Patent ID: 8018621

Claim:
A data generating apparatus for generating binary data used for performing printing on a printing medium by using a printing head in which a plurality of nozzles are arranged, said apparatus comprising: a setting part for setting a printing mode, in which a plurality of movements of the printing head are performed and the printing medium is conveyed by a conveying amount smaller than an arranging width of the plurality of nozzles of the printing head between each of the plurality of movements, to perform printing on an area corresponding to the conveying amount; a selection part for selecting a binarization pattern having a number of pixels corresponding to a divisor of a number of pixels that corresponds to the conveying amount in the printing mode set by said setting part, from a plurality of binarization patterns that differ in a number of pixels in a conveying direction of the printing medium from each other; and a generation part for generating binary data corresponding to the area by using a binarization pattern selected by said selection part.
