Description

  The present invention relates to a technique for performing printing in cooperation with a plurality of image forming apparatuses.

  2. Description of the Related Art Conventionally, there is a printing apparatus (hereinafter referred to as a multifunction machine) having a plurality of functions such as a printing function, an image reading function, a copying function, and a communication function. By sharing the print data information temporarily stored in this multi-function peripheral between other multi-function peripherals connected to the network, the user can select a specific multi-function peripheral (multi-function peripheral in which print data is temporarily stored). Output of print data from a desired multifunction device is possible instead of output from the printer.

  Further, in recent years, in a printing system that outputs print data accumulated in each multifunction peripheral from a desired multifunction peripheral, the output is performed from the desired multifunction peripheral without installing a server for managing a plurality of multifunction peripherals. A mechanism is considered.

  For example, in Patent Document 1, when print data is stored in a multifunction device, the multifunction device in which the print data is stored is managed by another multifunction device (name service multifunction device) that is executing a name service. Then, when the user logs in to the desired multifunction device, the name service multifunction device is inquired about information (name information) of the multifunction device in which the user's print data is stored, and according to the name information obtained as a result of the inquiry. The print data list is inquired of the multifunction peripheral in which the print data is stored, and the desired print data can be printed by the desired multifunction peripheral.

  A current multifunction device is equipped with a function of shifting to a power saving mode and suppressing power consumption when no user operation or data communication between networks occurs for a certain period of time.

  However, when a printing system such as that disclosed in Patent Document 1 is constructed, the MFP does not shift to the power saving mode, or even if it shifts to the power saving mode, it immediately shifts to the normal operation mode. There was a problem that it did not lead to the transformation.

  For example, in the printing system of Patent Document 1, when a user selects print data on a multifunction peripheral and acquires name information for displaying a list of accumulated print data, the multifunction peripheral corresponding to the name information is displayed. Inquire about whether there is print data at once. Therefore, even if the MFP that has received the inquiry has just shifted to the power saving mode, it returns from the power saving mode to the normal operation mode.

  In other words, even though it has not been decided whether to actually print, communication between the multifunction devices occurs, and the multifunction device that has shifted to the power saving mode may be restored to uselessness. The effect of the mode could not be demonstrated.

  As a mechanism in the power saving mode of the MFP, there is Patent Document 2, but in Patent Document 2, it is necessary to install an external device and manage a document list stored in the external device. There is a problem that it is difficult to apply in an environment where a dedicated server is not required. In addition, when trying to build a mechanism to execute printing from a desired multifunction device, it is necessary to change the inquiry destination to an external device instead of making an inquiry to the multifunction device in which print data is stored in the power saving mode. For this reason, there is a problem that it cannot withstand operation.

  The present application has been made in view of the above-described problems, and an object thereof is to provide a technique capable of operating the system efficiently.

In order to achieve the above object, a system according to the present invention comprises the following arrangement. That is,
A first image forming apparatus for storing print data and bibliographic information thereof; a second image forming apparatus for storing storage destination information indicating a storage destination for storing the print data; and printing based on the print data. A system including a third image forming apparatus,
The second image forming apparatus includes:
The identification information indicating the first image forming apparatus that is the storage destination indicated by the storage destination information, the identification information including the state of the first image forming apparatus, and the storage destination information are associated with each other and managed. Management means to
Transmission means for transmitting the identification information of the first image forming apparatus to the third image forming apparatus in response to a request from the third image forming apparatus;
The third image forming apparatus includes:
Receiving means for receiving the identification information from the second image forming apparatus;
Requesting means for requesting bibliographic information of print data stored in the first image forming apparatus that is not in a power saving state to the first image forming apparatus based on the identification information received by the receiving means;
Obtaining means for obtaining bibliographic information of print data stored in the first image forming apparatus in accordance with a request from the requesting means.

  According to the present invention, the system can be operated efficiently.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of a printing system including a client PC and a multifunction peripheral.

  In FIG. 1, a plurality of client PCs 200 and a plurality of multi-function peripherals are connected via a network 400 so that they can communicate with each other. The network 400 is, for example, a wired LAN, but other forms such as a wireless LAN can be used in addition to this, and a wired LAN and a wireless LAN can be used in combination.

  A printer driver is installed in the client PC 200. The printer driver can create print data based on data received from an application program (print application), and transmit the print data to the multi-function peripheral 300 (STORAGE).

  Upon receiving the print data, the MFP 300 (STORE) acquires the bibliographic information from the attribute information (user name or print data file name) included in the print data, and associates the bibliographic information with the print data. Save to HDD. When the bibliographic information and the print data are stored, the multi function device 300 (STORAGE) transmits to the multi function device 300 (NAME_SERVICE) that manages print data storage destination information (hereinafter referred to as name information) that is information indicating the storage destination. .

  In this embodiment, in order to provide a function for displaying a list of print data corresponding to the login user, the name information includes the user name for the print data and the IP address (or host name) of the MFP. It is out.

  The user goes to the desired multifunction device 300 (PRINT) and executes login (IC card authentication or authentication by inputting a user ID and password). As a result, the MFP 300 (PRINT) issues a name information acquisition request to the MFP 300 (NAME_SERVICE) that manages the name information, and acquires the name information. Here, the IP address of the multifunction peripheral (MFP 300 (NAME_SERVICE)) that is the name information acquisition request destination is stored in advance in each MFP 300, and when issuing an acquisition request, the IP address is used. The name information acquisition request destination is determined by referring to the name information.

