The data storage 120 includes a fixed storage 122 such as an HDD (Hard Disc Drive) and a removable storage 124 such as a memory card. The fixed storage 122 stores data in a predetermined format in which processed document / image data can be reused. The removable storage 124 that stores information such as control programs and the like and stores various pieces of device management information and data that needs to be added or changed, such as control programs, is used for control. These data stored in the data storage 120 are subject to acquisition requests from other MFPs by the remote access function described in detail later. Further, the data storage 120 is used as a place for storing a copy (copy) of data acquired from another MFP by the remote access function.
The MFP 100 includes a control board 110 that functions as a main controller that controls the entire apparatus, and a control board 130 that controls the scanner 132 and the plotter 134 under the control of the main controller. The remote access function described in detail later (see FIG. 4) is mounted on the control board 110, and accesses information such as document / image data and device management information held by other MFPs and PCs. The requested information is obtained in response to an access from another MFP.

FIG. 2 shows a software configuration in the control board 110 that functions as a main controller. FIG. 2 shows a configuration of a main part related to the remote access function of this embodiment.
The software in the control board 110 that functions as a main controller is constructed by adding elements that realize functions newly required in the present embodiment on the premise of a configuration adopted in an existing MFP.
The prerequisite software configuration of the MFP includes a software group including three layers of an OS (Operating System) layer 230, a middleware layer 220, and an application layer 210.
Applications such as the copy application 211, the printer application 212, the fax application 213, and the scanner application 214 in the application layer 210 are used when the application functions of the MFP are used. The screen display control program that performs application-specific processing such as screen control, key operation control, and job generation is the main component.
In addition, the OS layer 230 and the middleware layer 220 interpret a processing request from an application, generate a hardware resource acquisition request, and perform processing necessary for each application in order to manage the hardware resource. Treat centrally. For this purpose, the middleware layer 220 includes a control service (not shown), a system resource manager (not shown), and an OS layer 230. Details of the software configuration of the MFP assumed here are, for example, Japanese Patent Application Laid-Open No. 2004-7346 (see FIG. 1 of the same publication) and Japanese Patent Application Laid-Open No. 2004-7346 (see FIG. 1 of the same publication). Therefore, we will refer to these descriptions.
A remote file access application 215 is installed in the application layer 210 as software for realizing the remote access function. In response to access from another MFP, this application performs processing for transmitting information such as a requested file to the request source. The network redirector 227 implemented in the middleware layer 220 accesses information such as files of other MFPs and PCs, and implements a network client function with this software.

FIG. 3 shows the transition of operation events when an access request from the MFP as a client to the MFP as a server is requested. In FIG. 3, the sequence of access operations is executed in the order of (1) → (12) in the figure.
FIG. 4 shows a flow of information between MFPs when the operation sequence shown in FIG. 3 is executed as a processing flow when accessing the HDD 122 of the MFP 100 s serving as the server from the MFP 100 c serving as the client through the network 190. is there. 4 are numbered (1) to (12) indicating the sequence order in association with the operation sequence in FIG.
In the following, the access operation to the stored document file of server MFP 100s will be described with reference to the transition of the operation event shown in FIG.
Sequence (1): First, when the client MFP 100c makes a browse request to the server MFP 100s that can access a file via the network I / F 170 and the network redirector 227 (event Ev101), the remote file access of the server MFP 100s is performed. The application 215 receives this browse request, attaches a computer name (: Mymfp01), and returns a browse response (event Ev102).
Sequence (2): Next, client MFP 100c specifies a computer name (: Mymfp01) and requests a resource name to be accessed from server MFP 100s (event Ev103). In response to this browse request, server MFP 100s attaches a resource name (: share) to be connected as an access target, and returns a resource name response (event Ev104).
Sequence (3): Next, when the client MFP 100c makes a protocol negotiation request to the server MFP 100s that requests connection as an access target (event Ev105), the server MFP 100s confirms that this request is satisfied and responds to the request. As a result, a session setup screen necessary for connection is returned (event Ev106).

