For example, when receiving a print ID (reservation number), the printing apparatus 100 prints print image data corresponding to the reservation number. As an example, the printing apparatus 100 is installed in a convenience store, a supermarket, a hotel, a library, or the like. Note that the printing apparatus 100 may have a copy function and a facsimile function in addition to the print function.

  Next, the configuration of the print management apparatus 10 will be described.

  The preview request reception unit 12 receives information indicating a Web page print request from the terminal device 50.

  The program transmission unit 14 transmits the print image creation Web page data to the terminal device 50. The data of the print image creation Web page includes an encoding program for generating the encoding information for identifying the Web page to be printed by the terminal device 50. If the Web page to be printed is a dynamic Web page whose contents change every time it is accessed, or if it is an authentication Web page that requires authentication information for access, the program transmission unit 14 The print image creation Web page data including the recoverable encoding program is transmitted to the terminal device 50. The recoverable encoding program is a program for creating, in the terminal device 50, recoverable encoding information of the Web page to be printed. A web page other than the dynamic web page and the authentication web page is referred to as a static web page.

  The encoded information receiving unit 16 receives from the terminal device 50 address data (URL) of the Web page to be printed and the encoded information for identifying the Web page. When the print target Web page is a dynamic Web page or an authentication Web page, the encoding information receiving unit 16 includes the address data of the print target Web page, the encoded information for identifying the Web page, and the Web Coding information capable of restoring the page is received from the terminal device 50.

  The print image confirmation unit 18 determines whether or not the print data data identification information corresponding to the address data (URL) of the print target Web page transmitted from the terminal device 50 and the identification coding information is registered in the DB 80.

  When the print image data of the Web page to be printed is not stored in the print image storage device 90, the Web page acquisition unit 20 prints according to the address (URL) of the Web page to be printed transmitted from the terminal device 50. Web page data is acquired via the Internet N.

  The restoring unit 22 restores the data of the Web page to be printed from the recoverable encoded information transmitted from the terminal device 50.

  The print image creation unit 24 supports printing by the printing apparatus 100 based on the data of the print target web page acquired by the web page acquisition unit 20 or the print target web page restored by the restoration unit 22. Print image data expressed in the format to be created. The print image creation unit 24 creates identification information (name) and associates it with print image data. Further, the print image creation unit 24 creates the encoded information for identifying the Web page by encoding the Web page to be printed.

  The print information creation unit 26 creates print information indicating print conditions for print image data. For example, the print information includes a print ID (reservation number) of the print image data, a paper size, the number of prints, and a print fee.

  The print image transmission unit 28 transmits print image data and print information to the terminal device 50.

  As shown in FIG. 2 or 3, the print information management unit 30 includes address data (URL) of a Web page created in the past, encoded information for identifying the Web page, and print image data of the Web page.

  The print image request receiving unit 34 receives information (for example, a reservation number) indicating a print image data acquisition request from the printing apparatus 100.

  The print image transmission unit 36 transmits print image data corresponding to the reservation number to the printing apparatus 100.

  Next, a Web page displayed on the terminal device 50 will be described with reference to FIG. The site content (Web page) is displayed on the terminal device 50, and a print button is displayed in the site content. A URL for requesting printing is linked to the print button. The link URL includes the URL of the printer server (in this embodiment, the address of the print management apparatus 10 as an example), the URL of the Web page to be printed, and information (type information) indicating the type of the Web page to be printed. , Information (level information) indicating the strictness of the update determination of the Web page to be printed. When the user clicks the print button using the terminal device 50, a web page print request is made. Note that the URL of the Web page to be printed may be directly accessed without going through the print button. When a print layout page exists, the URL of the Web page to be printed may be the URL of the print layout page.

  The type information is information indicating which of the static web page, the dynamic web page, and the authentication web page the web page to be printed corresponds to. For example, a web page whose type is “1” is a static web page, and a web page whose type is “2” is a dynamic web page or an authentication web page. This type information is set by, for example, a Web page administrator.

