Description

  The present invention relates to a printing system for storing print data in an image forming apparatus and printing the stored print data from a desired image forming apparatus, an image forming apparatus, a processing method therefor, and a program.

  Conventionally, so-called “pull printing (accumulation printing)” in which print data is output from a printing apparatus by making a print request from the printing apparatus (hereinafter referred to as a multi-function peripheral) to print data temporarily accumulated on a server. The printing system is known.

  Accordingly, the user can output print data from a desired printing apparatus instead of outputting to a specific printing apparatus during printing from an application (for example, Patent Document 1).

JP 2009-176202 A

  In a pull printing system such as the above-described printing system, when a user is in a situation where a normally used printing apparatus cannot be used by specifying and inputting an external printer server instead of a specific printing apparatus. However, it is possible to go to another available printing apparatus and issue a print instruction to the printer server.

  However, in the pull print system such as the above-described printing system, it is necessary to install a server outside, and a plurality of servers may be installed depending on the number of users to be used. In such a system configuration, a server management load increases, so a system that does not construct a server is desired.

  When constructing a system that does not construct a server, a configuration in which print data is temporarily stored on an HDD of a printing apparatus is conceivable. However, instead of a printing apparatus that is normally used, another desired printing apparatus can be used. In order to output one data, it is necessary to notify all the other printing apparatuses constituting the system of the storage location of the print data.

  However, in the system described above, it is necessary to register the notification destination in advance in all the printing devices, and in a printing device where the number of installed devices is likely to increase or decrease, troublesome maintenance of the notification destination occurs, and the actual operation It was difficult.

  In addition, instead of registering the notification destination in advance, a method of notifying the storage location information by broadcast can be considered. However, since broadcast notification is limited to the same segment, there is a high possibility that segments are separated in a large-scale user environment, and print data can be output only from a limited range of printing apparatuses. In broadcast communication, since the success or failure of notification cannot be confirmed, it is necessary to notify the storage location every time print data is received from the client terminal, which may cause an excessive load on the network.

Furthermore, it is conceivable to construct a server with a management server function for managing the bibliographic information of Patent Document 1, but each time print data is received by the printing apparatus, the print data information is changed to the bibliographic information. It must be transmitted to the printing apparatus to be managed, which increases the network load. Also, since the printing device has a different device spec than the server, it is difficult to perform the same operation as a server that places a heavy load on the printing device that manages bibliographic information.

FIG. 19 is a process outline diagram of the printing system (printing system).

FIG. 19 shows an outline of processing for receiving print data from the client PC 200 and notifying name information, processing for acquiring a print data list after logging in to the multifunction peripheral, printing of print data displayed in the list, and processing for deleting. Yes.
First, an outline of print data reception and name information notification processing will be described.

  (1) After using the printer driver on the client PC 200 to generate print data, the print data is transmitted (printed) to the multifunction peripheral 300-1 designated as the transmission destination in advance by the printer driver.

(2) The multifunction device 300-1 receives the print data and analyzes the print setting information (bibliographic information) included in the header of the print data. Also, the model name of the printer driver used to generate the print data is received from the client PC 200, and the bibliographic information extracted from the header of the print data is added to form a bibliographic information file as shown in FIG. Save to HDD 304.
(3) After extracting the bibliographic information, the print data received from the client PC 200 is stored in the HDD 304 on the multifunction machine 300-1.

(4) After receiving the print data from the client PC 200, the MFP 300-1 receives name information including the user name, model name, and host name (storage destination) of the print apparatus included in the bibliographic information file. Then, the MFP 300-2 having a name service function registered in advance is notified.
(5) The MFP 300-2 stores the received name information in the HDD 304 as a name information file as shown in FIG.
Next, an outline of processing for acquiring a print data list after the user logs in will be described.

  (6) The MFP 300-3 receives the user login notification from the authentication program and acquires the login user information. (7) The multifunction device 300-3 transmits a name information acquisition request including the user name included in the login user information and the model name of the own device to the multifunction device 300-2. The device information (IP address, host name, etc.) of the multifunction device 300-2 that makes a name information acquisition request is stored in the multifunction device 300-3 in advance.

  (8) The MFP 300-2 searches for a host name (storage destination) included in the name information file in which the user name, the host name, and the file name included in the received name information acquisition request match. (9) The host name (storage destination) as a result of the search is returned to the MFP 300-3. In this embodiment, a file name whose user name and host name match is selected as a search target. However, even a multifunction device with a different host name (for example, a different model) can use a multifunction device that can draw print data. Since it is feasible if it exists, the user name may be used for the search. For example, current multi-function peripherals can interpret general-purpose formats such as XPS data (XPS: XML Paper Specification). It is also possible to receive XPS data from a printer driver, interpret the XPS data with a multifunction peripheral, and perform drawing processing. Therefore, any multifunction device capable of interpreting XPS data can execute printing, so it is sufficient that at least the user name can be searched.

When a plurality of host names (storage destinations) are included in the name information received from the MFP 300-2, a bibliographic information acquisition request is transmitted to all host names (storage destinations) including the self-device.

  (11) In response to the received bibliographic information acquisition request, the multifunction machine 300-1 searches for the bibliographic information of the user that matches the user name. (12) The retrieved bibliographic information is transmitted to the multifunction machine 300-3. The bibliographic information may be configured to transmit necessary bibliographic information. For example, information that can specify print data such as a file name is transmitted.

(13) The multifunction device 300-3 stores the received bibliographic information in the RAM 302 and displays the list on the operation unit 308. When bibliographic information is received from a plurality of host names (storage destinations), all the bibliographic information is merged and displayed in a list.
Next, an outline of processing from reception of a print instruction from the user to printing will be described.

