  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

[Background of the invention]
There has been commercialized an image forming apparatus that is equipped with a web browser and that can directly print a file transmitted from an external server on the network when the web browser determines that the file can be printed. Usually, a web browser acquires display data described in HTML (HyperText Markup Language) from an external server, analyzes it, and displays the result on the display unit. Also, by operating display parts such as buttons and text, a file is obtained from a URL (Uniform Resource Locator) that is the access destination of the server described in the display data, and information on the file sent from the server (MIME type) Process the file accordingly. For example, if the file information indicates HTML, the syntax is analyzed and the result is displayed. If the file information indicates JPEG, the JPEG image is decompressed and the result is displayed. At this time, if the file information indicates a file that can be printed by the image forming apparatus, a screen for setting printing conditions such as the paper size and the number of copies is displayed, and the file is printed according to a user instruction.

  In this case, the following method can be considered as a method for specifying the file name.

  The first method is to use a URL that is an access destination of the server.

  The URL is defined in RFC3986, and a code in the form of “% xx” (xx is a hexadecimal number) is written in place of characters in order to express a Japanese file name or the like. For example, the URL of “Japan.pdf” is not “http: //domain/file/Japan.pdf” but “http: // domain / file /% E6% 97%” if expressed in UTF-8 encoding. A5% E6% 9C% AC.pdf ". However, when a file name is expressed in a local language, there is no regulation as to what kind of encoding is used, and it is currently different depending on the operating environment.

  The URL of a CGI (Common Gateway Interface) that dynamically generates and returns a file is, for example, “http: //domain/createFile.cgi”, and the file name of the generated file cannot be expressed.

  Further, depending on the file configuration in the server, for example, a URL such as “http: // domain / dir / files /” may be designated. In this case, a mechanism for returning the default file in the hierarchy on the server side is generally prepared, but it is difficult to specify the file name from the URL.

  The second method uses a Content-Disposition (RFC 1806) header.

  In this method, the filename attribute of the Content-Disposition header transmitted from the server is used as the file name. However, since the filename attribute is limited to the ASCII character string, only alphanumeric file names can be used. In other words, this method has a limitation that the file name of the local language cannot be used.

  Therefore, in this embodiment, when a file transmitted from an external server on the network is acquired and printed, a file name that can be expressed in a local language such as Japanese can be specified and used.

[Operation of this embodiment]
First, the operation of the image forming apparatus 10 will be described. When activated, the image forming apparatus 10 displays a menu screen illustrated in FIG. 6 on the operation panel 15. Of the buttons displayed on the menu screen, an “external access” button is a button that is pressed when accessing a connection destination registered in the image forming apparatus 10.

  Here, the image forming apparatus 10 registers the connection destination to the “external access” button as follows. That is, when the “specification setting / registration” button on the menu screen of FIG. 6 is pressed, the image forming apparatus 10 displays a connection destination registration screen illustrated in FIG. In this registration screen, “external access server” corresponds to the connection destination. Here, a maximum of 10 connection destinations can be registered. Next, when “external access server 1” is selected and the “setting” button is pressed, the image forming apparatus 10 displays a setting screen related to “external access server 1” illustrated in FIG. . Then, the URL of the connection destination is registered on this setting screen. In the present embodiment, for each “external access server”, a button for accessing the “external access server” can be arranged on the menu screen of FIG.

  When the URL of the “external access server” is registered in the image forming apparatus 10 in this way, the image forming apparatus 10 starts the operation of the present embodiment. FIG. 9 is a flowchart showing a flow of main processing in the operation example of the present embodiment.

  When the “external access” button on the menu screen of FIG. 6 is pressed, the communication control unit 21 accesses the registered URL (step 101). As a result of the access, a file is returned from the server 30, and the communication control unit 21 receives this file (step 102). Normally, an HTML file is returned first, and as a result of analyzing the HTML file, an image file attached to the HTML file or a program written in the JavaScript (registered trademark) language is accessed by accessing the URL specified in the HTML file. Files etc. are returned. Then, the communication control unit 21 performs reception information analysis processing for analyzing the received information (step 103). Thereafter, the communication control unit 21 determines whether or not all the files constituting one screen (page) have been received (step 104), and returns to step 102 if it is determined that all the files have not been received. .