  In accordance with the name information, the multifunction device 300 (PRINT) makes an inquiry to the multifunction device 300 (STORE), acquires bibliographic information for the user, and displays a list on the multifunction device 300 (PRINT). Then, a print request for print data corresponding to the bibliographic information selected by the user is transmitted to the multi-function peripheral 300 (STORAGE) in which the print data is stored. As a result, the MFP 300 (PRINT) acquires the print data to be printed from the MFP 300 (STORE), and executes printing on the MFP 300 (PRINT) to which the user has logged in.

  Here, when print data is accumulated across a plurality of multifunction devices 300, name information corresponding to each multifunction device is stored, so that the multifunction device 300 (PRINT) has a plurality of multifunction devices. An inquiry is made to 300 (STORAGE) to obtain bibliographic information.

  This is an outline of normal printing processing. In the present embodiment, when there is a power saving mode MFP 300 (STORAGE), the inquiry to the MFP 300 (STORAGE) is prohibited (suppressed). To control. In this case, since bibliographic information cannot be acquired, the MFP 300 (PRINT) is configured to display information (hosts) related to the MFP 300 whose inquiry is prohibited (suppressed) in a list.

  Note that a printing application is installed in the multi-function apparatus 300 as one of application programs. Then, by switching the setting of the print application, the multifunction peripheral 300 can switch the roles of STORE (storage function), NAME_SERVICE (name service function), and PRINT (print function). Alternatively, the multi function device 300 may execute the roles of all of STORE, NAME_SERVICE, and PRINT, or may execute the roles of any combination of STORE, NAME_SERVICE, and PRINT.

  FIG. 1 illustrates a configuration in which a list of bibliographic information of print data is acquired and then a print request for print data corresponding to the designated bibliographic information is made. However, the present invention is not limited to this. For example, when the user logs in to the MFP 300, the print data stored in a batch can be acquired and printed without displaying a list of bibliographic information of the print data. In this case as well, the print request is transmitted according to the name information of the MFP 300 that is not in the power saving mode.

  Hereinafter, the hardware configuration of the information processing apparatus applicable to the client PC 200 of FIG. 1 will be described with reference to FIG.

  FIG. 2 is a block diagram showing a hardware configuration of an information processing apparatus applicable to the client PC 200 shown in FIG.

  In FIG. 2, reference numeral 201 denotes a CPU, which comprehensively controls various components (devices and controllers) connected via a system bus 204. The ROM 202 or the external memory 211 stores a BIOS and OS that are control programs for the CPU 201, various programs necessary for realizing the functions executed by the client PC 200, and the like.

  Reference numeral 203 denotes a RAM that functions as a main memory, work area, and the like of the CPU 201. The CPU 201 implements various operations by loading a program necessary for executing the processing from the ROM 202 or the external memory 211 to the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 and a pointing device (not shown) such as a mouse. A video controller 206 controls display on a display device such as the LCD 210. In FIG. 2, the LCD 210 is used as the display device, but the present invention is not limited to this, and another display device may be used. These are used by the administrator as needed.

  A memory controller 207 controls access to the external memory 211. Examples of the external memory 211 include a hard disk (HDD) and a removable medium. The external memory 211 stores various data such as a boot program, various applications, font data, user files, edit files, and the like. The removable media includes a flexible disk (FD), a compact flash (registered trademark) memory connected to a PCMCIA card slot via an adapter, and the like.

  A communication I / F controller 208 is connected to and communicates with an external device via the network 400, and executes a communication control process in the network 400. For this communication control process, for example, a process using TCP / IP is possible.

  Note that the CPU 201 enables display on the LCD 210 by executing outline font development (rasterization) processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with an indicator such as a mouse cursor on the LCD 210.

  A program for realizing various processes described later is stored in, for example, the external memory 211 and is executed by the CPU 201 by being loaded into the RAM 203 as necessary. In addition, a definition file and various information tables used when executing this program are also stored in the external memory 211.

  Next, the hardware configuration of the controller unit that controls the multifunction peripheral 300 of FIG. 1 will be described with reference to FIG.

  In FIG. 3, reference numeral 316 denotes a controller unit, which is connected to a scanner 314 that functions as an image input device and a printer 312 that functions as an image output device. Further, the controller unit 316 inputs and outputs image data and device information by connecting to a LAN or a public line (WAN) (for example, PSTN or ISDN).

  In the controller unit 316, reference numeral 301 denotes a CPU, which is a processor that controls various components constituting the system via the system bus 309. A RAM 302 is a system network memory for the CPU 301 to operate, and is also a program memory for recording a program and an image memory for temporarily storing image data. A ROM 303 stores a system boot program and various control programs. A hard disk drive (HDD) 304 stores various programs for controlling the system, image data, and the like.

  An operation unit interface (I / F) 307 is connected to the operation unit 308, outputs image data to be displayed on the operation unit 308 to the operation unit 308, and controls the display thereof. The operation unit I / F 307 serves to transmit information (for example, user information) input by the user from the operation unit 308 to the CPU 301. The operation unit 308 includes a display unit having a touch panel, and various instructions can be given by a user pressing (touching with a finger or the like) a button displayed on the display unit.

  A network interface (I / F) 305 is connected to the network 400 to input / output data. A modem 306 is connected to a public line and inputs / outputs data such as FAX transmission / reception. Reference numeral 318 denotes an external interface (I / F) that accepts external inputs such as USB, IEEE 1394, printer port, and RS-232C. In the present embodiment, a card reader 319 for reading an IC card required for authentication is connected to the external I / F 318. The CPU 301 can control the reading of information from the IC card by the card reader 319 via the external I / F 318 to acquire the information.

  An image bus interface (I / F) 320 connects the system bus 309 and an image bus 315 that transfers image data at high speed, and is a bus bridge that converts a data structure. The image bus 315 is constituted by, for example, a PCI bus or IEEE1394. The following components are connected to the image bus 315.

