Abstract: A printer system includes a printer on which color and monochromatic print cartridges are mounted, and a personal computer to output bit map data to the printer. The kinds of these ink cartridges are memorized as status information within a RAM so that the personal computer can detect a cartridge mounted position based on the status information. In the case that the color and/or monochromatic print cartridge is mounted incorrect, the personal computer detects an amount of a difference from a normal mount position to cause print data to shift depending upon the difference, thus creating bit map data.
