Patent ID: 7393070

Claim:
A printing device that prints a predetermined image onto a printing medium using a printing head that includes a plurality of nozzles each capable of dot formation to the printing medium, the printing device comprising: an image data acquisition unit that acquires image data corresponding to a plurality of pixels of the image; a printing data generation unit that generates, based on the acquired image data, printing data including information about dot formation details based on the pixels for each of the nozzles; a nozzle information storage unit that stores information about any of the nozzles having dot formation details that are different from predetermined dot formation details; and a printing unit that prints, based on the printing data, the image onto the printing medium using the printing head, wherein by referring to the nozzle information storage unit for storage details therein, the printing data generation unit generates the printing data providing a lower resolution for the image to be printed by at least one of: the nozzle of different dot formation details; and any neighboring nozzles; as compared with a resolution of the image data acquired by the image data acquisition unit corresponding to the nozzle used for printing; and wherein with respect to values of the pixels of the image data corresponding to the nozzle of different dot formation details and the any neighboring nozzles, the printing data generation unit selects, for every line of the image, the nozzle of different dot formation details and the any other neighboring nozzles for exclusion from use for printing the image of the image data, and generates the printing data based on the values of the pixels of the image data corresponding to the selected nozzles.