  The level information is information for determining information to be included in the identification coding information when the identification coding information of the Web page to be printed is created. Specifically, whether the level information is identification coding information created from only the HTML of the Web page to be printed, including the CSS, Javascript of the link destination from HTML, and the image and HTML. This is information for deciding whether or not to create. For example, since CSS, Javascript, and images are links from HTML, even if these pieces of information are changed, the HTML itself is not changed, and therefore it is not possible to determine changes in these pieces of information from HTML. Therefore, when the link destination CSS, Javascript, and image have been changed, the level information is set so as to create the encoded information for identification including these information and HTML. For example, if the CSS, Javascript, and image of the link destination are not changed, the level is set to “1”, and if the information is changed, the level is set to “2”. Since the update of the Web page is managed by the administrator of the Web page, the level information is set by the administrator when the CSS, Javascript, and image of the link destination are changed. In this way, when a web page includes CSS, JavaScript, and images, and they are changed, the coding information for identification including CSS, Javascript, images, and HTML is created to change them. Identification coding information reflecting the above is created. In addition, when the file name is also changed along with the change of CSS, Javascript, and image, since the HTML is also changed, the level information may be set so that the identification encoded information is created only from the HTML. .

  FIG. 5 shows an example of a print image creation Web page. The print image creation Web page shown in FIG. 5 is transmitted to the terminal device 50 by the program transmission unit 14 and displayed on the terminal device 50. Print image data and print information transmitted from the print image transmission unit 28 to the terminal device 50 are displayed on the print image creation Web page. In addition, the program included in the print image creation Web page data may be used to acquire a Web page to be printed, create identification encoded information, and send identification encoded information to the print management apparatus 10. Done in the ground. For example, Ajax may be used for the background processing. The print image creation Web page corresponds to a preview screen of the Web page to be printed.

  Next, the configuration of the terminal device 50 will be described.

  For example, the control unit 52 activates a Web browser and causes the display unit of the UI unit 68 to display a Web page acquired by the Web browser. For example, the Web browser acquires Web page data via the Internet N according to an address (URL) designated by the user, and causes the UI unit 68 to display the Web page.

  When a web page print request is made by the user, the preview request transmission unit 54 transmits information indicating the print request for the web page to the print management apparatus 10. For example, as shown in FIG. 6, the preview request transmission unit 54 transmits the URL, type information, and level information of the Web page to be printed to the print management apparatus 10. Note that the preview request transmission unit 54 may not transmit the type information and the level information among the information illustrated in FIG. 6 to the print management apparatus 10.

  The program receiving unit 56 receives data of the print image creation Web page from the print management apparatus 10.

  The Web page acquisition unit 58 acquires data of a Web page to be printed via the Internet N.

  The encoding unit 60 generates encoded information for identifying the Web page by encoding the Web page to be printed. FIG. 7 shows an example of identification coding information. The identification encoded information is a hash value using MD5 (Message Digest Algorithm 5) as an example. In accordance with the level of the Web page, the Web page is encoded by combining the CSS, Javascript and image of the link destination, and HTML. For example, when the level is “1”, the encoding unit 60 creates encoded information for identification from HTML. If the level is “2”, the encoding unit 60 combines the CSS, Javascript and image of the link destination with HTML, and creates identification encoded information.

  When the Web page to be printed is a dynamic Web page or an authentication Web page, the recoverable encoding unit 62 generates encoded information that can be recovered by the print management apparatus 10 by encoding the Web page. . For example, since the Web page whose type is “2” is a dynamic Web page or an authentication Web page, the recoverable encoding unit 62 creates recoverable encoding information of the Web page whose type is “2”. . FIG. 8 shows an example of reconstructable encoded information. The reconstructable coding information is information created by BASE64 as an example.

  The encoded information transmission unit 64 transmits the identification encoded information created by the encoding unit 60 to the print management apparatus 10. In addition, the encoding information transmission unit 64 transmits the recoverable encoding information created by the recoverable encoding unit 62 to the print management apparatus 10. For example, when the Web page to be printed is a static page, the encoding information transmission unit 64, as shown in FIG. 9, the URL, type information, level information, and identification encoding information (enc) of the Web page to be printed. ) Is transmitted to the print management apparatus 10. When the print target Web page is a dynamic page or an authentication page, the encoding information transmission unit 64, as shown in FIG. 10, includes the URL, type information, level information, and identification encoding of the print target Web page. Information (enc) and recoverable encoded information (enc2) are transmitted to the print management apparatus 10. Note that the encoded information transmission unit 64 does not have to transmit type information and level information to the print management apparatus 10 among the information illustrated in FIGS. 9 and 10.

