The printing control part 7 prints image data of a plurality of pages by two sets by simultaneously adopting the double-sided printing process, W stapling process and W allocating process, and can carry out a W printing process mode of allocating image data of the first set to the first printing regions of the printing pages in a page sequence, and allocating image data of the second set to the second printing regions of the printing pages in a page sequence reversed from that of the image data of the first set at the time of the W allocating process. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
