BACKGROUND
The present invention relates to a mobile terminal, a printing system, and a printing method. In particular, the present invention relates to a mobile terminal, a printing system and a printing method that acquire printing images from an image storage server.
In the past, a telephone is known in which image data input to a slave unit are transmitted to a master unit by means of a radio communication means and the image data are printed using a printing device installed in the master device (see Patent Document 1, for example).

    Patent Document 1: Japanese Patent Publication No. 2005-348085A


However, according to the technology of Patent Document 1, when the image data are input to the slave unit, the slave unit identifies the image data to determine whether the image data will be transmitted to the master unit. Therefore, in the technology of Patent Document 1, the image data that need not be transmitted to the master unit are input to the slave unit. When the technology is used in paid services that charge for each image data, there is a problem that the image data that are not printed in the master unit are also charged.

The mobile terminal network transceiver 210 of the mobile terminal 20 acquires the identification information stored in the identification information storage 250 of the mobile terminal 20 and transmits an image transmission request for requesting the printing images containing the identification information and user information to the server network transceiver 310 of the server 30 (S250). The user information is information that specifies the mobile terminal 20 or the user of the mobile terminal 20 and may be MSISDN (Mobile Subscriber ISDN Number) or IMSI (International Mobile Subscriber Identity).
The server network transceiver 310 of the server 30 transmits the printing sages stored in the image storage 350 in a correlated manner with the identification information contained in the image transmission request to the mobile terminal network transceiver 210 of the mobile terminal 20 (S330). The mobile terminal network transceiver 210 of the mobile terminal 20 sends the received printing images to the mobile terminal local area transceiver 220 of the mobile terminal 20 via the input reception unit 200 of the mobile terminal 20.
The mobile terminal local area transceiver 220 of the mobile terminal 20 transmits the sent printing images to the printer local area transceiver 420 of the printer 40 (S255). The printer local area transceiver 420 of the printer 40 transmits end-of-job information representing that the printer 40 has received the printing images to the mobile terminal local area transceiver 220 of the mobile terminal 20 (S420). The printer local area transceiver 420 of the printer 40 also sends the received printing images to the printing unit 430 of the printer 40. The printer local area transceiver 420 of the printer 40 performs printing by outputting the sent printing images on a print sheet (S430).
The mobile terminal local area transceiver 220 of the mobile terminal 20 sends the received end-of-job information to the input reception unit 200 of the mobile terminal 20. The input reception unit 200 of the mobile terminal 20 transmits the end-of-job information to the server network transceiver 310 of the server 30 (S260). The input reception unit 200 of the mobile-terminal 20 displays that the printer 40 has received the printing images (S265). Specifically, a page shown in FIG. 3(g) for displaying that the printer 40 has received the printing images is displayed (s265).
The server network transceiver 310 of the server 30 sends a notification that it has received the end-of-job information to a billing unit (not shown). Then, the billing unit charges payment for the transmission of the printing images transmitted in Step S330 in a correlated manner with the user information received in Step S250 (S340). In this way, the flow chart completes.
According to the flow chart described above, it is possible to acquire image data optimal to the printer 40 and perform printing based on the optimal image data. For example, among the image data of the same contents of which the resolution or tone is different, image data that is optimal to the kind of the printer 40 is acquired and printing is performed based on the optimal image data. According to the flow chart, the mobile terminal 20 acquires the identification information request immediately before the list of the printing images is acquired and before the printing images are acquired, that is, before the printing images are printed. With this configuration, it is possible to securely specify the printer 40, which is a counterpart of the transmission. In addition, even when the printing is performed using a printer 40 that is different from the printer 40 of which the identification information has been acquired during the acquisition of the list, it is possible to, acquire the printing images that are optimal to the printer 40 for use in the printing.
In the flow chart described above, although the mobile terminal 20 acquires the identification information request immediately before the list of the printing images is acquired (Steps S205 and S400), these steps may be omitted. As an example, subsequent to Step S200, the input reception unit 200 of the mobile terminal 20 may acquire the identification information stored during the previous acquisition in the identification information storage 250 and transmit a list transmission request containing the identification information to the server network transceiver 310 of the server 30 (S210). As another example, subsequent to Step S200, the input reception unit 200 of the mobile terminal 20 may not acquire the identification information and transmit a list transmission request without containing the identification information to the server network transceiver 310 of the server 30 (S210).
In the embodiment described above, although the mobile terminal 20 has the screen storage 260 and the input reception unit 200 of the mobile terminal 20 displays the pages stored in the screen storage 260, the invention is not limited to this. As an example, the server 30 may store all or parts of the pages and the input reception unit 200 of the mobile terminal 20 may acquire the pages from the server 30 and display the pages. When storing the page for receiving the print setting input of the printing images, it is preferable that the server 30 stores the page for receiving the print setting input of the printing images in a correlated manner with the identification information of the printer. With this configuration, when the mobile terminal network transceiver 210 of the mobile terminal 20 transmits a screen request containing the identification information to the server 30, it is possible to acquire a print setting screen in accordance with the kind of the printer for use in printing the printing images and perform print settings in accordance with the kind of the printer.
Although the invention has been described by way of the exemplary embodiments, the technical scope of the invention is not limited to the scope described in the exemplary embodiments. Those skilled in the art will recognize that various modifications or improvements can be made to the details of the exemplary embodiments. It is obvious from the definition of the appended claims that the embodiments with such modifications or improvements also belong to the technical scope of the invention.