  The print image receiving unit 66 receives print image data and print information from the print management apparatus 10.

  The functions of the Web page acquisition unit 58, the encoding unit 60, the recoverable encoding unit 62, the encoding information transmission unit 64, and the print image reception unit 66 are realized by a program included in the print image creation Web page data. Is done. For example, the function of the encoding unit 60 is realized by an encoding program, and the function of the recoverable encoding unit 62 is realized by a recoverable encoding program.

  The user interface unit (UI unit) 68 includes an operation unit and a display unit, displays a web page, and receives information input by the user.

  Next, processing of the printing system according to the present embodiment will be described.

Example 1
Processing according to the first embodiment will be described with reference to the sequence diagram shown in FIG. In the first embodiment, a case where a Web page to be printed is a static Web page will be described.

  First, when the user instructs to start a Web browser using the UI unit 68 of the terminal device 50, the control unit 52 starts the Web browser and displays the Web page acquired by the Web browser on the display unit of the UI unit 68. (S01). For example, the Web browser displays the Web page illustrated in FIG. 4 on the display unit of the UI unit 68.

  When the user clicks the print button displayed on the Web page, the preview request transmission unit 54 prints the URL, type information, and level information of the Web page to be printed included in the link URL shown in FIG. A request is sent to the apparatus 10 to print a Web page (S02). FIG. 6 shows an example of the URL, type information, and level information transmitted to the print management apparatus 10. When the Web page to be printed is a static Web page, type is set to “1”.

  When the preview request reception unit 12 of the print management apparatus 10 receives a print request from the terminal device 50, the program transmission unit 14 transmits the data of the print image creation Web page to the terminal device 50 (S03). For example, when the type information indicates “1”, that is, when the Web page to be printed is a static Web page, the program transmission unit 14 stores the data of the print image creation Web page including the encoding program in the terminal To device 50.

  The program receiving unit 56 of the terminal device 50 receives the print image creation Web page data from the print management apparatus 10, and the control unit 52 displays the print image creation Web page on the display unit of the UI unit 68. Then, a program included in the print image creation Web page data is executed by the terminal device 50, so that the Web page acquisition unit 58, the encoding unit 60, the encoded information transmission unit 64, and the print image reception unit 66. Function is realized.

  First, the Web page acquisition unit 58 accesses the URL of the Web page to be printed and acquires the data of the Web page via the Internet N. The encoding unit 60 generates the encoded information for identification shown in FIG. 7 by encoding the Web page (S04). At this time, the encoding unit 60 may change the information to be encoded according to the set value of level. For example, when the level value is “1”, the CSS, Javascript, and image of the link destination have not been changed, so the encoding unit 60 creates identification encoded information from the HTML of the Web page to be printed. On the other hand, when the level value is “2”, the CSS, Javascript, and image of the link destination have been changed. Therefore, the encoding unit 60 combines the CSS, Javascript, image of the link destination, and HTML. Create identification coding information. Then, the encoding information transmission unit 64 transmits the URL, type information, level information, and identification encoding information (enc) of the Web page to be printed shown in FIG. 9 to the print management apparatus 10 (S05).

  The print image confirmation unit 18 of the print management apparatus 10 searches the DB 80 using the URL and identification encoded information transmitted from the terminal device 50 as search keys (S06).

  When the identification information of the print image data corresponding to the URL and identification encoded information transmitted from the terminal device 50 is registered in the DB 80, that is, the print image corresponding to the URL and identification encoded information. When the data is stored in the print image storage device 90 (S07, Yes), the print image transmission unit 28 acquires the print image data corresponding to the URL and the encoded information for identification from the print image storage device 90, and The print image data and print information are transmitted to the terminal device 50 (S13). Note that the print information is created by the print information creation unit 26.