  A raster image processor (RIP) 310 develops vector data such as a PDL code into a bitmap image. A printer interface (I / F) 311 connects the printer 312 and the controller unit 316, and performs synchronous / asynchronous conversion of image data. A scanner interface (I / F) 313 connects the scanner 314 and the controller unit 316 to perform synchronous / asynchronous conversion of image data.

  An image processing unit 317 corrects, processes, and edits input image data, and corrects the printer 312 and converts resolution of print data (output image data). In addition to this, the image processing unit 317 performs image data rotation and compression / decompression processing such as JPEG, MMR, and MH for binary image data for multi-valued image data.

  The scanner 314 illuminates an image of an original and scans it with a reading sensor (for example, a CCD line sensor), thereby converting it into an electrical signal as raster image data. The document is set on the tray of the document feeder, and when the user inputs a reading instruction from the operation unit 308, the CPU 301 gives an instruction to the scanner 314, and the feeder feeds the document sheet one by one and performs the reading operation of the document image. .

  The printer 312 converts raster image data into an image on a recording medium, and forms an image on the recording medium. The recording system realized by the printer 312 includes an electrophotographic system using a photosensitive drum and a photosensitive belt, and an ink jet system in which ink is ejected from a micro nozzle array to directly record an image on a sheet. It does not matter if it is a method. Execution of the printing operation is started by an instruction from the CPU 301. The printer 312 has a plurality of paper feed stages so that different paper sizes or different paper orientations can be selected, and has a paper cassette corresponding thereto.

  The operation unit 308 has an LCD display unit, and a touch panel sheet is pasted on the LCD. The operation unit 308 displays a system operation screen. When a key on the operation screen is pressed, the position information is displayed on the operation unit I / O. This is transmitted to the CPU 301 via F307. The operation unit 308 also includes hard keys such as a start key, a stop key, an ID key, and a reset key as various operation keys. Here, the start key is used, for example, when starting a document image reading operation. At the center of the start key, there are two color LEDs, green and red, which indicate whether or not the start key can be used. The stop key is used, for example, when stopping an operation in operation. The ID key is used when inputting the user ID of the user. The reset key is used when initializing settings related to the multifunction machine 300.

  The card reader 319 reads information stored in an IC card (for example, Sony FeliCa (registered trademark)) under the control of the CPU 301, and reads the read information via the external I / F 318. The CPU 301 is notified.

  With the above-described components, the multifunction peripheral 300 can transmit the image data read from the scanner 314 to the network 400 and print out the print data received from the network 400 by the printer 312. Also, the image data read from the scanner 314 can be faxed to the public line by the modem 306, and the image data received by fax from the public line can be output by the printer 312.

  Next, functions implemented by the client PC 200 will be described with reference to FIG. Note that the functions realized by the client PC 200 are realized, for example, when the CPU 201 reads out a program stored in the ROM 202 and executes it on the RAM 203.

  In the client PC 200, a printer driver 1210 is realized. The printer driver 1210 is called from various applications that operate on the client PC 200. The printer driver 1210 has a print data generation function 1211 as one of its functions. The print data generation function 1211 converts target application data (such as document data) into print data that can be printed by the multifunction device 300. The print data generation function 1211 prints based on the converted print data, or transmits the print data to the target multifunction device 300.

  Next, functions realized by the multifunction machine 300 will be described with reference to FIG. Note that the functions realized by the multifunction machine 300 are realized, for example, by the CPU 301 reading out a program stored in the ROM 303 and executing it on the RAM 302.

  In the MFP 300, a print application 1310 is realized. The print application 1310 can selectively execute various functions according to the role that the multifunction device 300 is responsible for. Here, the print application 1310 includes a print data management function 1311, a bibliographic information management function 1321, a print management function 1331, a host status management function 1341, and a name information management function 1351. These functions are switched between valid / invalid according to the values held in the operation mode (NAME_SERVICE / STORE / PRINT) in the setting information shown in FIG.

  FIG. 5 illustrates a function that is enabled / disabled in the print application 1310 when the MFP 300 is set to each of the NAME_SERVICE, STORE, and PRINT operation modes. Here, functions that are enabled are indicated by white rectangles, and functions that are disabled are indicated by shaded rectangles. In the following description, the multi-function device 300 operating in each mode is referred to as a multi-function device 300 (NAME_SERVICE), a multi-function device 300 (STORAGE), and a multi-function device 300 (PRINT).

  Hereinafter, each function realized by the print application 1310 will be described.

  The print data management function 1311 receives and manages print data transmitted from the client PC 200.

  The bibliographic information management function 1321 extracts the bibliographic information shown in FIG. 7 from the received print data and manages it in the multifunction device 300. Further, the bibliographic information management function 1321 notifies the multifunction device 300 (NAME_SERVICE) which is the storage destination of the name information including the user name and the IP address stored in the name information file shown in FIG. Search for a file using the user name as a key, and write the IP address to the file. The IP address may be acquired from the IP address of the transmission source that can be acquired on the communication protocol.

  The print management function 1331 acquires bibliographic information by user login to the MFP 300 or document list update by user operation. The bibliographic information corresponding to the logged-in user may be acquired from the own apparatus or may be acquired from the multifunction apparatus by communicating with the multifunction apparatus that manages the bibliographic information on the network. When the MFP 300 acquires the bibliographic information, the MFP 300 displays the acquired bibliographic information list as a log-in user's document list. When bibliographic information is selected in the document list, the MFP 300 controls printing of print data corresponding to the bibliographic information. To do.

  The host status management function 1341 transmits a host status change notification indicating a status change to the name service (multifunction device 300 (NAME_SERVICE)) when the self-device shifts from the ACTIVE state to the SLEEP state or from the SLEEP state to the ACTIVE state. . When the own apparatus operates as a name service, it receives a host status change notification notified from another multifunction device 300, and updates the host status information shown in FIG.