Sequence (4): Next, the client MFP 100c inputs a user ID / password or the like necessary for user authentication, attaches these data, and performs a session setup procedure (event Ev107). Upon receiving this procedure, server MFP 100s performs user authentication (events Ev108 and 109), and returns a session setup response to client MFP 100c on the condition that the authentication has been obtained (event Ev110). At this time, since user authentication is performed as part of the remote access function, an authentication request with the user ID / password received by the remote file access application 215 is sent to the authentication module 223 (event Ev108), and the authentication result Is obtained as an authentication response therefrom (event Ev109).
If user authentication fails, the client MFP 100c notifies the user of the authentication result as an error message display. Further, it may be possible to prevent an accidental error by adopting a method of responding by displaying a screen prompting re-input of a user ID / password when user authentication fails.
Sequence (5): Next, in response to the session setup, the client MFP 100c identifies the resource (\\ Mymfp01 \ share) obtained in sequence (2) and makes a connection request to the resource (event Ev111) In response to this connection request, server MFP 100s returns a resource connection response (event Ev112).
Sequence (6): Next, in response to the resource connection response, the client MFP 100c has registered the user name (referred to as “user01”) in the previous sequence (4). In response to this inquiry (event Ev113), the server MFP 100s returns a folder information response as folder: user01 if the folder exists (event Ev114). ).

At this time, along with the response of the folder information from server MFP 100s, an operation screen of remote file access application 215 for using the remote access function is transmitted and opened on client MFP 100c.
FIG. 5 shows an example of an operation screen for remote file access displayed on the liquid crystal touch panel 152 of the operation panel 150. The screen of the liquid crystal touch panel 152 shown in FIG. 5 uses the folder / file information 152a, 152f, 152c, 152i, and 152v (detailed later) of the file that the client MFP 100c requests to access and the file read by remote access. Then, a setting key 152k for a processing mode such as image output performed by the client MFP 100c is displayed. Note that the operation panel 150 shown in FIG. 5 includes a remote file access button 151 that is operated when the remote access function is activated, as one of function buttons for selecting various composite functions such as copy / fax of the MFP.
In the operation of sequence (6), since the existence of the folder: user01 is confirmed, this result is reflected in the folder configuration 152f on the screen of FIG. The folder structure 152f in the figure displays the icons of the folders in a hierarchical arrangement.
Sequence (7): In order to specify the file to be accessed, file information for knowing the contents of the folder: user01 is further required. As a procedure, the client MFP 100c uses the folder (\ \ Mymfp01 \ share \ user01) and making a file information acquisition request indicating the folder configuration (event Ev115), the server MFP 100s receives the request and receives a plurality of folders for the installed applications. Is present (here, folders: copier, fax, printer, scanner), a folder information response indicating the folder structure is returned (event Ev116).

Sequence (8): Next, the client MFP 100c specifies the folder (\\ Mymfp01 \ share \ user01 \ copier) of the file to be accessed, and requests acquisition of the file information of the file contained in this folder Upon receiving this request (event Ev117), the server MFP 100s returns a response of file information indicating the file name and the like contained in the folder: copier (event Ev121).
However, since the bibliographic information such as the file name is stored in the HDD 122 used for storing the document / image data of each file, it is necessary to access the HDD 122 via the copy application 211. That is, the remote file access application 215 that receives the file information acquisition request from the client MFP 100c makes this acquisition request to the copy application 211 (event Ev118). Upon receiving this acquisition request, the copy application 211 reads the file information by reading the HDD 122 (event Ev1119), and passes the acquired file information to the remote file access application 215 as a response to the request (event Ev120). ).
At this time, the currently accessed folder (hereinafter referred to as “current folder”) is displayed as “\\ Mymfp01 \ share \ user01 \ copier” in the address field 152a in FIG. 5, and the file display field 152d in FIG. In the folder: copier, if there are three image data, each file name is report 01.tiff, report 02.pdf, business trip expense-01.tiff, The display is performed by an icon 152c with a file name.