  On the other hand, if the print image data corresponding to the URL and identification encoded information transmitted from the terminal device 50 is not stored in the print image storage device 90 (No in S07), the Web page acquisition unit 20 includes the URL. Access is made and data of the Web page to be printed is acquired via the Internet N (S08). The print image creation unit 24 creates coding information for identifying the Web page to be printed (S09), and creates print image data based on the data of the Web page (S10). In addition, the print information creation unit 26 creates print information. The print image management unit 32 stores the print image data created by the print image creation unit 24 in the print image storage device 90 (S11), and the print information management unit 30 prints as shown in FIG. 2 or FIG. The URL of the target Web page, the encoded information for identifying the Web page, and the print image data name of the Web page are associated with each other and stored in the DB 80 (S12). Then, the print image transmission unit 28 transmits the print image data and the print information to the terminal device 50 (S13).

  The print image receiving unit 66 of the terminal device 50 receives the print image data and the print information from the print management device 10, and the control unit 52 receives the print image data and the print information as shown in FIG. It is displayed in the web page (S14).

  When the user inputs a reservation number displayed as print information to the printing apparatus 100, the printing apparatus 100 transmits information (for example, a reservation number) indicating a print target data acquisition request to the print management apparatus 10. The print image request reception unit 34 of the print management apparatus 10 receives information indicating the acquisition request, and the print image transmission unit 36 acquires print image data corresponding to the reservation number from the print image storage device 90 and prints the print device. To 100. The printing apparatus 100 prints the print image data transmitted from the print management apparatus 10.

  According to the first embodiment, the print image data of the Web page is associated with the identification encoding information and managed in the DB 80, and is the same as the identification encoding information of the Web page to be printed created by the terminal device 50. Is stored in the DB 80, the print management device 10 transmits the print image data stored in the print image storage device 90 to the terminal device 50 and the printing device 100, and identifies the Web page to be printed. When the same information as the encoded information is not stored in the DB 80, the print management apparatus 10 acquires the data of the Web page to be printed and creates print image data, thereby increasing the load on the print management apparatus 10 Is prevented or reduced. That is, when the same information as the identification encoded information created by the terminal device 50 is stored in the DB 80, print image data of a Web page having the same URL as the URL of the Web page to be printed is created in the past. The content of the Web page has not been changed since the past creation time. In other words, the Web page to be printed has not been updated. In this case, the print management apparatus 10 does not create new print image data of the Web page to be printed, but transmits the print image data stored in the print image storage device 90 to the printing apparatus 100. As described above, when the Web page to be printed has not been updated, printing using the print image data stored in the print image storage device 90 prints the acquisition of the Web page and the creation of the print image data. Since there is no need for the management apparatus 10 to perform, an increase in the load of the print management apparatus 10 is prevented or reduced, and the time required for acquiring Web page data is reduced. Therefore, a decrease in Web page printing efficiency is prevented or reduced.

  On the other hand, when the same URL as the URL of the Web page to be printed is stored in the DB 80, print image data of the Web page to be printed has been created in the past. If the identification coding information created in this way does not match the identification coding information stored in the DB 80, the contents of the Web page to be printed have been changed from the past creation time. . That is, the Web page to be printed has been updated. In this case, the print management apparatus 10 obtains the latest information of the Web page by accessing the URL of the Web page to be printed, and creates updated print image data based on the latest information. Even if the URL of the Web page does not change, if the content of the Web page is updated, the encoded information for identification of the Web page is different before and after the update. By managing this, it is confirmed whether or not the Web page has been updated. When the update is confirmed, the print management apparatus 10 acquires the data of the Web page and creates print image data. As described above, when the Web page to be printed is updated, the data of the Web page is acquired and print image data is created. When the Web page is not updated, the print image created in the past is acquired. By using the data for printing, it is possible to prevent or reduce a decrease in Web page printing efficiency.

  For example, when printing the same Web page a plurality of times, if print image data is created, the print management apparatus 10 does not need to acquire the data of the Web page to be printed each time. Is prevented or reduced.

