The mobile terminal network transceiver  210  of the mobile terminal  20  sends the received thumbnails to the input reception unit  200  of the mobile terminal  20 . 
     The input reception unit  200  of the mobile terminal  20  displays the sent thumbnails (S 230 ). For example, when the input to designate the thumbnail “Idle A” is received in Step S 220 , the input reception unit  200  of the mobile terminal  20  displays the page shown in  FIG. 3(   d ) for displaying the thumbnail acquired from the server  30  (S 230 ). 
     The input reception unit  200  of the mobile terminal  20  acquires the identification information stored in the identification information storage  250  and displays the page for receiving a print setting input of the printing images (S 235 ). For example, when the input reception unit  200  of the mobile terminal  20  is displaying the page shown in  FIG. 3(   d ) and when “Next” is pressed on the page shown in  FIG. 3(   d ), a page shown in  FIG. 3(   e ) for receiving the print setting input of the printing images is displayed (S 235 ). 
     The input reception unit  200  of the mobile terminal  20  displays a page for receiving an input to start printing of the printing images corresponding to the thumbnails. For example, when “Next” is pressed on the page shown in  FIG. 3(   e ), the input reception unit  200  of the mobile terminal  20  displays a page shown in  FIG. 3(   f ) for receiving the input to start printing of the printing pages corresponding to the thumbnails. 
     The input reception unit  200  of the mobile terminal  20  receives an input to designate the printing images to be acquired from the server  30  (S 240 ). For example, when “Start Printing” is pressed on the page shown in  FIG. 3(   t , the input reception unit  200  of the mobile terminal  20  acquires the printing images corresponding to the thumbnails from the server  30  and receives the input to designate the printing images to be acquired from the server  30  (S 240 ). Then, the input reception unit  200  of the mobile terminal  20  sends a notification that it has received the input to designate the printing images to be acquired from the server  30  to the mobile terminal local area transceiver  220  of the mobile terminal  20 . 
     The mobile terminal local area transceiver  220  of the mobile terminal  20  transmits the identification information request to the printer local area transceiver  420  of the printer  40  (S 245 ). Then, the printer local area transceiver  420  of the printer  40  transmits the identification information stored in the identification information storage  450  to the mobile terminal local area transceiver  220  of the mobile terminal  20  as a response to the identification information request (S 410 ). The mobile terminal local area transceiver  220  of the mobile terminal  20  sends the received identification information to the input reception unit  200  of the mobile terminal  20 . The input reception unit  200  of the mobile terminal  20  stores the sent identification information in the identification information storage  250  of the mobile terminal  20  and sends a notification that it has received in Step S 240  the input to designate the printing images and information that specifies the designated printing images to the mobile terminal network transceiver  210  of the mobile terminal  20 . The information specifying the printing images may be a file name, for example. 
     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  (S 250 ). 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  (S 330 ). 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  (S 255 ). 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  (S 420 ). 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 (S 430 ). 
     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  (S 260 ). The input reception unit  200  of the mobile-terminal  20  displays that the printer  40  has received the printing images (S 265 ). Specifically, a page shown in  FIG. 3(   g ) for displaying that the printer  40  has received the printing images is displayed (s 265 ). 
     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 S 330  in a correlated manner with the user information received in Step S 250  (S 340 ). 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 S 205  and S 400 ), these steps may be omitted. As an example, subsequent to Step S 200 , 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  (S 210 ). As another example, subsequent to Step S 200 , 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  (S 210 ). 
     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.