  (14-1) The bibliographic information (print data) displayed in a list is selected from the user, and upon reception of a press of a print instruction, the multifunction peripheral 300-3 acquires a print request, and the selected print data A print request including a file name is transmitted to the host name (storage destination). When the host name (storage destination) of the print data selected by the user extends over a plurality of multifunction devices, a print request is transmitted to all multifunction devices including the self-device.

(15-1) In response to the received print request, the multifunction peripheral 300-1 acquires print data from the file name included in the print request from the HDD 304 in the own apparatus. (16-1) The acquired print data is transmitted to the MFP 300-3. (17-1) The MFP 300-3 prints the received print data.
Next, an outline of processing from receiving a deletion instruction from the user to deleting the name information will be described.

  (14-2) The bibliographic information (print data) displayed in a list is selected from the user, and upon receiving a press of a delete instruction, the multifunction peripheral 300-3 acquires a delete request, and the selected print data A delete request including the file name is transmitted to the host name (storage destination). As in the case of a print request, when a plurality of multifunction devices are used, a deletion request is transmitted to all multifunction devices including the self-device.

  (15-2) In response to the received deletion request, the MFP 300-1 deletes the status 1401 in the bibliographic information file corresponding to the print data from the file name included in the deletion request from the HDD 304 in the own apparatus. change. Note that when a deletion request is received, it is possible to delete the bibliographic information and delete the print data.

  (16-2) When all the printable data statuses 1401 of the corresponding user have been deleted in the MFP 300-1, the MFP 300-1 gives the MFP 300-2 a user name, model name, A name information deletion notification including the host name (storage destination) of the local device is transmitted. If there is even one printable data, the name information deletion notification is not transmitted. (17-2) The MFP 300-2 deletes the corresponding host name from the name information file stored in the HDD 304 in accordance with the corresponding name information included in the received name information deletion notification.

Next, the processing of this embodiment will be described in detail with reference to FIGS.
Note that the programs and services described in the present embodiment are installed in the multi-function peripheral as software.
Each step is executed by the CPU (CPU 201 or CPU 301) of each device (client PC 200 or multifunction machine 300-1, 300-2, 300-3).

FIG. 5 is a flowchart of print data generation and reception in the present embodiment. FIG. 6 is a flowchart of printing data name information notification and registration in the present embodiment. Each process will be described together with the number of steps.
In step S100, the printer driver on the client PC 200 transmits print data to the multi function peripheral 300-1 in response to a print instruction from the user.

  In step S101, the bibliographic information service of the MFP 300-1 obtains the print data that is monitored in advance and received by the print data reception port (LPR515 port or RAW 9100 port) and transmitted by the client PC 200 in S100.

  In step S102, the bibliographic information service of the multifunction peripheral 300-1 acquires the model name (for example, MFP 5050) of the printer driver used for creating the print data from the client PC 200 from the acquired print data. The model name acquired here may be configured to be used when determining a model that can output the generated print data. For example, it is possible to output to models belonging to the same group by grouping each model and grouping and managing model information in group information that can be output.

In step S103, the bibliographic information service of the MFP 300-1 extracts various print data information (bibliographic information) as shown in FIG. 14 included in the print data header received from the client PC 200.
That is, steps S102 to S103 are processing for acquiring bibliographic information for managing the print data in response to reception of the print data.

  In step S104, the bibliographic information service of the MFP 300-1 creates a bibliographic information file as shown in FIG. 14 based on the bibliographic information extracted in step S103, and stores it in a predetermined directory of the MFP 300-2. To do.

  Here, the bibliographic information file in FIG. 14 will be described. FIG. 14 is a diagram illustrating an example of a bibliographic information file. The bibliographic information file is stored in the HDD 304.

For the bibliographic information file, the user name (that is, user identification information) who created the print data by logging in to the client PC 200, the document name of the print data, the time stamp indicating the generation time of the print data, double-sided / single-sided, 2in1, color / Print setting information 1403 as shown in monochrome is included. In addition, the model name 1405 of the printer driver used to create the print data acquired from the client PC 200, the unique file name 1402 generated when the print data is received, the status 1401 indicating the processing content of the print data, the host of the own apparatus Name (print data storage destination) 1404 and the like.
The bibliographic information may be any file format as long as it is managed for each print data, and may be a database or a table.

In step S105, the bibliographic information service of the MFP 300-1 generates the bibliographic information file in step S104, and then prints the print data received from the client PC 200 with the unique file name 1402 generated when the print data is received. -2 in a predetermined directory (HDD 304).
That is, steps S104 to S105 are processes for storing print data and bibliographic information.

  Next, moving to FIG. 6, in step S <b> 106, the bibliographic information service of the multifunction peripheral 300-1 acquires a notification name service list as shown in FIG. 17 registered in advance. In the system configuration diagram of FIG. 1, the multifunction device of the notification name service is the multifunction device 300-2.

  Here, FIG. 17 will be described. FIG. 17 is a diagram illustrating an example of a name service notification destination. The name service notification destination is stored in the HDD 304. Has been.

FIG. 17 shows the IP address of the MFP 300-2 operating as the name service as the name service notification destination. The host name may be used instead of the IP address.
In step S107, the bibliographic information service of the multifunction peripheral 300-1 acquires a notified name service list as shown in FIG.

  Here, FIG. 18 will be described. FIG. 18 is a diagram illustrating an example of a notified name service list. The notified name service list is stored in the HDD 304.