  The name information management function 1351 receives name information from the print application 1310 operating on the multifunction peripheral 300 on the network 400 and manages the update.

  The print application 1310 holds a value indicating one of the above-described three types of operation modes in accordance with the operation mode 601 of the setting information shown in FIG. This setting information is stored in the RAM 302, for example.

  When the operation mode 601 is [NAME_SERVICE], all the functions that can be realized by the print application 1310 are valid. Only when operating in the [NAME_SERVICE] mode, a function for receiving and managing name information from the MFP 300 (STORE) / (PRINT) and a host status change notification for managing the host status of each MFP 300 Function also works. The multifunction machine 300 (NAME_SERVICE) controls the multifunction machine 300 (STORE) / (PRINT) and realizes printing from a desired multifunction machine 300. A multifunction machine is installed in units of bases or floors. It is set to about one in the machine. Even in the [NAME_SERVICE] mode, the multifunction device 300 (NAME_SERVICE) operates with the functions realized in the [STORE] / [PRINT] mode.

  Note that the multifunction device 300 (NAME_SERVICE) has a redundant configuration, and it is possible to install (introduce) primary and secondary multifunction devices.

When the operation mode 601 is [STORAGE], functions other than the name information management function 1351 among the functions that can be realized by the print application 1310 are enabled. When operating in the [STORAGE] mode, a function of receiving print data from the client PC 200, storing it in the HDD 304, acquiring bibliographic information, generating name information, and notifying the MFP 300 (NAME_SERVICE); A function of acquiring a print data storage destination of the target user from the multifunction machine 300 (NAME_SERVICE) and constructing a document list and a function of executing printing according to a user's print instruction are executed. That is, when operating in the [STORAGE] mode, the MFP 300 (STORAGE) can also execute the function when operating in the [PRINT] mode. When the operation mode 601 is [PRINT], the print application 1310 is realized. Of the possible functions, only the print management function 1331 and the host status management function 1341 are enabled. In the [PRINT] mode, since there is no function for receiving print data from the client PC 200, a function for acquiring a print data storage destination of the target user from the MFP 300 (NAME_SERVICE) and constructing a document list , Only a function of executing printing according to a printing instruction from the user is provided. Here, the [PRINT] mode is a mode that is selected when a multi-function peripheral that is not equipped with a large-capacity storage device such as an HDD (cannot store print data) is installed.

  FIG. 6 shows an example of setting information (application settings) regarding the print application 1310.

  The operation mode 601 holds a value indicating a mode in which the print application 1310 operates, and here, a value indicating one of [NAME_SERVICE] / [STORE] / [PRINT] is set.

  The forced local print mode 602 holds a value indicating ON / OFF of a function for displaying a list of only documents stored in the own apparatus when a document is listed. The forced local print mode time 603 holds a value indicating a time zone in which the forced local print mode 602 is valid when the forced local print mode 602 is ON.

  Note that the forced local print mode means a predetermined print mode in which only the document (print data) of the target user stored in the apparatus is targeted for the document list. In the forced local printing mode, communication for acquiring bibliographic information stored in the MFP 300 on the network is not performed via the name service (that is, communication for acquiring bibliographic information is prohibited). Therefore, even if the multifunction device 300 (NAME_SERVICE) or the multifunction device 300 (STORAGE) is shifted to the power saving mode, it is possible to prevent a wasteful return.

  FIG. 7 shows an example of bibliographic information generated from attributes acquired when the print application 1310 receives print data.

  The bibliographic information is composed of data (text data) identified by the print data file name. That is, print data and bibliographic information are managed in association with each other, and bibliographic information is generated for the number of print data. As shown in FIG. 7, the bibliographic information includes information about print data such as a user name, a file name, a document name, and a time stamp.

  FIG. 8 shows an example of name information managed by the MFP 300 (NAME_SERVICE).

  The name information is composed of data (text data) identified by the user name of the print data. In other words, this name information is managed for each user, and thereby, it is possible to specify the MFP 300 in which the user's print data is stored. The name information includes at least the last storage date and time when the print data is stored in the MFP 300 and the IP address of the stored MFP as the information (host information) related to the MFP that functions as a host that stores the print data. It is out.

  FIG. 9 shows an example of host status information managed by the MFP 300 (NAME_SERVICE).

  This host status information is notified when the operation of the multifunction device 300 is changed, and the status (status) is managed for each multifunction device. The host status information includes the IP address and status for the multifunction machine.

  The status types are SLEEP and ACTIVE, where SLEEP indicates a power saving state and ACTIVE indicates a normal operating state (non-power saving state). When there are a plurality of modes (SLEEP / DEEP-SLEEP or the like) having different power saving levels in the power saving state, the state corresponding to that is stored.

  FIG. 10 shows an example of the document list screen of the target user displayed on the multifunction machine 300.

  In the document list screen 1000 of FIG. 10A, in addition to the document list 1001 that is a list of documents (bibliographic information of print data) managed by the MFP in the normal operation state, identification information of the MFP in the power saving state An example in which a list of 1002 is displayed is shown. Here, the identification information 1002 is displayed so as to be distinguishable from the document list 1001, and is grayed out in FIG.

  It should be noted that the identification information 1002 of the multifunction machine in the power saving state may be controlled to be displayed when an operation for obtaining a document list from another multifunction machine is performed by the user. Further, the identification information of the multifunction machine in the power saving state may be displayed on another screen (dialog). The identification information 1002 may be name information, for example.

