Abstract:
1. A data processor which generates binary data used for printing in a plurality of pixel regions of a printing medium by a plurality of scans of a printing head respectively comprising: converting means which converts multiple data corresponding to each of the pixel regions into a first binary data corresponding to m×n areas (m and n indicate positive integers, and at least one of m and n is an integer of 2 or larger) forming the pixel region; and generating means which generates a second binary data used in each of the plurality of scans, by use of the first binary data corresponding to a plurality of m×n areas obtained by said converting means and a mask pattern in which print permission areas and print non-permission areas are arranged for each of a plurality of scans respectively, wherein the mask pattern includes two print permission parts each of which corresponds to (an integral multiple of m)×(an integral multiple of n) areas, and the two print permission parts are arranged at a distance of m or n areas from each other.