  On the other hand, if it is determined that all files have been received, the display control unit 23 controls the file list screen illustrated in FIG. 10 to be displayed on the operation panel 15 (step 105). At this time, on the file list screen, the file name acquired in step 204 described later is displayed for each file. In this state, the operation reception unit 22 monitors the user's operation and determines whether or not the user has operated the touch panel (step 106). If it is not determined that the user has operated the touch panel, the operation accepting unit 22 repeats step 106. If it is determined that the user has operated the touch panel, the communication control unit 21 determines that the file to be operated. The URL defined by the link corresponding to is accessed (step 107). As a result of the access, a file is returned from the server 30. Therefore, the communication control unit 21 receives this file (step 102) and performs received information analysis processing (step 103).

  Here, the file list screen of FIG. 10 will be described in more detail. As shown in the drawing, each line of the file list screen displays the file name, owner, update date / time, size, and the like of the file to be printed. In the present embodiment, since the PDF file and the TIFF file are the print target files, the extension of all the file names is either “.pdf” or “.tif”. Further, on the left side of the file name, an icon for distinguishing the PDF file and the TIFF file is displayed, and on the further left side, a radio button for selecting a file to be printed is displayed. In other words, a desired print target file is selected by pressing a radio button, and when the “Print” button is pressed, the print target file is transmitted from the server 30.

  FIG. 11 is a flowchart showing a flow of received information analysis processing in step 103 of FIG. Normally, HTTP (HyperText Transfer Protocol) is used for communication with the server 30. In HTTP, information is set in the Content-Type header to indicate the type of file sent from the server 30. Specifically, the MIME type shown in FIG. 12 is set in this header.

  If “text / html” is set in the Content-Type header sent from the server 30, the received information is an HTML file, so the communication control unit 21 sets “text / html” in the Content-Type header. By determining whether or not the received information is an HTML file, it is determined (step 201). If it is determined that the received information is an HTML file, the display control unit 23 analyzes the HTML file to generate display data, and controls the display data to be displayed on the operation panel 15 (step 202). Further, the communication control unit 21 accesses the URL described in the HTML file, acquires other information (image file, program file, etc.) attached to the HTML file, and the display control unit 23 operates this information as well. Control is performed so as to be displayed on the panel 15 (step 203). Thereafter, the file name acquisition unit 24 executes a first file name acquisition process based on the HTML information analyzed by the communication control unit 21, and the acquired file name is stored in the management table storage unit 26. The file is stored in the file name management table (step 204).

  Further, if “image / jpeg”, “image / png”, “image / bmp”, etc. are set in the Content-Type header sent from the server 30, the received information is an image file. It is determined whether the received information is an image file by determining whether “image / jpeg”, “image / png”, “image / bmp”, etc. are set in the Content-Type header (step 205). ). If it is determined that the received information is an image file, the display control unit 23 analyzes the image file to generate display data, and controls the display data to be displayed on the operation panel 15 (step 206).

  Furthermore, in the present embodiment, if “application / pdf” or “image / tiff” is set in the Content-Type header sent from the server 30, the received information is a print target file, so the communication control unit 21 Determines whether the received information is a file to be printed by determining whether “application / pdf” or “image / tiff” is set in the Content-Type header (step 207). If it is determined that the received information is a file to be printed, the file name acquisition unit 24 executes a second file name acquisition process, and the acquired file name is stored in the management table storage unit 26 as a file name management unit. The table is held (step 208). Thereby, the file name determination unit 27 determines the final file name based on the file names held in the file name management table in the first file name acquisition process and the second file name acquisition process. Processing is executed (step 209). Finally, the printing condition setting unit 28 and the printing instruction unit 29 execute the printing process (step 210).