In addition, the remote file access operation screen displayed on the liquid crystal touch panel 152 as shown in FIG. 5 can be displayed in accordance with the GUI function, and can be used to display icons for image data read by remote access. It is possible to change the screen display as shown in (1) to (4) below by input operation.
(1) The current folder is changed to the folder of the target icon by performing a double click operation on the target icon on the display screen in which the folder structure is represented by an array of icons of each folder.
(2) A document / image data preview of the target icon is displayed by performing a click operation on the target icon on the display screen representing each file of the document / image data as an icon. The preview display is performed in the preview display field 152v on the display screen of FIG.
(3) A double-click operation is performed on the target icon on the display screen representing each file of document / image data as an icon, thereby displaying an enlarged preview of the document / image data of the target icon.
(4) The attribute information of the document / image data of the target icon is displayed by performing a double-click operation on the target icon on the display screen representing each file of the document / image data as an icon. The attribute information is displayed in the document information display field 152i on the display screen of FIG. 5, and the display content includes, for example, so-called bibliographic information, setting information by user operation, and the like.
If new file information needs to be acquired as a result of the above input operation to the icon of the remote file access input screen, the operation of sequence (8) is repeated and the obtained file information is displayed on the screen. To reflect.

Sequence (9): Next, the client MFP 100c specifies a file (\\ Mymfp01 \ share \ user01 \ copier \ report 01.tiff), and as an access procedure, first requests opening of this file ( Event Ev122). Since this document file is stored in the HDD 122, the remote file access application 215 that receives the file open request from the client MFP 100c asks the HDD 122 via the copy application 211 whether the file can be opened (events Ev123, 124). ), And the result is obtained by a response (event Ev125). If the file can be opened, remote file access application 215 that has received this response returns this response to client MFP 100c (event Ev126).
Sequence (10): Having received a response that the file can be opened, the client MFP 100c next requests Read access of the file that requested the file open (event Ev127). At the time of Read access, since it is performed in the same route as the file open request, the remote file access application 215 that receives the file read request from the client MFP 100c makes a Read request to the HDD 122 via the copy application 211 (event Ev127, 128) When the file read is started in the HDD 122 in response to this request, a file read response is returned to the client MFP 100c (event Ev129, 130). The copy application 211 performs a file read on the HDD 122 (event Ev131), and sends the read file data to the client MFP 100c via the remote file access application 215 (events Ev132 and 133).

Thereafter, client MFP 100c that receives the read file data processes the file data in accordance with a user instruction. For example, the processing mode such as “document copy”, “print”, “FAX transmission”, and “E-mail transmission” shown in the setting key 152k on the operation screen of FIG. 5 is performed as processing performed using this file data. When a file in the file display field 152d is designated and the setting key 152k is operated, the selected processing mode is activated according to this input operation.
When “document copy” is selected, the data received from server MFP 100 s is transferred to the HDD of storage 120 in the client and stored therein. That is, data is copied (copied) between HDDs 122 of server MFP 100s and client MFP 100c.
When any of “print”, “FAX transmission”, and “E-mail transmission” is selected, an application necessary for each image output process is started, and the process is executed using the file data acquired from server MFP 100s. The operation at the time of “print” output will be described in detail in an example described later.
As described above, client MFP 100c finishes the transfer process of data passed from server MFP 100s in accordance with the set processing mode, confirms that the file read is completed, and confirms the completion via remote file access application 215. The copy application 211 is notified (events Ev 134 and 135).

Sequence (11): In this operation sequence of the remote access function, it is possible to write back data to server MFP 100s after applying some processing to the file data obtained from server MFP 100s by Read access (sequence (10)). Therefore, this sequence is provided for this purpose. Client MFP 100c instructed by the user to write back the file data requests write of the file (event Ev141). The remote file access application 215 that receives a file write request from the client MFP 100c makes a write request to the copy application 211 (event Ev142). A response from the copy application 211 that confirms that it is ready to receive this request is returned to the client MFP 100c via the remote file access application 215 (events Ev143 and 144). The client MFP 100c that receives the file write OK sends the file data to be written back to the copy application 211 via the remote file access application 215 (events Ev145 and 146). The copy application 211 that receives the file data instructs the HDD 122 to write the file, sends the received file data (event Ev147), and after sending it, confirms that the file write has been completed, The client MFP 100c is notified via the access application 215 (event Ev148, 149).
Sequence (12): Next, the client MFP 100c performs processing for closing the file (\\ Mymfp01 \ share \ user01 \ copier \ report 01.tiff) opened in sequence (9). As a closing procedure, first, this file is specified and a closing is requested (event Ev151). The remote file access application 215 that receives the file close request from the client MFP 100c asks the HDD 122 whether or not the file can be closed via the copy application 211 (event Ev152, 153), and obtains the result as a response (event Ev154). The remote file access application 215 that has obtained the response result that it can be closed returns this response to the client MFP 100c (event Ev155). If the sequence (11) is unnecessary, the file close process of the sequence (12) is performed following the Read access (sequence (10)).

