Abstract

Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.
