Abstract
In a printing apparatus capable of printing the same pixel by a plurality of print elements, a print speed is increased, and further, a partial frequency of use of each of the print elements is reduced, so as to prolong the lifetime of the print head. In view of this, dithering is used as a pseudo-halftone representing method, and further, a distribution pattern for use in creating image data to be distributed to each of the plurality of print elements is switched.