  The notified name service list is managed for each name of the user who has logged in the client PC 200 and created print data and the model name of the printer driver used to generate the print data, and has received the name information in step S111. IP address. The host name may be used instead of the IP address.

  Further, when print data is created by the same user using the same model printer driver and the print data is received by the multifunction device 300-1, the previous name service multifunction device 300-2 is affected by the network or the like. As long as the notification has not failed, the notified name service list is registered with the same notified party (IP address) as the notified name service list as shown in FIG. 17 acquired in step S106. When the name service is deleted from the notified name service list in step S427 or when the notification fails, the notified name service list (FIG. 18) and the notified name service list (FIG. 17) do not match. .

  On the other hand, when print data is created using a user who has generated print data for the first time or a printer driver of a model that is used for the first time, and the print data is received by the MFP 300-1, the notified name service list is It will be acquired in the sky. In addition, even when there is no printable data due to a deletion instruction from the user and the deletion notification is correctly performed, the notified name service list is acquired empty.

  In step S108, the bibliographic information service of the MFP 300-1 determines whether the notified name service is registered in the notified name service list acquired in step S107. If it is determined that at least one name service has been registered, the MFP 300-2 bibliographic information service proceeds to step S109, and at least one name service has been registered. If it is determined that it is not, the process proceeds to step S111.

In step S109, the bibliographic information service of the MFP 300-1 obtains the name service determined in step S108 that it has been registered that at least one notification has been registered, and the notification destination name service as shown in FIG. Remove from target. That is, the name service notification destination of FIG. 17 is held in the RAM 302, and the notified neal service list of FIG. 18 is deleted from the name service notification destination stored in the RAM 302.
As a result, regarding the notified name service, it is determined that the name information has already been notified, and the name service is deleted from the notification target, and unnecessary communication is not performed.

  In step S <b> 110, the bibliographic information service of the multifunction peripheral 300-1 determines whether the notification destination name service exists in the RAM 302. If it is determined that at least one notification destination name service exists, the bibliographic information service of the MFP 300-1 advances the processing to step S111, and if there is no notification destination name service. If determined, the process is terminated.

  In step S111, if it is determined in step S108 that there is no notified name service in step S108, the bibliographic information service of the MFP 300-1 determines that there is a notification destination in the name service notification destination in FIG. 17 and in step S110. If so, the name information is transmitted to the name service notification destination multifunction device (corresponding to the multifunction device 300-2 in the system configuration diagram of FIG. 1) held in the RAM 302. That is, it is processing for transmitting image forming apparatus information for specifying the first image forming apparatus to the second image forming apparatus in order to notify that the print data has been stored in the first image forming apparatus.

  The name information transmitted here identifies the print data creation user name (ie, user identification information) extracted in step S103, the model name of the printer driver used to create the print data, and the print data storage location. The IP address (host name) of the own device is included.

  As described above, when there is a notification destination in step S110 (for example, when the first user prints), name information is transmitted to the multifunction device 300-2 of the name service, but when there is no notification destination in step S110 (for example, When the same user prints using the same model printer driver), the name information is not transmitted to the name service MFP 300-2, and the communication load is reduced. Decrease.

  When the MFP 300-2 has the function of the bibliographic information server of the conventional print system, information (print name, etc.) for identifying the print data every time print data is received, and information about the print data such as the storage location. It must be transmitted to the multifunction device 300-2 (every time), and when a conventional print system is applied, the communication load is high. On the other hand, in the present embodiment, communication can be reduced, and printing can be executed from a desired multifunction device by a print system in which print data is stored in the multifunction device.

  In step S112, the name service of the multifunction device 300-2 receives name information from the bibliographic information service of the multifunction device 300-1 in step S111. That is, it is processing for receiving image forming apparatus information from the first image forming apparatus.

  In step S113, the name service of the MFP 300-2 has already created a name information file as shown in FIG. 16 managed by the print data creation user name of the name information acquired in step S112 and the model name of the printer driver. Check if it is.

  Here, FIG. 16 will be described. FIG. 16 shows an example of the name information file.

  The name information file includes a print data creation user name and a printer driver model name. The file also stores the IP address (host name) of the multifunction machine for identifying the storage location of the received print data of the received name information.

  The name information file may be of any structure as long as it can be determined by the user name and the model name. For example, it may be managed in a database or table. In the case of different users or different model names, the name information file is generated with a different file name.

  In step S114, the name service of the MFP 300-2 checks the presence or absence of the name information file in step S113, and if it is determined that the name information file of the corresponding user name and model name already exists, The process proceeds to S116, and if it is determined that there is no name information file for the corresponding user and model name, the process proceeds to step S115.

  In step S115, the name service of the MFP 300-2 generates a file name based on the user name and model name determined to have no corresponding name information file in step S114, and the name information file as shown in FIG. Create a new. That is, image forming apparatus information is stored for each user identification information.

In step S116, the name service of the MFP 300-2 receives the print received in step S112 on the last line of the name information file whose existence has been confirmed in step S114 or the name information file newly created in step S115. An IP address (host name) for identifying the data storage destination is added. That is, it is a process of storing image forming apparatus information.
In step S117, the name service of the MFP 300-2 responds to the bibliographic information service of the MFP 300-1 with the name information addition result of Step S116.
In step S118, the bibliographic information service of the multifunction device 300-1 receives the name service addition result response of the multifunction device 300-2 in step S117.

  In step S119, if the bibliographic information service of the MFP 300-1 determines that the name information is correctly added in the addition response result received in step S118, the process proceeds to step S120, and the name information is added. If it is determined that the process has failed, the process proceeds to step S110.

