Title: Color printing apparatus

Abstract: A color printing apparatus is provided for realizing highly attractive print images and high speed color printing with a relatively simple position control. The color printing apparatus comprises a printer unit for printing a color print image composed of a dot matrix on a printing medium, a feeder unit for feeding the printing medium, a reciprocal moving mechanism for reciprocally moving the printer unit in directions orthogonal to a direction in which the printing medium is fed, and a controller for instructing the printer unit to perform printing in a plurality of colors to each dot of the color print image so as to selectively conduct uni-directional printing and/or bi-directional printing in the reciprocal movements of the printer unit. The controller instructs the printer unit to conduct the uni-directional printing for a high contrast color with respect to a background color of the printing medium within the plurality of colors, and to conduct the bi-directional printing for the remaining colors.