Next, another remote access function installed in the above-described image processing apparatus (FIGS. 1 and 2) will be described based on an embodiment.
In the embodiment of the remote access function described with reference to FIGS. 3 and 4, an example related to the function of accessing a document file stored in another MFP via the network is shown. However, in this embodiment, the function via the network is used. An embodiment relating to a function of accessing device management information (user information, device setting information, etc.) held in another MFP or server machine will be described.
6 and 7 show the operation of the embodiment relating to this access function.
FIG. 6 shows the transition of operation events when an access request from the MFP as a client to the MFP as a server is requested. In FIG. 6, the sequence of access operations is executed in the order of (1) → (11) in the figure.
FIG. 7 shows a flow of information between MFPs when the operation sequence shown in FIG. 6 is executed as a processing flow when accessing the nonvolatile memory 123 of the MFP 100s serving as the server from the MFP 100c serving as the client through the network 190. Is. Note that the arrows (1) to (11) indicating the sequence order are attached to the arrows indicating the flow of information in FIG. 7 in association with the operation sequence in FIG.
Hereinafter, with reference to the transition of the operation event shown in FIG. 6, an access operation to the device management information file such as user information and device setting data held in the nonvolatile memory 123 of server MFP 100s will be described.
Sequence (1): First, when the client MFP 100c makes a browse request to the server MFP 100s that can access the file via the network I / F 170 and the network redirector 227 (event Ev201), the remote file access of the server MFP 100s is performed. The application 215 receives this browse request, attaches a computer name (: Mymfp01), and returns a browse response (event Ev202).
Sequence (2): Next, client MFP 100c specifies a computer name (: Mymfp01) and requests a resource name to be accessed from server MFP 100s (event Ev203). Upon receiving this browse request, server MFP 100s attaches a resource name (: share) to be connected as an access target and returns a resource name response (event Ev204).
Sequence (3): Next, when the client MFP 100c makes a protocol negotiation request to the server MFP 100s that requests connection as an access target (event Ev205), the server MFP 100s confirms that this request is satisfied and responds to the request. The session setup screen necessary for connection is returned (event Ev206).

Sequence (4): Next, the client MFP 100c inputs a user ID / password or the like necessary for user authentication, attaches these data, and performs a session setup procedure (event Ev207). In response to this procedure, server MFP 100s performs user authentication (event Ev208, 209), and returns a session setup response to client MFP 100c on the condition that the authentication is obtained (event Ev210). At this time, since user authentication is performed as part of the remote access function, an authentication request with the user ID / password received by the remote file access application 215 is sent to the authentication module 223 (event Ev208), and the authentication result Is obtained as an authentication response therefrom (event Ev209).
If user authentication fails, the client MFP 100c notifies the user of the authentication result as an error message display. Further, it may be possible to prevent an accidental error by adopting a method of responding by displaying a screen prompting re-input of a user ID / password when user authentication fails.
Sequence (5): Next, in response to the session setup, the client MFP 100c identifies the resource (\\ Mymfp01 \ share) obtained in sequence (2) and makes a connection request to the resource (event Ev211) The server MFP 100s receives this connection request and returns a resource connection response (event Ev212).
Sequence (6): Next, in response to the resource connection response, the client MFP 100c has registered the user name (here, the administrator user name is “admin”) in the previous sequence (4). When asking whether or not the folder “admin” exists in the resource (\\ Mymfp01 \ share) (event Ev213), the server MFP 100s receives this inquiry, and if the folder exists, the folder: admin As a response to the folder information (event Ev214).

