1. An image formation apparatus comprising:
a communication processor configured to receive print data for pages and print setting information added to the print data from an external apparatus; an image data processor configured to generate page data representing images to be printed on a page basis on the basis of the print data; a print work execution unit configured to form images for one page on one face of each of a recording media on the basis of the page data when the print setting information specifies a one-sided printing, and form images for two pages on both faces of each of the recording media on the basis of the page data when the print setting information specifies a two-sided printing; and a charge information generator configured to generate charge information according to the image formation executed by the print work execution unit, wherein the image data processor is further configured to generates, under a first printing condition where a number of pages of the images represented by the print data is an odd number and the print setting information specifies the two-sided printing, an edited image data for an even number of pages including a blank page with a blank image which does not correspond to the print data as the page data and flag information indicating the presence of the blank page, and
the communication processor is further configured to transmit, under the first printing condition, the charge information and the flag information to an external charge management apparatus, wherein the external apparatus includes:
a print data generator configured to generate the print data on the basis of input data;a setting information generator configured to generate the print setting information; anda transmission unit configured to transmit the print data and the print setting information to the image formation apparatus, wherein the print data generator is further configured to generate, when the two-sided printing is specified and the number of pages of the input data is an odd number, editing image data for an even number of pages including a blank page with a blank image which does not correspond to the input data as the print data, the setting information generator is further configured to generates, when the two-sided printing is specified and the number of pages of the input data is an odd number, information indicating a presence of the blank page in the print data and specifying the two-sided printing as the print setting information, the image data processor is further configured to generate, under a second printing condition where the number of pages of the images represented by the print data is an even number, and the print setting information indicates the presence of the blank page in the print data and specifies the two-sided printing, the page data and flag information indicating the presence of the blank page in the print data, and the communication processor is further configured to transmit, under the second printing condition, the charge information and the flag information to the external charge management apparatus. |