  When any of the identification information 1002 is selected on the document list screen 1000 in FIG. 10A, a confirmation screen 1003 shown in FIG. 10B is displayed. This confirmation screen 1003 is a screen for confirming to the user that the power saving state is restored to the normal operation state because the identification information of the multifunction device in the power saving state is selected. When the OK button is pressed on the confirmation screen 1003, a document (print data) list inquiry is issued to the target multifunction peripheral in the power saving state, and the state transitions to the state of the document list screen 1100 in FIG.

  FIG. 11 shows the document list screen 1100 after the document list stored in the multifunction device in the power saving state (SLEEP state) is obtained on the target user's document list screen 1000 (FIG. 10) displayed on the multifunction device 300. Show. A new document list 1101 on the document list screen 1100 shows a list of documents (bibliographic information of print data) acquired from a power-saving multifunction peripheral, and is displayed in a selected state so that this list is preferentially printed. Is done.

  Note that the new document list 1101 may be displayed preferentially by displaying it at the top of the document list 1001. If print data is selected on the document list screen 1000 in FIG. 10, the newly acquired new document list 1101 is set to the selected state while maintaining the selected state.

  Next, processing executed in the printing system will be described with reference to the flowcharts of FIGS.

  FIG. 12 shows a process from when the print data is transmitted from the client PC 200 to the multifunction device 300 until the multifunction device 300 receives and stores the print data. Note that the processing in FIG. 12 is realized by the cooperation of the client PC 200, the multifunction device 300 (STORAGE), and the multifunction device 300 (NAME_SERVICE). The processing executed by the client PC 200 is realized, for example, by the CPU 201 reading out a program stored in the ROM 202 and executing it on the RAM 203. The processing executed by the multifunction machine 300 is realized, for example, by the CPU 301 reading a program stored in the ROM 303 and executing it on the RAM 302.

  In step S <b> 1201, the print data generation function 1211 in the printer driver 1210 in the client PC 200 is called when a print request is issued from various applications in the client PC 200. In response to this, the print data generation function 1211 generates print data by converting the target application data into printable data. Then, the print data generation function 1211 transmits the generated print data to the multi function device 300 (STORAGE).

  In step S <b> 1202, the print data management function 1311 of the print application 1310 in the multifunction peripheral 300 (STORAGE) receives print data transmitted from the client PC 200. In step S1203, the bibliographic information management function 1321 of the print application 1310 extracts bibliographic information (FIG. 7) from the received print data. In step S1204, the bibliographic information management function 1321 of the print application 1310 generates a bibliographic information file that is a file that holds the extracted bibliographic information, and stores the bibliographic information file in the HDD 304.

  In step S <b> 1205, the print data management function 1311 of the print application 1310 stores the received print data in the HDD 304 in association with the bibliographic information file stored in the HDD 304. In step S1206, the bibliographic information management function 1321 of the print application 1310 extracts a user name and a storage destination host from the extracted bibliographic information, generates name information of the target user, and transmits the name information to the multi-function peripheral 300 (NAME_SERVICE).

  Note that the information (IP address) of the MFP 300 (NAME_SERVICE) is stored in advance as setting information of the print application 1310. Therefore, the MFP 300 (NAME_SERVICE) is specified by referring to the setting information.

  In step S1207, the name information management function 1351 of the print application 1310 in the multifunction device 300 (NAME_SERVICE) receives name information transmitted from the multifunction device 300 (STORE). In step S1208, the name information management function 1351 of the print application 1310 acquires the user name from the received name information, and determines whether the name information file of the target user specified by the user name already exists in the apparatus. judge.

  If the name information file of the target user already exists as a result of the determination (YES in step S1208), in step S1212, the name information management function 1351 of the print application 1310 determines the last storage date and time of the target host in the target user name information file. Update to the current date and time. On the other hand, if the name information file of the target user does not exist as a result of the determination (NO in step S1208), in step S1209, the name information management function 1351 of the print application 1310 newly creates a name information file ( 8) is generated and saved (newly registered) in the HDD 304.

  In step S <b> 1210, the name information management function 1351 of the print application 1310 acquires storage destination host information indicating a host (multifunction peripheral) that is a storage destination from the received name information. Then, it is determined whether or not the target host information is included in the host status information (FIG. 9) managed in the own apparatus.

  If the host information is included as a result of the determination (YES in step S1210), in step S1212, the name information management function 1351 of the print application 1310 sets the last saved date and time of the target host (multifunction device) in the target user name information to the current date and time. Update to On the other hand, if the host information is not included as a result of the determination (NO in step S1210), in step S1211, the name information management function 1351 of the print application 1310 newly adds host information. Since the target host is the host (multifunction device) that has notified the name information, it is always in the ACTIVE state at this point, and in this case, ACTIVE is registered as the status.

  FIG. 13 shows a process for displaying a document list screen in the multifunction machine 300. The processing in FIG. 13 is realized by cooperation of the multifunction device 300 (PRINT), the multifunction device 300 (STORAGE), and the multifunction device 300 (NAME_SERVICE). The processing executed by the multifunction machine 300 is realized, for example, by the CPU 301 reading a program stored in the ROM 303 and executing it on the RAM 302.

  In step S1301, the print management function 1331 of the print application 1310 in the MFP 300 (PRINT) determines whether a document list update request has been issued. The document list update request is issued when an operation related to updating the document list is executed by a user login timing or a user operation on the already displayed document list screen 1000 (FIG. 10).

  If it is determined that a document list update request has not been issued (NO in S1301), the process waits until a document list update request is issued. On the other hand, as a result of the determination, if a document list update request is issued (YES in S1301), in S1302, the print management function 1331 of the print application 1310 determines that the issued document list update request is the document list screen 1000 or the document list. It is determined whether the request is made when the “update from name service” button on the screen 1100 is pressed.

