ABSTRACT:
A color printing apparatus includes a printing head which prints different color segments of an ink ribbon on a sheet, and an image data memory storing a plurality of color image data corresponding to a color image. The color segment opposed to the printing head is identified. The color image data is read out and serves for judging whether or not the identified color segment is to be subjected to printing. With the judgment that the identified color segment is to be subjected to printing, the image data memory transmits a signal actuating the printing head. With the judgment that the identified color segment is not to be subjected to printing, the ink ribbon is driven to feed the next color segment so as to oppose to the printing head.