Sequence (7): In order to specify the file to be accessed, file information for knowing the contents of the folder: admin is further required. As a procedure, the client MFP 100c uses the folder (\ (\ Mymfp01 \ share \ admin) is specified, and a request for acquiring file information of the files contained in this folder is made (event Ev215). In response to this request, if there are a plurality of files in the folder, server MFP 100s names these files (here, Charge Counter.txt, User Programs.txt, User Counter.csv, Address.csv) A response of file information indicating the above is returned (event Ev218). Here, since the file name and the like are obtained from the device information management module 225 that manages device management information such as user information and device setting data, a remote file that receives a file information acquisition request in the folder: admin from the client MFP 100c. The access application 215 makes this acquisition request to the device information management module 225 (event Ev216), and obtains file information of the corresponding folder as a response to the request (event Ev217).
Sequence (8): Next, the client MFP 100c specifies a file (\\ Mymfp01 \ share \ admin \ Charge Counter.txt) to be accessed from the folder, and as an access procedure, first of all, Opening is requested (event Ev219). Since this device management information file is stored in the nonvolatile memory 123 and is managed by the device information management module 225, the remote file access application 215 that receives a file open request from the client MFP 100c is the device information management module. Ask 225 whether or not to open (event Ev220), and obtain the result as a response (event Ev221). If the file can be opened, the remote file access application 215 that has received this response returns this response to the client MFP 100c (event Ev222).

Sequence (9): Having received a response that the file can be opened, the client MFP 100c next requests Read access of the file that requested the file open (event Ev223). At the time of Read access, the remote file access application 215 that receives a file read request from the client MFP 100 c makes a read request to the device information management module 225 for the nonvolatile memory 123 (event Ev 224), and receives this request in the nonvolatile memory 123. When the file read is started, a file read response is returned to the client MFP 100c (event Ev226, 227). The device information management module 225 reads the file in the nonvolatile memory 123 (event Ev225) and sends the read file data to the client MFP 100c via the remote file access application 215 (event Ev228, 229). Thereafter, client MFP 100c that receives the read file data transfers the data to nonvolatile memory 123 that stores device management information in the client. That is, data is copied (copied) between the nonvolatile memory 123 of the server MFP 100s and the client MFP 100c.
The client MFP 100c finishes the transfer process, confirms that the file read is completed, and notifies the device information management module 225 of the completion via the remote file access application 215 (events Ev230 and 231).

Sequence (10): This operation sequence of the remote access function has a mechanism for writing back data to server MFP 100s after applying some processing to the file data obtained from server MFP 100s by Read access (sequence (9)). For this purpose, a sequence (10) is provided. Client MFP 100c instructed to write back file data by the user requests write of the file (event Ev235). The remote file access application 215 that receives a file write request from the client MFP 100c makes a write request to the device information management module 225 (event Ev236). A response from the device information management module 225 for confirming that the condition for accepting this request is satisfied is returned to the client MFP 100c via the remote file access application 215 (events Ev237, 238). In this example, since the response of the file Write is Ru NG der, notifies the client MFP100c. Depending on the file, it is possible to accept a write request for changing the setting by giving the administrator authority. In this case, client MFP 100 c sends file data to be written back to device information management module 225 via remote file access application 215. The device information management module 225 that receives the file data to be written back instructs the nonvolatile memory 123 to write the file, sends the received file data, and after sending it, confirms that the file write has been completed. The client MFP 100c is notified via the file access application 215.
Sequence (11): Next, the client MFP 100c performs processing to close the file (\\ Mymfp01 \ share \ admin \ ChargeCounter.txt) opened in sequence (8). As a closing procedure, first, this file is specified and a closing is requested (event Ev241). The remote file access application 215 that receives a file close request from the client MFP 100c asks the device information management module 225 whether or not the file can be closed (event Ev242), and obtains the result by a Close response (event Ev243). The remote file access application 215 that has obtained the response result that it can be closed returns this response to the client MFP 100c (event Ev244). If the sequence (10) is unnecessary, the file close process of the sequence (11) is performed following the Read access (sequence (9)).

