Patent ID: 7746489

Claim:
An image forming apparatus comprising: a scaling circuit subjecting image data of each of a plurality of images to a scaling process, the plurality of images being selected to be printed on one sheet of printing paper; a microcomputer using the scaled image data of each of the images to prepare printing image data for printing the images on the printing paper; and a print mechanism printing the images on the printing paper according to the printing image data, wherein if the image data of the plurality of images includes image data that is improper for being subjected to the scaling process and printed on the printing paper, the microcomputer prepares the printing image data in such a manner that a region in which an image corresponding to the improper image data is to be printed is left blank and an image whose image data has been subjected to the scaling process is arranged at its corresponding region; and wherein the print mechanism does not perform the process of printing on the printing paper if the total number of images whose image data is improper is equal to the maximum number of the images that can be printed on the printing paper.