  As a result of the determination, if it is a request when the “update from name service” button is pressed (YES in S1303), the process proceeds to S1304. On the other hand, as a result of the determination, if the request is not a request when the “update from name service” button is pressed (NO in S1303), that is, if it is determined as a normal update request, the print management of the print application 1310 is performed in S1303. The function 1331 determines whether or not the forced local print mode of the setting information is set to “ON”.

  As a result of the determination, if the forced local print mode is set to “ON” (YES in S1303), the process advances to S1323 without acquiring the bibliographic information of the print data accumulated in the MFP 300 on the network. On the other hand, as a result of the determination, if the forced local printing mode is not set to “ON” (NO in S1303), that is, if the forced local printing mode is set to “OFF”, the MFP 300 on the network 400 is set. In order to obtain the bibliographic information of the print data stored in, the processing from S1304 is performed.

  Whether or not the forced local print mode is selected is determined based on the setting information of the print application 1310 shown in FIG. Specifically, first, it is determined whether or not the value held in the forced local print mode 602 in the setting information is ON. When the value held in the forced local print mode 602 in the setting information is “ON”, the forced local print mode time 603 is acquired, and it is determined whether or not the current time is within the range of the forced local print mode time 603. To do. If the current time is within the forced local print mode time 603, the process advances to step S1323. On the other hand, when the value held in the forced local print mode 602 in the setting information is “OFF”, the name information is acquired, but the power-saving multifunction device 300 is controlled so as not to return as much as possible.

  Even in an environment where a plurality of multifunction peripherals are installed at a base or a floor, a user often accumulates print data in a multifunction peripheral closest to his / her seat and prints from the multifunction peripheral. A use case in which printing is performed by a multifunction device different from the multifunction device that stores the print data is considered to be a case where the multifunction device that stores the print data is operated by another user. The operation peak time of the MFP is fixed to some extent. For example, in the morning or before the meeting. Based on this, it is rare for multiple users to operate the same multifunction device at the same timing except during the operation peak time of the multifunction device, and the frequency of printing with a multifunction device different from the multifunction device that stores print data is It is thought that there are few. Except for the operation peak time period (specifically, after a fixed time, etc.), it is possible to eliminate the communication that occurs when the document list is updated, and to suppress the case of returning from the power saving mode unnecessarily.

  When the forced local print mode is “OFF”, it is possible to set the time for which the forced local print mode is continued. The forced local print mode is “OFF” and the current time is set. If it is within the time, the name information is acquired, and the MFP in the power saving state is configured to prohibit the inquiry of the bibliographic information. That is, when the forced local print mode is “OFF” and after a fixed time (the set time is, for example, 17:30 to 09:00), the inquiry is prohibited as shown in FIG. The identification information of the multifunction peripheral is displayed on the document list screen 1000. In addition, if the forced local printing mode is “OFF” and it is within a fixed time, the MFP is operated so as to make an inquiry to the power saving state MFP. By performing this operation, it is possible to obtain a list of all print data stored in the multifunction device with priority on work efficiency during the scheduled time, and prioritize power saving during the scheduled time. Inquiries can be prohibited for multifunction devices at first.

  Returning to the description of FIG.

  In step S <b> 1304, the print management function 1331 of the print application 1310 acquires user information (logged-in user information) of a user who is currently logged in to the multifunction peripheral 300. In step S <b> 1305, the print management function 1331 of the print application 1310 acquires a user name in the acquired user information, and transmits a name information acquisition request including the user name to the multi-function peripheral 300 (NAME_SERVICE).

  In step S1306, the name information management function 1351 of the print application 1310 in the multifunction device 300 (NAME_SERVICE) receives the name information acquisition request transmitted from the multifunction device 300 (PRINT). In step S1307, the name information management function 1351 of the print application 1310 acquires the user name in the received name information acquisition request, and searches whether the name information file of the target user is stored in the own apparatus. In step S1308, the name information management function 1351 of the print application 1310 transmits name information as a search result to the multi-function peripheral 300 (PRINT) as a response to the name information acquisition request. Here, if there is no name information of the target user, name information including information indicating “empty” is transmitted as a response to the name information acquisition request.

  In step S1309, the print management function 1331 of the print application 1310 in the MFP 300 (PRINT) receives name information transmitted from the MFP 300 (NAME_SERVICE). In step S1310, the print management function 1331 of the print application 1310 transmits a host status acquisition request to the MFP 300 (NAME_SERVICE).

  In step S1311, the host status management function 1341 of the print application 1310 in the multifunction device 300 (NAME_SERVICE) receives a host status acquisition request from the multifunction device 300 (PRINT). In step S1312, the host status management function 1341 of the print application 1310 acquires the host status information illustrated in FIG. 9 and transmits the host status information to the multifunction peripheral 300 (PRINT) as a response to the host status acquisition request.

  In step S1313, the print management function 1331 of the print application 1310 in the multifunction peripheral 300 (PRINT) receives host status information transmitted from the multifunction peripheral 300 (NAME_SERVICE). In FIG. 13, the host status information is transmitted in S1313. However, the host information may be included in the name information transmitted in S1308.

  In step S1314, the print management function 1331 of the print application 1310 determines whether name information of the target user exists from the received name information. As a result of the determination, if the name information does not exist (NO in S1314), the print data of the target user does not exist in the MFP 300 on the network 400, so the process proceeds to S1323. On the other hand, if the name information is present as a result of the determination (YES in S1314), the processing from S1315 onward is performed in order to obtain the bibliographic information of the print data from the MFP 300 on the network 400.

  In step S1315, the print management function 1331 of the print application 1310 repeats the processing in steps S1316 to 1322 for the number of multifunction peripherals (the number of hosts) included in the received name information.

  In step S1316, the print management function 1331 of the print application 1310 acquires host information included in the name information, and determines whether the status of the target host (multifunction device) is ACTIVE from the host status information of all received hosts. judge.