The following embodiment relates to a printing process performed using document file data acquired by the remote access function (see FIGS. 3 and 4).
As described above, the remote access function of the present plan enables image output processing using the acquired document file data by a series of processing flows subsequent to data acquisition. In the example of the remote file access operation screen shown in FIG. 5, the image output processing by the remote access function is performed by operating the setting mode 152k for the processing modes of “print”, “FAX transmission”, and “E-mail transmission”. Is selected. When the “print” key is selected, the printing process of this embodiment is executed.
This print processing can be performed by linking a print processing application mounted on the control board 110 on the client MFP 100c side with the remote file access application 215 on the server MFP 100s side.
Here, three forms of image output processing by the remote access function are shown as “remote document printing processing (I) to (III)”.
"Remote Document Printing Process (I)"
In the remote document printing process of this embodiment, all data of a document file to be remotely accessed is copied to the client MFP 100c, and then the printing process is performed based on the copied data.
FIG. 8 shows a flowchart of the remote document printing process of this embodiment.
According to the processing flow of FIG. 8, when a user requests a document printing process using the remote access function in the client MFP 100c, the server MFP 100s responds to the request and the document instructed as an access target from the document file stored in the HDD 122. Send the file. At this time, the file data to be transmitted is sent in such a manner that all the data is collectively transferred to a storage location such as the HDD 122 used for storing print processing data in the client MFP 100c, whereby the server-side document is stored in units of files. Copy to the client side (step S101).
Next, the client MFP 100c performs print processing using the data of one document file copied to the storage location such as the HDD 122 (step S102).
After the print processing, the document file data copied to the client MFP 100c side is deleted in order to centrally manage the document on the server MFP 100s side and save the storage capacity (step S103), and this processing flow is ended. .
The application that performs the printing process using the data of one document file copied to the HDD 122 by the above printing process is the same as the printing process by the document box function. Therefore, the application is executed by using the application of the document box function. Is possible.

"Remote Document Printing Process (II)"
In the remote document print processing method of this embodiment, the document file data targeted for remote access is copied to the client MFP 100c for each page, and the print processing is performed based on the copied data for each page. To do. In the remote document printing process (I) described above, since all data of one document file is copied, the capacity may become insufficient depending on the state of available resources. The present embodiment employs a page-by-page processing method that requires a small storage capacity in order to enable print processing even in such a resource state.
FIG. 9 shows a flowchart of the remote document printing process of this embodiment.
According to the processing flow of FIG. 9, when a user requests a document printing process using the remote access function in the client MFP 100c, the server MFP 100s responds to the request and the document instructed as an access target from the document file stored in the HDD 122. Send the file. At this time, the file data to be transmitted is sent in such a manner that it is transferred to a storage location used for storing print processing data in client MFP 100c for each page. Therefore, first, as an initial condition, the page to be processed: n is set to “n ← 1” (step S201), and the server side document is copied to the client side page by page in order from page 1 (step S202).
Next, the client MFP 100c performs the printing process for the set number of sheets using the data of the first page of the document file copied to the storage location used for storing the print processing data (step S203).
After the printing process, the data of the first page copied to the client MFP 100c side is deleted in order to centrally manage the document file data on the server MFP 100s side and to save the storage capacity (step S204).
Next, in order to manage the printing process for each page, the page n to be processed is set to “n ← n + 1” (step S205), and the page n is checked whether or not the next page remains unprocessed (step S206). ). If there is an unprocessed page, the process returns to step S202 to perform the print process for the next page. If there is no unprocessed page, the process flow ends.
Note that the application that performs the printing process based on the data for each page in the above-described printing process is the same as the printing process using the copy function, and can be implemented by using the copy application.

"Remote Document Printing Process (III)"
The remote document print processing method of this embodiment selects data that matches the device conditions of the plotter that performs print processing when the data of the document file to be remotely accessed is filed in multiple data formats. By doing so, proper processing is possible.
FIG. 10 is a table showing an example of a file having a plurality of data formats. The table shown in the figure is a table in which file names shown to the user are associated with a plurality of actual file names. As shown in the display on the remote file access operation screen in FIG. 5, the file names shown to the user are shown as one file of report 01.tiff and report 02.pdf. Contains files with different data formats. In the example shown in FIG. 10, as shown in the remarks column of the table, the file data format is divided according to the difference between full color / monochrome and the resolution in the image data.
For example, when one of the files displayed on the operation screen is specified and printing processing is performed, if the data used for the processing is limited to one data format, depending on the plotter 134 on the client side, a color image can be supported. There are cases where the device conditions such as the resolution is different or the device conditions are not suitable, and the optimum operation is not performed. Therefore, in the present embodiment, it is possible to guarantee an optimum operation by selecting and accessing a file having a data format that is suitable in consideration of device conditions.