  Furthermore, in the present embodiment, if “application / fname” is set in the Content-Type header sent from the server 30, the received information is a file name description file. By determining whether “application / fname” is set in the Type header, it is determined whether the received information is a file name description file (step 211). If it is determined that the received information is a file name description file, the file name acquisition unit 24 registers the file name described in the file name description file in the file name management table stored in the management table storage unit 26. (Step 212). Here, the file name description file may be one in which the file name is described by a character string, or may be one in which the file name is defined by XML (eXtensible Markup Language) or the like.

  FIG. 13 is a diagram showing a file name management table in which file names are registered in this way. Note that the file described as “External” in the “Type” column corresponds to the file in which the file name described in the file name description file is registered.

  FIG. 14 is a flowchart showing the flow of the first file name acquisition process in step 204 of FIG.

  As shown in the figure, first, the file name acquisition unit 24 analyzes the syntax of the HTML file (step 221). Then, from the analysis result of the HTML file, the server access tag defined to access the server 30 according to the user's operation is referred to (step 222). In the following description, an A tag and a FORM tag are illustrated as server access tags, but are not limited to these tags.

  Next, the file name acquisition unit 24 determines whether a file name is specified as the attribute value of the server access tag (step 223). For example, in the description “<A HREF=”../../file/print” printFileName=”document1.pdf”> Click here! </A>”, the file name “document1” is set as the attribute value “printFileName”. Since “.pdf” is designated, the file name acquisition unit 24 determines that the file name is designated as the attribute value of the server access tag. In this case, the file name designated as the attribute value is registered in the file name management table of FIG. 13 (step 224). It should be noted that the file described as “HTML-Attribute” in the “Type” column in FIG. 13 corresponds to the file in which the file name is registered.

  Further, the file name acquisition unit 24 determines whether or not a file name acquisition destination is specified as the attribute value of the server access tag (step 225). For example, in the description “<FORM ACTION =” ../../ file / print ”printRemoteFileName =” ../ print / fileA ”> </ FORM>”, the file name is acquired as the value of the attribute “printRemoteFileName” Since the destination “../print/fileA” is specified, the file name acquisition unit 24 determines that the acquisition destination of the file name is specified as the attribute value of the server access tag. In this case, the file name acquisition destination is accessed (step 226). When accessing the file name acquisition destination in this way, a file name description file is sent from the server 30. As a result, the communication control unit 21 receives the file name description file in step 102 of FIG. 9, and the file name acquisition unit 24 sets the file name described in the file name description file in step 212 of FIG. Register in the name management table.

  Furthermore, the file name acquisition unit 24 determines whether or not a function for acquiring a file name is specified as the attribute value of the server access tag (step 227). For example, in the description “<FORM ACTION =” ../../ file / print ”onprint =” getFileName () ”> </ FORM>”, the function “getFileName” is used as the value of the attribute (event handler) “onprint” Since “()” is specified, the file name acquisition unit 24 determines that the function is specified as the attribute value of the server access tag. In this case, this function is executed, and the character string obtained as the return value is registered as a file name in the file name management table of FIG. 13 (step 228). It should be noted that the file indicated as “onprint” in the “type” column in FIG. 13 corresponds to the file in which the file name is registered.

  On the other hand, when the file name acquisition unit 24 determines that none of the file name, the acquisition destination of the file name, and the function for acquiring the file name are specified as the attribute value of the server access tag, the server access tag The URL designated as the value of the tag attribute is analyzed, and the file name obtained from the analysis result is registered in the file name management table of FIG. 13 (step 229). Note that the URL is defined in RFC 1738. According to this, in order to specify the file name from the URL, it is considered that the character string after the last symbol “/” is handled as the file name.

  However, for example, it is difficult to specify a file name from the following URL. In other words, a URL that does not have a file name designation part such as “http: // host / dir / dir /”, and a file is dynamically created such as “http: //host/dir/file.cgi” URL indicating a program such as CGI to be executed, URL indicating a program and an argument to the program such as “http: //host/dir/file.pl? Name = aaa”, and the like. When the URL is such, although not shown in FIG. 14, the file name acquisition unit 24, for example, based on the current time (year / month / day / hour / minute / second) information, “20130617233245”, “20130617233245_unkown” , “20130617233245_host_dir_unkown_file” is desirable. The file name acquisition unit 24 also registers the file name obtained by analyzing the URL in this way in the file name management table of FIG.