  As a result of the determination, if the status of the target host is ACTIVE (YES in S1316), in S1318, the print management function 1331 of the print application 1310 obtains a list of bibliographic information of the target host (active state MFP). The bibliographic information list acquisition request is sent to the target host (multifunction machine 300 (STORAGE)).

  Here, the MFP 300 (PRINT) acquires name information and host status information, determines the MFP in the power saving state, and requests the bibliographic information list acquisition request to the MFP 300 (STORAGE) not in the power saving state. However, the present invention is not limited to this. For example, the MFP 300 (NAME_SERVICE) may be configured to determine a MFP that is not in the power saving state, and transmit a bibliographic information list acquisition request to the MFP 300 (STORAGE) that is not in the power saving state.

  Specifically, when name information is transmitted to the MFP 300 (PRINT), the name information of the MFP that is in the ACTIVE state (not in the power saving state) is identified from the name information searched in S1307 and responds. In this case, when it is determined that a bibliographic information inquiry is made to another multifunction device by a user operation on the multifunction device 300 (PRINT), the multifunction device is in a power saving state in accordance with a request from the multifunction device 300 (PRINT). Send name information to

  On the other hand, as a result of the determination, if the status of the target host is not ACTIVE (NO in S1316), that is, if the status is SLPEEP, the process proceeds to S1317 so as not to return the multifunction peripheral.

  In step S1317, the print management function 1331 of the print application 1310 prohibits (suppresses) the acquisition of bibliographic information from the target host, and adds the host information of the target host to the SLEEP list. Specifically, the host information included in the name information and the last storage date / time of the host information are linked and stored in the SLEEP list. Here, the SLEEP list is a list for managing host information about a multifunction peripheral that is prohibited from acquiring bibliographic information because it is in the SLEEP state, and is held as a file on the RAM 302, for example. Accordingly, since it is possible to make an inquiry to the multifunction peripheral while maintaining the power saving state, printing from the multifunction peripheral in the power saving state can also be executed, and the printing job can be continued.

  As a result, it is not necessary to inhibit (suppress) inquiries to the multifunction machine in the power saving state, and it is unnecessary to operate the multifunction machine unnecessarily, so that the power saving effect can be maintained. In particular, since the multifunction device is in a power saving state after a fixed time, a higher effect can be obtained.

  In step S <b> 1319, the bibliographic information management function 1321 of the print application 1310 in the multifunction peripheral 300 (STORAGE) receives the bibliographic information list acquisition request transmitted from the multifunction peripheral 300 (PRINT). In step S1320, the bibliographic information management function 1321 of the print application 1310 acquires user information included in the received bibliographic information list acquisition request, and determines whether there is a bibliographic information list (print data list) for the target user indicated by the user information. Search for. In step S1321, the bibliographic information management function 1321 of the print application 1310 transmits the bibliographic information list that is the search result to the multifunction peripheral 300 (PRINT) as a response to the bibliographic information list acquisition request.

  In step S1322, the print management function 1331 of the print application 1310 in the MFP 300 (PRINT) receives the bibliographic information list transmitted from the MFP 300 (STORAGE). In step S <b> 1323, the print management function 1331 of the print application 1310 acquires a list of bibliographic information of the target user in the own apparatus managed by the bibliographic information management function 1321. In step S <b> 1324, the print management function 1331 of the print application 1310 sorts the target hosts added to the SLEEP list in order of last saved date and time.

  In step S1325, the print management function 1331 of the print application 1310 displays a document list screen (FIG. 10A). Specifically, on the document list screen, first, the bibliographic information of the document (print data) stored in the active MFP on the network acquired in S1315 to S1322 and stored in the own apparatus acquired in S1323. The bibliographic information of the documents (print data) being sorted is sorted and displayed in order of oldest storage date. Below that, only the host name and the last saved date and time are displayed as the host information in the SLEEP state sorted in S1324. This is because the user is highly likely to print a recently saved document, so the host information in the SLEEP state is displayed in order from the latest saved date.

  When a host in SLEEP state is selected on the document list screen, processing for returning the host is executed. This process will be described with reference to FIG. In particular, FIG. 14 shows processing for acquiring bibliographic information from the target multi-function peripheral and updating the document list when the SLEEP host in the document list screen 1000 (FIG. 10A) is selected. Note that the processing in FIG. 14 is realized by cooperation of the multifunction device 300 (PRINT) and the multifunction device 300 (STORE). The processing executed by the multifunction machine 300 is realized, for example, by the CPU 301 reading a program stored in the ROM 303 and executing it on the RAM 302.

  In step S1401, the print management function 1331 of the print application 1310 in the multifunction peripheral 300 (PRINT) selects a host in the SLEEP state on the document list screen, and the selected target host (multifunction peripheral 300 (STORE)) is selected. Send a bibliographic information list acquisition request.

  In step S1402, the bibliographic information management function 1321 of the print application 1310 in the multifunction peripheral 300 (STORAGE) receives the bibliographic information list acquisition request transmitted from the multifunction peripheral 300 (PRINT). The multifunction device 300 (STORE) returns to the ACTIVE state when communication from another device on the network occurs while the MFP 300 is in the SLEEP state. When a status change occurs, a host status change notification is transmitted to the multi-function peripheral operating in the [NAME_SERVICE] mode. This process will be described later.

  In step S1403, the bibliographic information management function 1321 of the print application 1310 acquires user information included in the received bibliographic information list acquisition request, and determines whether there is a bibliographic information list (print data list) for the target user indicated by the user information. Search for. In step S <b> 1404, the bibliographic information management function 1321 of the print application 1310 sends the bibliographic information list that is the search result to the MFP 300 (PRINT) as a response to the bibliographic information list acquisition request. Send.