FIG. 11 shows a flowchart of the remote document printing process of this embodiment.
According to the processing flow of FIG. 11, when a user requests a document print process using the remote access function in the client MFP 100c, the server MFP 100s responds to the request and the document instructed as an access target from the document file stored in the HDD 122. Send the file. However, here, the document file instructed as an access target on the remote file access operation screen may actually consist of a plurality of data format files, and finally a file format suitable for print processing. A series of procedures are required until a document file to be accessed is specified.
As a procedure, first, based on the instructed document file name, a table as shown in FIG. 10 is referred to search for a file having a plurality of data formats registered with this file name (step S301).
Next, it is checked whether or not there are a plurality of files obtained as search results (step S302).
Here, if there is one searched file (step S302-NO), this file is immediately designated and a file data acquisition request is made, whereby the HDD 122 used for storing print processing data in the client MFP 100c. The file data is transferred to the storage location, and the document file on the server side is copied to the client side (step S303).

On the other hand, if there are a plurality of searched files (step S302-YES), a file having a format suitable for the printing process is selected from the plurality of files (step S304).
Here, examples of two methods of “color mode priority” and “resolution priority” are shown as methods that can be adopted in the file selection process (step S304).
“Color mode priority”
FIG. 12 shows a flowchart of a subroutine of file selection processing by the color mode priority method.
According to the processing flow of FIG. 12, first, it is checked whether the print mode setting of the MFP is color printing (step S401), and the processing is divided according to the check result.
If the color printing mode is set (step S401-YES), the existence of the file is checked in the order of “color” → “monochrome”, and the corresponding file is selected first (step S402). For resolution, priority is given to high resolution. In the case where the file data format is divided according to the difference between full color / monochrome and resolution (600dpi, 200dpi) in FIG. 10, for example, “color / 600dpi” → “color / 200dpi” → “monochrome / 600dpi” -> Search in the order of “black and white / 200dpi” and select the first searched file.
On the other hand, if the color printing mode is not set (step S401-NO), the files are searched in the order of “black and white” → “color”, and the corresponding file is selected first (step S402). In the case where the file data format is divided according to the difference between full color / monochrome and resolution (600dpi, 200dpi) in FIG. 10, for example, “color / 600dpi” → “color / 200dpi” → “monochrome / 600dpi” -> Search in the order of “black and white / 200dpi” and select the first searched file.
That is, in the color mode priority method, colors such as full color and black and white can be selected with priority on resolution.

“Resolution priority”
FIG. 13 shows a flowchart of a subroutine of file selection processing by the resolution priority method.
According to the processing flow of FIG. 13, first, it is checked whether the print mode setting of the MFP is color printing (step S501), and the processing is divided according to the check result.
If the color printing mode is set (step S501—YES), the existence of the file is checked in the order of “high resolution” → “low resolution”, and the corresponding file is selected first (step S502). Since the setting mode is given priority for the color, the color is given priority in this step. In the case where the file data format is divided by the difference between full color / monochrome and resolution (600dpi, 200dpi) in FIG. 10, for example, "600dpi / color" → "600dpi / monochrome" → "200dpi / color" → Searches in the order of “200dpi / white”, and selects the first searched file.
On the other hand, even when the color printing mode is not set (step S501-NO), files are searched in the order of “high resolution” → “low resolution”, and the corresponding file is first selected (step S402). As for color, priority is given to the setting mode, so black and white is given priority in this step. In the case where the file data format is divided by the difference in full color / monochrome and the resolution (600dpi, 200dpi) in FIG. 10, for example, “600dpi / monochrome” → “600dpi / color” → “200dpi / monochrome” -> Search in the order of "200dpi / color" and select the first file searched.
That is, in the resolution priority method, the resolution can be selected with priority over colors such as full color and black and white.

After the file selection process (step S304) is performed in the subroutine (FIG. 12 or FIG. 13), a file data acquisition request is made by remote access designating the selected file.
In response to this acquisition request, the file data is transferred to a storage location such as the HDD 122 used for storing print processing data in the client MFP 100c, and the server side document file is copied to the client side (step S305).
Next, the client MFP 100c performs print processing using the document file data copied to a storage location such as the HDD 122 (step S306).
After the printing process, the document file data copied to the client MFP 100c side is
The document file data is centrally managed on the server MFP 100s side, and is deleted in order to save the storage capacity (step S307), and this processing flow ends.