  Thereafter, the file name acquisition unit 24 determines whether all server access tags have been referred to from the analysis result of the HTML file (step 230). If it is determined that all server access tags have not been referenced, the process returns to step 222. If it is determined that all server access tags have been referenced, the process returns to FIG.

  FIG. 15 is a flowchart showing the flow of the second file name acquisition process in step 208 of FIG.

  As shown in the figure, first, the file name acquisition unit 24 determines whether or not the HTTP header received together with the print target file by the communication control unit 21 in step 102 of FIG. 241). If it is determined that the Content-Disposition header is included, the character string after “filename =” is registered as a file name in the file name management table of FIG. 13 (step 242).

  In addition, the file name acquisition unit 24 uses a header (hereinafter referred to as “file name designation”) specially prepared for designating a file name in the HTTP header received together with the print target file by the communication control unit 21 in step 102 of FIG. It is determined whether or not a header is included (step 243). If it is determined that the file name designation header is included, the file name obtained from the file name designation header is registered in the file name management table of FIG. 13 (step 244). At this time, the server 30 transmits a file name designation header in which a character string obtained by encoding the UTF-8 file name in BASE64 is set, and the file name acquisition unit 24 uses the character string set in the file name designation header as BASE64. It is desirable to decode to obtain a UTF-8 file name. However, the encoding / decoding method and the character code of the file name are not limited to this, and an encoding / decoding method other than BASE64 or a character code other than UTF-8 may be used.

  Furthermore, if the file name acquisition unit 24 determines that the file name is not specified in the HTTP header received together with the print target file by the communication control unit 21 in step 102 of FIG. 9, the file name acquisition unit 24 can analyze the print target file. It is determined whether or not there is (step 245). If it is determined that the print target file can be analyzed, the print target file is analyzed, and the file name obtained from the analysis result is registered in the file name management table of FIG. 13 (step 246). For example, in the PDF defined by ISO 32000, the value of the “Key = Name” attribute is defined as the file name. Accordingly, while receiving the print target file sent from the server 30, the analysis is continued until the value of the “Key = Name” attribute is found, and the file name specified as the value of the “Key = Name” attribute is acquired. The file name is registered in the file name management table of FIG. In general, it takes a certain amount of time to analyze the file to be printed, but in this embodiment, the analysis is continued until the file name can be acquired, and the next-stage file name determination process is waited. If it is determined that the file to be printed is not analyzable, the file name acquisition unit 24 advances the processing to step 247 without registering the file name in the file name management table.

  Thereafter, the authentication unit 25 determines whether or not the user has been authenticated (step 247). For example, the user ID read by the IC card reader 16 is received from the IC card possessed by the user, and the user ID is verified with the user ID registered in advance, and the authentication information is provided to the file name acquisition unit 24. Determine whether you are doing. As a result, if the authentication unit 25 determines that the user has been authenticated, the file name acquisition unit 24 is based on, for example, authentication information and information on the current time (year / month / day / hour / minute / second) at that time. Then, file names such as “user name_20130617233245” and “department_user name_20130617233245” are generated and registered in the file name management table of FIG. 13 (step 248). On the other hand, if the authentication unit 25 determines that the user has not been authenticated, the file name acquisition unit 24 returns the processing to FIG.

  FIG. 16 is a flowchart showing the flow of the file name determination process in step 209 of FIG.

  As shown in the figure, first, the file name determination unit 27 reads all lines related to the print target file received by the communication control unit 21 in step 102 of FIG. 9 from the file name management table stored in the management table storage unit 26. Read (step 261).

  Next, the file name determination unit 27 determines whether or not the file name included in the read line is specified in the HTML file (step 262). If it is determined that the file name is specified in the HTML file, it is determined to use the file name specified in the HTML file (step 263). Here, it is determined that the file name is specified in the HTML file when the “type” in the read line is “HTML-Attribute” or “onprint” shown in FIG. is there.