  In step S1405, the print management function 1331 of the print application 1310 in the multifunction peripheral 300 (PRINT) receives the bibliographic information list transmitted from the multifunction peripheral 300 (STORE). In step S1406, when the print management function 1331 of the print application 1310 receives the bibliographic information list, the print management function 1331 updates the document list stored in the active MFP in the document list screen displayed in step S1325 of FIG. Further, the print management function 1331 of the print application 1310 deletes the host information (multifunction peripheral information) of the target host from the SLEEP list held in S1317, and the corresponding host information displayed on the document list screen shown in FIG. Is deleted. Furthermore, as shown in FIG. 11, the print management function 1331 of the print application 1310 displays a document list corresponding to the bibliographic information list acquired in S1406 so that it is preferentially selected. Thereby, it is possible to improve the convenience of the printing operation.

  FIG. 15 shows processing when the host status of the MFP 300 is changed. Note that the processing in FIG. 13 is realized by cooperation of the multifunction device 300 and the multifunction device 300 (NAME_SERVICE). The processing executed by the multifunction machine 300 is realized, for example, by the CPU 301 reading a program stored in the ROM 303 and executing it on the RAM 302.

  The MFP 300 has an active mode in the normal operation state and a SLEEP mode in the power saving state. When the MFP 300 is activated, it is activated in the ACTIVE mode. If the operation unit 308 of the multifunction device 300 is not operated for a certain period of time or if no data transmission / reception occurs via the network, the multifunction device 300 shifts to the SLEEP mode. When the operation unit 308 of the MFP 300 is operated in the SLEEP mode, or when data transmission / reception occurs via the network, the MFP 300 returns from the SLEEP mode to the ACTIVE mode.

  The present embodiment aims to prevent unnecessary communication from being generated in the MFP 300 in the SLEEP mode. Therefore, the MFP 300 (NAME_SERVICE) has the status of other MFPs 300 connected via the network 400 ( Understand (ACTIVE / SLEEP). Therefore, when the status of the MFP 300 is changed, the MFP 300 whose status has been changed generates a process of notifying the MFP 300 (NAME_SERVICE) of the status change.

  Hereinafter, this process will be specifically described with reference to FIG.

  In step S1501, the host status management function 1341 of the print application 1310 determines whether the status of the MFP 300 has been changed. Actually, the status transition of ACITVE → SLEEP or SLEEP → ACTIVE is monitored, and when the status transition occurs, it is determined that the status has been changed. This status acquires the status via the multifunction device platform. If there is a change in state, it can be determined by receiving a notification from the platform.

  If the status is not changed as a result of the determination (NO in S1501), the process waits until it is changed. On the other hand, if the status is changed as a result of the determination (YES in S1501), in S1502, the host status management function 1341 of the print application 1310 transmits a host status change notification to the multifunction device 300 ([NAME_SERVICE). This host status change notification includes the host name and the state after migration (ACTIVE or SLEEP).

  In step S1503, the host status management function 1341 of the print application 1310 of the MFP 300 (NAME_SERVICE) receives the host status change notification transmitted from the MFP 300 in which the status change has occurred. In step S <b> 1504, the host status management function 1341 of the print application 1310 determines whether there is a transmission source host that has transmitted the host status change notification in the host status information (FIG. 9) held in the own apparatus.

  As a result of the determination, when the transmission source host exists in the host status information (YES in S1504), in S1506, the host status management function 1341 of the print application 1310 displays the status in the target host information of the host status information as the host status. Rewrite and update the status included in the change notification.

  On the other hand, as a result of the determination, if there is no transmission source host in the host status information (NO in S1504), in S1505, the host status management function 1341 of the print application 1310 newly adds the host information to the host status information. In step S1506, the host status management function 1341 of the print application 1310 rewrites the status in the target host information of the host status information with the status included in the host status change notification and updates it.

  FIG. 16 shows processing when the user selects a document on the document list screen 1000 (FIG. 10A) and is instructed to print. Note that the processing in FIG. 16 is realized by cooperation of the multifunction device 300 (PRINT) and the multifunction device 300 (STORE). The processing executed by the multifunction machine 300 is realized, for example, by the CPU 301 reading a program stored in the ROM 303 and executing it on the RAM 302.

  In step S1601, the print management function 1331 of the print application 1310 in the MFP 300 (PRINT) acquires the documents selected on the document list screen 1000, and repeats the processing in steps S1602 to S1605 for the number of selected documents. .

  In step S1602, the print management function 1331 of the print application 1310 acquires the bibliographic information of the selected target document. In step S1603, the print management function 1331 of the print application 1310 determines, based on the host information included in the acquired bibliographic information, the MFP 300 (STORE) that stores print data corresponding to the selected target document. Send a print request for the target document.

  In step S <b> 1604, the print management function 1331 of the print application 1310 in the MFP 300 (STORAGE) receives the print request transmitted from the MFP 300 (PRINT). In step S1605, based on the received print request, the print management function 1331 of the print application 1310 transmits the print data of the target document to the MFP 300 (PRINT) that is the transmission source of the print request, and executes printing. .

  As described above, according to the present embodiment, the print data is accumulated in the multifunction peripheral that is the image forming apparatus, and the print data accumulated from the desired image forming apparatus is acquired and output. The return from the power saving state of the forming apparatus can be reduced. In addition, since only necessary multifunction peripherals can be restored, print data can be output while maintaining power saving. In this way, the power consumption of the entire system can be reduced and efficient operation can be performed.

  Note that the present invention supplies a program that realizes one or more functions of the above-described embodiments to a system or apparatus via a network or a storage medium, and one or more processors in a computer of the system or apparatus execute the program. It can also be realized by a process of reading and executing. It can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