  In step S120, the bibliographic information service of the multifunction peripheral 300-1 determines that the name information is correctly added in step S119, the notification destination name service (composite name) is added to the notified name service list as shown in FIG. The IP address of the machine 300-2 is added, and the process returns to step S110. If it is determined in step S110 that the notification of name information has been completed for all notification destination name services, the process ends. That is, the second image forming apparatus information that has transmitted the image forming apparatus information is stored as the transmitted second image forming apparatus. Further, the transmitted second image forming apparatus (transmitted information) is shown in FIG.

  In steps S106 to S111, the second image formation that has not been transmitted without transmitting the image forming apparatus information that identifies the first image forming apparatus to the transmitted second image forming apparatus. In this process, image forming apparatus information for specifying the first image forming apparatus is transmitted to the apparatus. This can prevent duplication of transmission.

  FIG. 7 is a flowchart of the authentication process in the present embodiment. FIG. 8 is a flowchart of name information acquisition and list acquisition processing according to this embodiment. Each process will be described together with the number of steps.

  In step S200, the authentication program of the MFP 300-3 displays a screen as shown in FIG. 12 on the operation unit 308, and acquires card ID information in the IC card held over the card reader 319.

  Here, FIG. 12 will be described. FIG. 12 is a diagram illustrating an example of the authentication screen. The authentication screen is stored in the HDD 304.

  On the authentication screen, it is possible to switch between IC card authentication and keyboard authentication. At the time of keyboard authentication, a soft keyboard is displayed on the operation unit 308, and a user name and password can be input. This authentication screen is a screen for IC card authentication.

  In step S201, the authentication program of the MFP 300-3 acquires user information (user name, etc.) associated with the card ID acquired in step S200 from the user information table as shown in FIG. To do. In this embodiment, the user information table is configured to be stored in the HDD 304 of the multifunction peripheral. However, an IC card authentication request command including the card ID is transmitted to an authentication server that manages the card ID and the user information in association with each other. User information may be acquired.

  Here, FIG. 15 will be described. FIG. 15 is a diagram illustrating an example of the user information table. A user information table is stored in the HDD 304.

  In the user information table, a user name, an e-mail address, and a card ID are managed in association with each user, and user information of a plurality of users is stored. In addition, not only a user name, an e-mail address, and card ID, but the structure which memorize | stores the authority information etc. for using a multifunction machine may be sufficient.

In step S202, the authentication program of the multifunction device 300-3 performs login processing (use permission) to the multifunction device 300-3 based on the user information acquired in step S201.
In step S203, the authentication program of the multifunction machine 300-3 notifies the login user information to the printing program of the multifunction machine 300-3.

  In step S204, the printing program of the MFP 300-3 acquires the login user information notified by the authentication program of the MFP 300-3 in step S203.

  In step S205, the printing program of the MFP 300-3 stores a name service stored in advance based on the login user information acquired in step S204 and the model name of the own apparatus (for example, MFP 5050) acquired in advance. The MFP 300-2 (the default MFP (primary) that requests acquisition) transmits a request for acquiring the login user name information (print data storage location information). If communication with the default MFP is not possible, an acquisition request is sent to the next MFP (secondary). In other words, this is a process of requesting the second image forming apparatus for the image forming apparatus information that is the storage location of the print data.

Step S205 will be described in detail with reference to FIG.
FIG. 20 is a flowchart for determining a multifunction device of a name service that is an inquiry destination of name information (print data storage location information) in the present embodiment.

  In step S <b> 2051, the printing program of the multifunction machine 300-3 acquires setting information for determining a name service multifunction machine as illustrated in FIG. 17 which is set in advance. Note that the more detailed setting information of FIG. 17 is shown in FIG. 21, and will be described with reference to FIG.

  In step S2052, it is determined whether or not the own apparatus operates as a name service multifunction peripheral. Whether or not the own device operates as a name service multifunction device is determined by whether or not the multifunction device of the primary name service (name service 1) shown in FIG. 17 is the same as the IP address of the own device. The determination as to whether the own device operates as a name service multifunction device may be made based on whether or not a communication port for operating as a name service is open in the own device. Further, it may be determined whether or not the own apparatus operates as a name service MFP by turning on / off the name service setting. When it is ON, it is determined that the own device is a name service, and when it is OFF, it is determined that the own device is not a name service.

If the printing program of the MFP 300-3 determines that the own apparatus is a setting for the MFP of the name service based on the name service setting acquired in S2501, the process proceeds to Step S2503, where the own apparatus performs the name service. If it is determined that the service is not a multifunction peripheral, the process advances to step S2054.
By determining whether or not the own device is a name service, unnecessary communication can be prevented and the communication load can be reduced.
In step S2053, if the printing program of the MFP 300-3 determines that the self apparatus is a name service MFP in step S2052,

Based on the login user information acquired in step S204 and the model name of the own device (for example, MFP 5050) acquired in advance, name information (print data storage location information) stored in the own device is acquired in advance. To do.

  In step S2054, as described above in step S205, the printing program of the MFP 300-3 is based on the login user information acquired in step S204 and the model name of the own apparatus (for example, MFP 5050) acquired in advance. According to the setting information for determining the name service MFP acquired in step S2051, the name service MFP 300-2 (default MFP (primary, for example, name service 1) that requests acquisition) An acquisition request for the name information (print data storage location information) of the login user is transmitted. If communication with the default MFP is not possible, an acquisition request is sent to the next MFP (secondary, for example, name service 2).

  When notifying the name information in step S111, the name services 1 to 10 in FIG. 17 are notified, but when requesting the acquisition of name information in step S2054, the name service 1 is configured. .