  Also, a program for creating identification encoded information in the terminal device 50 and transmitting it to the print management device 10 is transmitted from the print management device 10 to the terminal device 50 together with the data of the print image creation Web page. Therefore, a dedicated program for creating and transmitting identification coding information need not be installed in the terminal device 50 in advance.

  In addition, even when the link destination CSS, Javascript, and image from HTML are changed, by creating the encoded information for identification using the level information, whether or not the Web page has been changed is more accurate. To be confirmed.

(Example 2)
Next, processing according to the second embodiment will be described with reference to the sequence diagram shown in FIG. In the second embodiment, a case where the Web page to be printed is a dynamic Web page or an authentication Web page will be described.

  Similar to the first embodiment, the control unit 52 activates the web browser and causes the UI unit 68 to display the web page acquired by the web browser (S20). When the user clicks the print button displayed on the Web page, the preview request transmission unit 54 transmits the URL, type information, and level information of the Web page to be printed to the print management apparatus 10 to print the Web page. Is requested (S21). In response to this, the program transmission unit 14 of the print management apparatus 10 transmits the data of the print image creation Web page to the terminal device 50 (S22). For example, when the type information indicates “2”, that is, when the Web page to be printed is a dynamic Web page or an authentication Web page, the program transmission unit 14 selects an encoding program and a recoverable encoding program.

  As in the first embodiment, when the user inputs a reservation number displayed as print information to the printing apparatus 100, the printing apparatus 100 receives print image data corresponding to the reservation number from the print management apparatus 10. Print.

  According to the second embodiment, similarly to the first embodiment, by storing the print image data of the Web page in the print image storage device 90, an increase in the load on the print management device 10 is prevented or reduced, and the Web page A decrease in printing efficiency is prevented or reduced.

  Even if print image data identical to the print image data of the print target Web page has not been created in the past, the Web page is a dynamic Web page whose contents can be changed each time it is accessed. The terminal device 50 creates decodable encoded information of the Web page to be printed, and the print management apparatus 10 decodes the print image data with the same content as the user requested to print. Is done.

  Even if the print management apparatus 10 accesses the URL of the Web page to be printed and acquires the Web page data, the contents of the Web page may have been changed since the terminal apparatus 50 accessed. Therefore, the content of the Web page acquired by the print management apparatus 10 may be different from the content of the Web page acquired by the terminal device 50, that is, the content of the Web page to be printed. In this case, since the Web page different from the content requested by the user is acquired by the print management apparatus 10, the content requested by the user is not printed. On the other hand, according to the second embodiment, the same information as that requested by the user is created by generating the reconstructed encoded information of the Web page to be printed by the terminal device 50 and transmitting it to the print management device 10. The print management data 10 is created by the print management apparatus 10.

  When the print target web page is an authentication web page, the print management apparatus 10 acquires information (for example, a password) necessary for authentication in order to acquire the print target web data and create print image data. It is necessary to provide it to the print management apparatus 10. In the second embodiment, encoding information that can be encoded for a Web page to be printed is generated by the terminal device 50 and decoded by the print management device 10, thereby printing the same print image data as the authentication Web page. Even if the image data has not been created in the past, print image data having the same content as the content requested by the user is created.

  Even if the Web page to be printed is a static Web page, the terminal device 50 generates encoding information that can be restored for the Web page, and the printing information that can be restored by the print management apparatus 10. And print image data may be created based on the restored Web page.

  In addition, print image data may be managed using recoverable encoding information instead of the identification encoding information. In this case, instead of the identification encoding information shown in FIGS. 2 and 3, recoverable encoding information is managed in association with the URL and the name of the print image data.

  Also, the print management apparatus 10 specifies a print ID (reservation number) corresponding to the encoded information for identifying the Web page to be printed based on the correspondence shown in FIG. 3, and a print image corresponding to the print ID Data may be acquired from the printing apparatus 100.

  The print management apparatus 10 described above is realized by cooperation of hardware resources and software as an example. Specifically, the print management apparatus 10 includes a processor such as a CPU (not shown). The function of each unit of the print management apparatus 10 is realized by the processor reading and executing a program stored in a storage device (not shown).
