the job file. When the attribute indicating the data reception method is added to the job file, in step 3903 the data reception method is checked. When the data reception method comprises accessing an external source (e.g., Client PC on the network, and the like) of the multi-function peripheral 201, in step 3904 a task for reading the designated data is generated to access the external source. Subsequently, in the step 3905 the manager waits for start of the data reading. When in the step 3903 data is included in the job (in FIG. 54 in data reception by operation code "Send"), in step 3906 the manager waits for start of data reception.

When in the step 3905 or 3906 the data reading or reception is started, in step 3907 data starts to be handed to PDL Rasterizer. Subsequently, in step 3908 image data is received from PDL Rasterizer. In step 3909 the printer controller to be used is determined. The determination includes a case where the controller is predetermined by the attribute ID 2001 (list of Controller ID executing Job) of the attribute table of the print job managers 501 to 507 and 509, and a case where attribute ID 2002 (Controller automatic selection is possible or not) of the print job manager 508 is designated to be possible and the printer controller necessary for print is dynamically determined by reading the print job file content (attribute ID and attribute value of the job file shown in FIG. 52). In this case, for example, if color printing is designated by the attribute ID and attribute value in the job file, Ink Jet Controller 512 (CID 23) is determined. When the use of Finisher is designated by the attribute ID and attribute value, LBP Controller 510 (CID 21) is determined. When the printer controller is determined, in step 3910 image data is handed to each printer controller and job ID is received from the printer controller. In step 3911 in the job request table (FIG. 21), the job ID, printer controller ID, and job ID received from the printer controller are recorded as separate record for each printer controller. Subsequently, in step 3912 the print job manager waits for job end in each printer controller. When the job end is notified from the printer controller, in step 3913 the corresponding record is deleted from the job request table. In step 3914 it is checked whether all the requested jobs of the printer controllers are finished. When the job still remains in the printer controller, the flow returns to the step 3912 to wait for the job end in the printer controller. When in the step 3914 the requested jobs in all the printer controllers are finished, in step 3915 the job record is deleted from the job table (FIG. 20). In this case, the event transmission processing shown in FIG. 61 is performed. In step 3916, the job file is searched, and in step 3917 it is checked whether there is an attribute value instructing the event transmission concerning the job end. If not, the processing ends. When the attribute value is present, in step 3918 the attribute value is read to obtain the transmission method and addressee. In step 3919 the event transmission packet is generated, and the event is sent to the designated transmission method and addressee. In step 3920, termination processings such as deletion of the job and data files, and the like are performed, thereby ending the job processing.

(Job Processing in Scan Job Manager)

FIG. 56 shows a job processing flow in the scan job manager 419. After the handing of the job is finished, the scan job manager starts a job processing. Therefore, the scan job manager starts the job processing of FIG. 56 as the job termination processing of the step 3815 in FIG. 54. In step 4001, the job is handed to the scanner controller 420 and job ID is received. In step 4002, to the job request table (FIG. 21), the job ID, scanner controller ID, and job ID received from the scanner controller 420 are recorded. In step 4003 the scan job manager waits for job end from the scanner controller 420. When the job end is notified from the scanner controller 420, scanned image data is received from the scanner controller 420, and in step 4004 the job record is deleted from the job table (FIG. 20). In this case, the event transmission processing shown in FIG. 61 is performed. In step 4005 the job attribute data is searched for the attribute instructing the data transmission method. When in step 4006 for the data transmission method the data is instructed to be sent as a script, in step 4008 the data is transmitted with other attribute information as the script. Details of processing for data transmission from the apparatus are shown in FIG. 62. When in the step 4006 reference transmission of data is instructed, in step 4007 the data is stored in the apparatus, and reference information for the data is transmitted with the other attribute information as the script. In step 4010 the job file is searched, and in step 4011 it is checked whether there is an attribute value instructing the event transmission concerning the job end. If not, the processing ends. When the attribute value is present, in step 4012 the attribute value is read to obtain the transmission method and addressee. In step 4013 the event transmission packet is generated, and the event is sent to the designated transmission method and addressee. In step 4014, termination processings such as deletion of the job and data files, and the like are performed, thereby ending the job processing.

(Job Processing in Copy Job Manager)

FIG. 57 shows a job processing flow in the copy job managers 601 to 608. After the handing of the job is finished, the copy job manager starts a job processing. Therefore, the copy job manager starts the job processing of FIG. 57 as the job termination processing of the step 3815 in FIG. 53. In step 4101, the job is handed to the scanner controller 420 and job ID is received. In step 4102, to the job request table (FIG. 21), the job ID, scanner controller ID, and job ID received from the scanner controller 420 are recorded. In step 4103 the manager waits for job end from the scanner controller 420. When the job end is notified from the scanner controller 420, scanned image data is received from the scanner controller 420, and in step 4104 the job record is deleted from the job table (FIG. 20). Subsequently, in step 4105 the printer controller to be used is determined. The determination includes a case where the controller is predetermined by the attribute ID 2001 (list of Controller ID executing Job) of the attribute table of the copy job managers 601 to 607 and 609, and a case where attribute ID 2002 (Controller automatic selection is possible or not) of the copy job manager 608 is designated to be possible and the printer controller necessary for print is dynamically determined by reading the job file content (attribute ID and attribute value of the job file shown in FIG. 52). In this case, for example, if color printing is designated by the attribute ID and attribute value in the job file, Ink Jet Controller 512 (CID 23) is determined. When the use of Finisher is designated by the attribute ID and attribute value, LBP Controller 510 (CID 21) is determined. When the printer controller is determined, in step 4106 the image data received from the scanner controller 420 is handed to each printer controller and job ID is received from the printer controller. In step 4107, to the job request table (FIG. 21), the job ID, printer controller ID, and job ID received from the printer controller are recorded as separate record for each printer controller.

Subsequently, in step 4108 the print job manager waits for job end in each printer controller. When the job end is notified from the printer controller, in step 4109 the corresponding record of the finished job is deleted from the job request table. In step 4110 it is checked whether all the requested jobs of the printer controllers are finished. When the job still remains in the printer controller, the flow returns to the step 4108 to wait for the job end in the printer controller. When in the step 4110 the requested jobs in all the printer controllers are finished, in step 4111 the job record is deleted from the job table (FIG. 20). In this case, the event transmission processing shown in FIG. 61 is performed. In step 4112, the job file is searched, and in step 4113 it is checked whether there is an attribute value instructing event transmission concerning the job end. If not, the processing ends. When the attribute value is present, in step 4114 the attribute value is read to obtain the transmission method and addressee. In step 4115 the event transmission packet is generated, and the event is sent to the designated transmission method and addressee. In step 4116, termination processings such as deletion of the job and data files, and the like are performed, thereby ending the job processing.