  Further, the file name determination unit 27 determines whether or not the file name included in the read line is clearly indicated in the HTTP header (step 264). If it is determined that the file name is specified in the HTTP header, it is determined to use the file name specified in the HTTP header (step 265). Here, it is determined that the file name is clearly specified in the HTTP header when the “type” in the read line is “Content-Disposition” shown in FIG. 13 or shown in FIG. This is a case where the information is a file name designation header.

  Further, the file name determination unit 27 determines whether or not the file name included in the read line is clearly indicated in the print target file (step 266). If it is determined that the file name is specified in the print target file, it is determined to use the file name specified in the print target file (step 267). Here, it is determined that the file name is specified in the print target file when the “type” in the read line is not shown in FIG. 13 but is information representing the print target file. It is.

  Furthermore, the file name determination unit 27 determines whether or not the file name included in the read line is specified in the file name description file (step 268). If it is determined that the file name is specified in the file name description file, it is determined to use the file name specified in the file name description file (step 269). Here, it is determined that the file name is specified in the file name description file when the “type” in the read line is “External” shown in FIG.

  Next, the file name determination unit 27 determines whether the file name included in the read line is generated from the authentication information (step 270). As a result, if it is determined that the file name is generated from the authentication information, it is determined to use the file name generated from the authentication information (step 271). On the other hand, when it is determined that the file name is not generated from the authentication information, if the file name is not generated only from the current time, the file name is specified in the URL. . Therefore, in this case, it is determined to use the file name specified in this URL (step 272).

  Thereafter, the file name determination unit 27 returns the processing to FIG.

  In this embodiment, the file name included in the read line is specified in the HTML file, specified in the HTTP header, specified in the print target file, or specified in the file name description file. In this order, the determination is made in the order of whether the information is specified in the above or generated from the authentication information, but this is not restrictive. For example, the determination from the first to the fourth may be reversed.

  FIG. 17 is a flowchart showing the flow of the printing process in step 210 of FIG.

  As shown in the figure, first, the display control unit 23 performs control so that the print condition setting screen illustrated in FIG. 18 is displayed on the operation panel 15 (step 281). Then, according to the operation on the print condition setting screen by the user, the print condition setting unit 28 sets print conditions such as a paper tray, a discharge destination, and a color (step 282). Further, as shown in FIG. 18 as “file name: MOV01045.MPG”, the file name determined in the file name determination process is displayed on the print condition setting screen, so that the user can confirm the file name. Also do.

  In this state, the operation reception unit 22 monitors the user's operation and determines whether or not the user has pressed the “print” button (step 283). If it is determined that the user has pressed the “print” button, the communication control unit 21 downloads the file to be printed (step 284), and the display control unit 23 operates the download status screen illustrated in FIG. Control is performed so as to be displayed on the panel 15 (step 285). Here, the file name and download status of the file to be printed are displayed on this download status screen. Note that when the communication control unit 21 accesses the URL in step 107 of FIG. 9, the download of the print target file has started, but if the size of the print target file is large, a print condition setting screen is displayed. Even if the file name is displayed on the print condition setting screen, the download is not necessarily completed. Therefore, in this operation example, in step 284, the download target file is continuously downloaded. However, if the download is complete because the size of the file to be printed is small, step 284 and step 285 do not have to be executed.

  If it is not determined that the user has pressed the “print” button, the operation accepting unit 22 determines whether the user has pressed the “cancel” button (step 286). If it is determined that the user has pressed the “cancel” button, the print condition setting screen is closed and the process returns to FIG.

  On the other hand, if it is not determined that the user has pressed the “cancel” button, the operation accepting unit 22 determines whether or not the user has performed an operation of inputting that the file name is changed (step 287). If it is determined that the user has entered an operation to change the file name, the display control unit 23 controls the virtual keyboard to be displayed on the operation panel 15, and the operation reception unit 22 Accepts an operation to change the file name (step 288), and repeats the processing after step 283. If it is not determined in step 287 that the user has performed an operation to input that the file name is to be changed, the processes in and after step 283 are repeated without changing the file name.