  In step S206, the name service of the MFP 300-2 receives the name information acquisition request transmitted by the printing program of the MFP 300-3 in step S205. That is, it is a process of receiving a request for image forming apparatus information from the first image forming apparatus.

  In step S207, the name service of the MFP 300-2 confirms the presence or absence of a name information file as shown in FIG. 16 based on the user name and model name included in the name information acquisition request received in step S206. The user name information (print data storage location information) is searched.

More specifically, the name information received in step S206 is acquired in order to acquire the storage location information of the user's print job that can be printed by the multifunction peripheral in which the printing program of the multifunction peripheral 300-3 that is the request source is operating A name information file as shown in FIG. 16 is searched based on the user name and model name included in the request. The file name of the name information file includes a user name and a model name, and the name information file is searched by comparing the file name with the user name and model name included in the name information acquisition request. In this embodiment, the model name is used. However, since printing may be possible even if the model is different, it may be a printer group indicating a group of printers that are printable printer groups.
Further, the information of the name information file shown in FIG. 16 may be managed by a database instead of individual files.

  Then, the name information (print data storage destination information such as an IP address) of the destination multi-function peripheral that stores the print job that can be printed by the user and stored in the searched name information file is acquired.

  In step S208, the name service of the MFP 300-2 responds to the print program of the MFP 300-3 with the name information (print data storage destination information) searched in Step S207. That is, in accordance with a request for image forming apparatus information, a list of image forming apparatus information that is a storage destination of print data that can be printed by the first image forming apparatus is transmitted to the first image forming apparatus. Further, the image forming apparatus information list is transmitted in accordance with the user identification information of the user who has logged into the first image forming apparatus.

  In step S209, the printing program of the MFP 300-3 receives the name information transmitted by the name service of the MFP 300-2 in Step S208. The received name information is stored in the RAM 302.

  In step S210, if it is determined that the name information received in step S209 includes the print data storage destination of the logged-in user other than its own device, the printing program of the MFP 300-3 proceeds to step S211. If it is determined that there is no print data storage destination for the user other than the user apparatus, the process proceeds to step S218. The above step S210 will be described in more detail. The print data storage destination IP address information acquired in step S209 is compared with the IP address of the own device acquired in advance when the application is started, and the IP address information acquired from the name service of the MFP 300-2 If it is determined that a device other than the IP address of the device is included, the process proceeds to step S211. If it is determined that an IP address other than the own device is not included, the process proceeds to step S218.

  In step S211, if it is determined in step S210 that there is a print data storage destination for the logged-in user other than the self apparatus, the print program of the MFP 300-3 becomes a bibliographic information service corresponding to the print data storage destination. A bibliographic information list acquisition request including the login user name and the model name of the own device is transmitted to the multifunction device 300-1. That is, it is a process of requesting a list of print data from each image forming apparatus corresponding to the received image forming apparatus information.

  In step S212, the bibliographic information service of the multifunction machine 300-1 receives the bibliographic information list acquisition request transmitted by the printing program of the multifunction machine 300-3 in step S211.

In step S213, the bibliographic information service of the multifunction peripheral 300-1 receives the request for acquiring the bibliographic information list including the user name and model name received in step S212, as shown in FIG. 14 corresponding to the received user and model name. Search bibliographic information files.
In step S214, the bibliographic information service of the MFP 300-1 creates a bibliographic information list with the bibliographic information searched in step S213.

  In step S215, the bibliographic information service of the multifunction device 300-1 transmits the bibliographic information list created in step S214 to the printing program of the multifunction device 300-3. That is, it is a process of receiving a list of image forming apparatus information that is a storage location of print data from the second image forming apparatus.

  In step S216, the printing program of the multifunction machine 300-3 acquires the bibliographic information list transmitted by the bibliographic information service of the multifunction machine 300-1 in step S215. That is, it is a process of receiving a list of print data from each image forming apparatus that has requested.

  In step S217, the printing program of the MFP 300-3 deletes the storage location of the print data that has received the bibliographic information list as received from the name information stored in the RAM 302, and returns the process to step S210. In step S210, if there is a print data storage destination for which bibliographic information has not been acquired in the name information, steps S211 to S217 are repeated.

  In step S218, if it is determined in step S210 that there is no print data storage destination in which the bibliographic information is not acquired in step S210, the printing program of the MFP 300-3 displays the bibliographic information of the login user in its own device. get. That is, it is a process of requesting a list of print data from the first image forming apparatus which is its own apparatus.

  In step S219, the printing program of the MFP 300-3 merges (for example, combines) the bibliographic information lists acquired in steps S217 and S219, and displays a print data list screen as shown in FIG.

Here, FIG. 13 will be described. FIG. 13 is a diagram illustrating an example of a print data list screen. The print data list screen is stored in the HDD 304.
The print data list screen displays the merged bibliographic information list as a list of print data on 1301. In 1301, print data can be selected.

  In addition, the print data list screen includes a delete 1302 button and a print start button 1303 so that the print data selected in 1301 can be deleted or the print can be started (print instruction).

  FIG. 9 is a flowchart of a print instruction and print data transmission process in the present embodiment. Each process will be described together with the number of steps.

  In step S300, an arbitrary print data 1301 is selected from the print data list screen as shown in FIG. 13 displayed by the printing program of the multifunction machine 300-3 in step S219 by the user who has logged in to the multifunction machine 300-3. After that, the press of the print start 1303 is accepted and a print instruction for the selected print data is issued.

  In step S301, the printing program of the MFP 300-3 is selected in step S300, acquires the request instructed to print, and is included in the bibliographic information of the selected print data from the bibliographic information list acquired in step S126. A name (storage destination) 1404 is acquired.

