Abstract
A color printer for high-quality image recording. The printer comprises printer controller 200 having image memories (video RAM's) and printer engine 300. Memory selector 2005 changes over the image memory for forming image data by color component, and outputs a color designation signal CRCD indicative of a currently-used image memory. The CRCD signal value is '00' to indicate Y image memory 2001; '01', M image memory 2002; '10', C image memory 2003; and '11', K image memory 2004. Thus the CRCD indicates the color of the current image memory. Upon smoothing, VDO signal processor 302 changes over the smoothing logic based on the CRCD signal, accordingly, an appropriate smoothing logic for each color component image data can be applied.
