ABSTRACT:
Image data having a predetermined pixel density, and output from a personal computer, is supplied to an image-resolution conversion apparatus connected to a printer having a pixel density different from the above predetermined pixel density. In the image resolution conversion apparatus, the pixel density of the input image data is converted, by a pixel converter, to a pixel density matching that of the printer, according to a conversion ratio set by a pixel-density conversion ratio setter for setting a ratio of pixel-density conversion, from the pixel density of the personal computer to that of the printer. The pixel-density converted image data is then supplied to and printed by the printer.