  In step S302, if the printing program of the MFP 300-3 determines that there is host name (storage destination) information of the print instruction destination acquired in step S301, the process proceeds to step S303, and there is no print instruction destination. If it is determined, the process proceeds to step S317.

  In step S303, when it is determined in step S302 that there is a print instruction destination in step S302, the printing program of the multifunction peripheral 300-3 determines whether the print instruction destination of the selected print data is the self apparatus. If it is determined that the print instruction destination of the selected print data is the own apparatus, the process proceeds to step S314. If it is determined that the print instruction destination of the selected print data is not the own apparatus, the process proceeds to step S304. Proceed with the process.

  In step S304, if the print program of the MFP 300-3 determines that the print instruction destination of the print data of the bibliographic information selected in step S303 is not its own device, the host name (storage destination) acquired in step S301. ) To send a print instruction request including the file name 1402 in the bibliographic information of the selected print data. If a plurality of print data stored in the same host name (storage destination) are selected in step S301, a print instruction request including the file names of all corresponding print data is transmitted. In other words, this is a process of making a print request to the image forming apparatus corresponding to the received image forming apparatus information. Further, this is a process of making a print request to the image forming apparatus in which the print data selected from the print data list is stored. As a result, the communication load can be reduced.

  In step S305, the bibliographic information service of the multifunction device 300-1 receives the print instruction request transmitted by the printing program of the multifunction device 300-3 in step S304.

  In step S306, the bibliographic information service of the multifunction peripheral 300-1 acquires the corresponding print data from the HDD 304 based on the file name included in the print instruction request received in step S305.

  In step S307, the bibliographic information service of the MFP 300-1 transmits the print data acquired in Step S306 to the MFP 300-3 using, for example, the FTP protocol.

In step S308, the printing program of the multifunction peripheral 300-3 receives the print data transmitted by the bibliographic information service of the multifunction peripheral 300-1 in step S307.
In step S309, the printing program of the MFP 300-3 prints the print data received in step S308.

  In step S310, the bibliographic information service of the multifunction peripheral 300-1 determines that there is print data that has not been transmitted to the multifunction peripheral 300-3 among the file names included in the print instruction request received in step S305. If YES in step S306, the process advances to step S306 to repeat the processes in steps S306 to S310 while there is print data that has not been transmitted to the MFP 300-3. If it is determined that there is no print data that has not been transmitted to the MFP 300-3, the process advances to step S311.

  In step S311, the bibliographic information service of the MFP 300-1 determines that there is print data that has not yet been transmitted in step S310, and the print instruction including the file name for the print program of the MFP 300-3. Send the result.

  In step S312, the printing program of the multifunction peripheral 300-3 receives the print instruction result transmitted by the bibliographic information service of the multifunction peripheral 300-1 in step S311 and advances the process to step S316.

  In step S313, if the print instruction destination is determined to be the self apparatus in step S303, the printing program of the MFP 300-3 adds the file name 1402 included in the bibliographic information of the print data selected by the user in step S300. Applicable print data is acquired from the own apparatus. That is, when print data selected from the print data list is stored in the first image forming apparatus, the print data is acquired from the first image forming apparatus.

  In step S314, the printing program of the MFP 300-3 prints the print data acquired in step S313. That is, it is a process for printing the received print data in accordance with the print request.

  In step S315, if it is determined that the print data not yet printed out of the print data selected in S300 exists in the MFP 300-3, the process proceeds to step S313. While there is print data that has not been printed yet, the processing from step S313 to step S315 is repeated. If it is determined that there is no print data that has not been printed yet, the process proceeds to step S316.

  In step S316, the printing program of the multifunction peripheral 300-3 determines in step S301 the multifunction peripheral that has obtained the print instruction result in step S312 and the own apparatus (multifunction peripheral) that has completed the print instruction in steps S313 to S315. It deletes from the acquired storage destination information (it removes from the object of a printing instruction | indication destination), and returns a process to step S302. While it is determined in step S302 that there is a print instruction destination, steps S303 to S316 are repeatedly performed. If it is determined that there is no print instruction destination, the process proceeds to step S317.

  In step S317, if it is determined that there is no print instruction destination in step S302, the printing program of the multifunction peripheral 300-3 displays an unselected print data list screen that has not been selected by the user in step S300.

  FIG. 10 is a flowchart of the deletion instruction in this embodiment. FIG. 11 is a flowchart of name information deletion processing according to this embodiment. Each process will be described together with the number of steps.

  In step S400, the user who has logged in to the multifunction machine 300-3 performs arbitrary printing from the print data list screen as shown in FIG. 13 displayed by the printing program of the multifunction machine 300-3 in step S219 or step S317. After the data 1301 has been selected, pressing of the delete 1302 is accepted and an instruction to delete the selected print data is given.

  In step S401, as in step S301, the printing program of the MFP 300-3 receives the request selected by the user in step S400 and instructed to be deleted, and receives the selected print data from the bibliographic information list acquired in step S126. A host name (storage destination) 1404 included in the bibliographic information is acquired.

  In step S402, if it is determined in step S401 that there is at least one deletion instruction destination host name (storage destination) information, the printing program of the MFP 300-3 proceeds to step S403, and the deletion instruction destination is determined. If it is determined that there is not, the process proceeds to step S415.

  In step S403, the printing program of the MFP 300-3 determines that there is a deletion instruction destination in step S402, and if it is determined that the deletion instruction destination of the selected print data is the own apparatus, step S411. If it is determined that the deletion instruction destination of the selected print data is not the own apparatus, the process proceeds to step S404.

