Abstract:
1. A printing system comprising: (A) a head that is furnished with a plurality of nozzles and that ejects ink droplets that correspond to pixel data from each of the nozzles; (B) a carry unit that carries a medium; (C) a memory storing position information that indicates a relationship between a position of a dot to be formed by an ink droplet that is ejected according to the pixel data and a position of a pixel on the medium that corresponds to that pixel data; and (D) a controller that alternately repeats a dot formation operation of causing ejection of the ink droplets from the nozzles which move in a movement direction to form the dots in the movement direction, and a carrying operation of causing the carry unit to carry the medium, to print an image on the medium; wherein, when forming a row of dots lined up in the movement direction with a predetermined number of at least two nozzles by repeating the dot formation operation of forming dots at a predetermined pitch in the movement direction and shifting the positions, in the movement direction, of the dots that are formed in each dot formation operation, the controller
