Abstract

A color printer has multiple printing heads that print dots in different colors, one dot line at a time. Each line is divided into at least two parts. For each printing head, the printer has an image data memory that stores data for at least two dot lines. When a printing head prints one dot line, data for each part of the dot line are taken from an independently-selected line in the image data memory. The image lines are selected so as to correct positional skew between different printing heads.