  In step S404, if the print program of the MFP 300-3 determines that the print data deletion instruction destination selected in step S403 is not its own device, the print program of the MFP 300-3 performs the process for the host name (storage destination) acquired in step S401. Then, a delete instruction request including the file name 1402 in the bibliographic information of the selected print data is transmitted. If a plurality of print data stored in the same host name (storage destination) are selected in step S401, a delete instruction request including the file names of all corresponding print data is transmitted.

  In step S405, the bibliographic information service of the multifunction device 300-1 receives the delete instruction request transmitted by the printing program of the multifunction device 300-3 in step S404.

  In step S406, the bibliographic information service of the MFP 300-1 acquires the bibliographic information file of the corresponding print data as shown in FIG. 14 based on the file name included in the deletion instruction request received in step S405.

  In step S407, the bibliographic information service of the MFP 300-1 changes the status 1401 in the bibliographic information file for which the deletion instruction request has been acquired in step S406 to deleted. That is, it is a process for setting the print data in a deleted state.

  In step S408, the bibliographic information service of the MFP 300-1 includes print data whose status 1401 in the bibliographic information file has not been changed to deleted among the file names included in the deletion instruction request received in step S405. If it is determined that there is print data, the process proceeds to step S406, and while there is still print data in which the status 1401 in the bibliographic information file has not been changed to deleted, the processes from step S406 to step S408 are repeated. If it is determined that there is no print data whose status 1401 in the bibliographic information file has not been changed to deleted, the process proceeds to step S409.

  In step S409, the bibliographic information service of the MFP 300-1 determines that there is print data in which the status 1401 in the bibliographic information file has not been changed to deleted yet in step S408. The delete instruction result is transmitted to the print program, and the process proceeds to step S416.

  In step S410, the printing program of the MFP 300-3 receives the delete instruction result transmitted by the bibliographic information service of the MFP 300-1 in step S409, and advances the process to step S414.

  In step S411, the printing program of the MFP 300-3 determines that the deletion instruction destination is the self apparatus in step S403, and sets the file name 1402 included in the bibliographic information of the print data selected by the user in step S400. The corresponding bibliographic information file is acquired from the own device.

  In step S412, the printing program of the MFP 300-3 changes the status 1401 in the bibliographic information file for which the deletion instruction request has been acquired in step S406 to deleted.

  In step S413, the printing program of the MFP 300-3 determines that there is print data in which the status 1401 in the bibliographic information file has not been changed to deleted in the own apparatus among the print data selected in S400. If so, the process proceeds to step S411, and the process from step S411 to step S413 is repeated while there is still print data in which the status 1401 in the bibliographic information file has not been changed to deleted. If it is determined that there is no print data whose status 1401 in the bibliographic information file has not been changed to deleted, the process proceeds to step S414.

  In step S414, the printing program of the MFP 300-3 stores the deletion instruction destination that has acquired the deletion instruction result in step S410, and the storage destination information acquired in step S401 for the own apparatus that has been deleted in steps S411 to S413. From the list (removed from the deletion instruction target), and the process returns to step S402. While it is determined in step S402 that there is a deletion instruction destination, steps S403 to S314 are repeatedly performed. If it is determined that there is no deletion instruction destination, the process proceeds to step S416.

  In step S415, if it is determined in step S402 that there is no deletion instruction destination, the printing program of the MFP 300-3 displays an unselected print data list screen that was not selected by the user in step S400.

  In step S416, the bibliographic information service of the multifunction device 300-1 determines whether printable data of the currently logged-in user still exists in the multifunction device 300-1 after transmitting the deletion result in step S409. . If it is determined that there is still printable data, the process ends. If it is determined that there is no printable data for the currently logged-in user, the process proceeds to step S417.

  In step S417, if the bibliographic information service of the MFP 300-1 determines that there is no printable data of the currently logged-in user in step S416, a list of notified name services as shown in FIG. get.

  In step S418, the bibliographic information service of the MFP 300-1 determines whether there is the MFP 300-2 of the name service notified as the print data storage destination of the user who has requested deletion. If the bibliographic information service of the MFP 300-1 determines that there is at least one name service that has been notified, the process proceeds to step S419, and there is no name service to be notified. If it is determined, it is determined that there is no need to notify deletion, and the process is terminated.

In step S419, the bibliographic information service of the MFP 300-1 corresponds to the name service determined to have the notified name service in Step S418 (corresponding to the MFP 300-2 in the system configuration diagram of FIG. 1). Name information deletion notification. The name information deletion notification transmitted here includes the user name of the currently logged-in user, the model name of the own device acquired in advance, and the IP address (host name) of the own device. That is, it is a process of notifying the second image forming apparatus of a print data deletion notification.
Steps S416 to S419 are processing for notifying deletion notification when there is no printable print data in the first image forming apparatus.

  In step S420, the name service of the multifunction peripheral 300-2 receives the name information deletion notification transmitted by the bibliographic information service of the multifunction peripheral 300-1 in step S419. That is, it is a process of receiving a print data deletion notification from the first image forming apparatus.

  In step S421, the name service of the MFP 300-2 confirms (searches) a name information file as shown in FIG. 16 corresponding to the user name and model name included in the name information deletion notification received in step S420. .

  In step S422, the name service of the MFP 300-2 determines that the storage destination IP address (host name) included in the name information deletion notification received in step S420 exists in the name information file confirmed in step S421. If so, the process proceeds to step S423. If it is determined that the storage destination IP address does not exist, the process proceeds to step S424.

