PROBLEM TO BE SOLVED: To accelerate the speed of image data transfer in a continuous paper both-side printer. SOLUTION: In the continuous paper both-side printer, the printing of even-number pages is delayed by several pages than the printing of odd-number pages due to the upper/back side reversing of the continuous paper. In the printer, a printer controller generates odd-number page image data and even-number page image data in the order of the pages, proceeds to a process to generate image data of a next page without executing 180°-rotation processing when the even-number page image data serving as back-surface image data is generated, gives the generated odd-number page image data to an upper-surface image processing device when the upper-surface image processing device requires the surface image data, subjects the generated even-number page image data serving as back-surface image data to the 180°-rotation processing when a back-surface image processing device requires the back-surface image data, and gives the processed image to the back-surface image processing device.