  Thereafter, the communication control unit 21 determines whether or not the download of the print target file is completed (step 289). If it is determined that the download of the print target file has been completed, the print instruction unit 29 instructs the image forming unit 17 to print the print target file under the print conditions set in step 282 (step 290). ).

  On the other hand, if it is not determined that the download of the print target file has been completed, the operation reception unit 22 determines whether the user has pressed the “stop” button (step 291). If it is determined that the user has pressed the “stop” button, the communication control unit 21 stops downloading the print target file (step 292), and returns the process to FIG. If it is not determined in step 291 that the user has pressed the “stop” button, the processes in and after step 289 are repeated.

  Next, the operation of the server 30 will be described. Here, it is assumed that the HTML file, the file to be printed, and the file name description file are stored in a complete state (in a state where they can be transmitted as they are and can be used in the image forming apparatus 10).

  FIG. 20 is a flowchart showing a flow of processing when the server 30 transmits a file.

  When there is an access from a web browser installed in the image forming apparatus 10, in the server 30, the receiving unit 41 receives information indicating the location where the access has been made (step 301).

  Next, the file acquisition unit 42 acquires a file from the location indicated by the received information (step 302). For example, when the image forming apparatus 10 accesses the server 30 in step 101 of FIG. 9, since the HTML file should be stored at the location where the access has been made, the file acquisition unit 42 acquires the HTML file. Further, when the image forming apparatus 10 accesses the server 30 in step 107 of FIG. 9, since the print target file and the like should be stored at the location where the access has been made, the file acquisition unit 42 sets the print target file and the like. To get. Furthermore, when the image forming apparatus 10 accesses the server 30 in step 226 in FIG. 14, the file name description file should be stored at the location where the access has been made. To get. Then, the file acquired in this way is transferred to the transmission unit 43.

  Then, the transmission part 43 produces | generates the communication information transmitted to the image forming apparatus 10 with the file acquired by the file acquisition part 42 (step 303). At that time, the server 30 sets information relating to the file name in the communication information in accordance with the setting of the accessed location.

  Specifically, first, the transmission unit 43 determines whether or not the accessed location is set to transmit a Content-Disposition header (step 304). If it is determined that the accessed location is set to transmit the Content-Disposition header, the file name of the file acquired in step 302 is set in the filename attribute of the Content-Disposition header of the HTTP header ( Step 305). Here, it is assumed that when a print target file is stored at a location where access has been made, the location is set to transmit a Content-Disposition header. The file name set in the filename attribute of the Content-Disposition header may be arbitrarily determined by the user and stored in a predetermined storage area of the server 30.

  Next, the transmission unit 43 determines whether or not the location where access has been made is set to transmit a file name designation header (step 306). If it is determined that the location where the access has been made is set to transmit the file name designation header, the file name of the file acquired in step 302 is set in the file name designation header of the HTTP header (step 307). . Here, it is assumed that when a file to be printed is stored at a location where access has been made, the location is set to transmit a file name designation header. The file name set in the file name designation header may be arbitrarily determined by the user and stored in a predetermined storage area of the server 30.

  Thereafter, the transmission unit 43 uses the file acquired in step 302 and the communication information generated in step 303 (the communication information after the additional setting in step 305 or step 307) as the image forming apparatus 10. (Step 308).

[Modification]
In the present embodiment, the file name acquisition unit 24 executes the first file name acquisition process and the second file name acquisition process, and the file name determination unit 27 finally selects from the file names acquired by these processes. The file name acquisition unit 24 executes only one of the first file name acquisition process and the second file name acquisition process, and the file name determination unit 27 is executed. The final file name may be determined from the file names acquired by the processing.

  In this embodiment, it is assumed that the server 30 stores an HTML file, a print target file, and a file name description file. However, when the image forming apparatus 10 acquires the file name of the print target file, the file name If no description file is used, the server 30 may not store a file name description file.

  The program for realizing the present embodiment can be provided not only by communication means but also by storing it in a recording medium such as a CD-ROM.