  If it is determined in step S423 that the name service of the MFP 300-2 has the storage destination IP address (host name) included in the deletion notification in step S422, the corresponding IP address (host name) is set in step S421. Delete it from the name information file confirmed in. That is, in accordance with the deletion notification, the image forming apparatus information of the first image forming apparatus that has received the deletion notification is deleted.

  In step S424, the name service of the MFP 300-2 determines that there is no corresponding storage destination IP address in step S422, and after deleting the storage destination IP address in step S423, the MFP 300-2 deletes the storage destination IP address. The name information deletion result is transmitted to the bibliographic information service of -1.

  In step S425, the bibliographic information service of the MFP 300-1 receives the name information deletion result transmitted by the name service of the MFP 300-2 in Step S424.

  In step S426, the bibliographic information service of the MFP 300-1 advances the process to step S427 when it is determined that the deletion of the name information is correctly performed based on the deletion result of the name information received in step S425. If it is determined that the name information has not been deleted, the process proceeds to step S418.

  In step S427, the bibliographic information service of the MFP 300-1 determines that the name information has been notified from the notified name service list of FIG. 18 acquired in step S417 when it is determined in step S426 that the name information has been correctly deleted. The service is deleted, and the process proceeds to step S418. In step S418, while it is determined that there is still a notified name service, the processing from step S419 to step S427 is repeatedly performed, and when it is determined that there is no notified name service, the process is terminated. That is, in accordance with the deletion notification, the image forming apparatus information of the second image forming apparatus notified of deletion from the transmitted information is deleted.

  Print data exists by properly deleting name information from the name information file stored in the name service MFP and deleting it from the list of notified name services stored in the bibliographic information service MFP. Since unnecessary communication is not performed when not, printing can be executed from a desired printer with a reduced communication load.

  In the present embodiment, the name information deletion flow described in steps S416 to S427 is described between the bibliographic information service of the MFP 300-1 and the name service of the MFP 300-2. Similarly, in the print program No. -3, after the status 1401 in the bibliographic information file corresponding to the print data held in the own apparatus is changed to deleted, the name information described in steps S416 to S427 is deleted. To do.

  Further, in this embodiment, the status 1401 in the bibliographic information file is changed to deleted or a name information deletion notification is performed according to a deletion instruction from the user, but after a certain period of time has elapsed from the generation time of the print data For print data whose status 1401 in the bibliographic information file has not been deleted by a user instruction, the status 1401 in the bibliographic information file is automatically changed to deleted at the timing when the storage period has passed. Is also possible. It goes without saying that even when automatic deletion is performed, the flow of deletion of name information described in steps S416 to S426 described in the present embodiment is performed.

  In this embodiment, in response to a deletion instruction from the user, the status 1401 in the bibliographic information file is only changed to deleted. However, the print data itself whose status 1401 has been deleted at a regular time or a regular interval. Needless to say, it is deleted from the HDD 304.

  In the present embodiment, a printing system using a multi-function peripheral is used, and print data is designated and printed using the operation unit of the multi-function peripheral. However, a list of print data such as a laser beam printer may be displayed. A printing system including a printer with an operation unit (display unit) that cannot be used may be used.

In this case, when the user logs in to the printer and obtains name information from the multifunction device of the name service, a print data list (bibliographic information list) is obtained from the multifunction device corresponding to the name information and corresponds to the bibliographic information. Make a print request to a multifunction device. Alternatively, if name information is obtained from a multifunction device of the name service without obtaining a print data list, the print data corresponding to the logged-in user is printed to the multifunction device corresponding to the name information obtained for the print request so as to be collectively printed. A request is made (all print requests for the login user's print data are made to each multifunction device in which the login user's print data is stored).
Further, the description has been made on the premise of the multifunction peripheral, but it can be realized as long as it is not a multifunction peripheral and can store print data.

  Further, as described above, in the description of the present embodiment, the multifunction machine 300-1, the multifunction machine 300-2, the multifunction machine 300-3, and the multifunction machine have been described separately. 1 may have the function of the MFP 300-3, and the MFP 300-1 may have the function of the MFP 300-2 and the function of the MFP 300-3. . Further, the MFP 300-3 may have the functions of the MFP 300-1 and the MFP 300-2.

  As described above, according to the present embodiment, a list of image forming apparatuses that store print data is managed, and a print request is made to the image forming apparatus according to the list, so that the print data stored in the image forming apparatus can be formed into a desired image. It is possible to reduce the communication load when printing from the apparatus.

  Also, considering the communication load, the print data is stored in the multifunction peripheral (image forming apparatus) and the print data stored in each multifunction peripheral (image forming apparatus) without arranging a server for storing the print data. Can be printed from a desired image forming apparatus.

  In addition, even if the user prints print data on a specific multifunction device, it is possible to store the data on the HDD of the multifunction device. Therefore, it is necessary to install an external server as in the conventional pull print system. It becomes easy to operate.

  Even if no server is installed externally, the storage location of the data printed by the user is notified to the MFP and managed, and when printing, the login user prints from the MFP managing the storage location. Since it is a mechanism for acquiring the data storage destination, when a multifunction device that is normally used is used by another user and cannot be used, it is possible to output from another usable multifunction device.

  In addition, since broadcast communication is not used for storage location notification, operation beyond the segment is possible. In addition, since it is only necessary to notify not all MFPs but only MFPs that manage storage destinations, it is possible to provide a mechanism that does not require periodic maintenance of all MFPs.

Furthermore, instead of notifying the storage location every time print data is received from the client PC, if the print data has already been received from the same user, the storage location is not notified again, so the network load is reduced. Is possible.
It should be noted that the configuration and contents of the various data described above are not limited to this, and it goes without saying that the various data and configurations are configured according to the application and purpose.
