Abstract
To provide a technique for largely preventing conspicuous banding from appearing in printed images, a print head is provided with three nozzle rows in which a plurality of nozzles are arrayed in a sub-scanning direction, the nozzle rows being spaced apart in a main scanning direction. In two nozzle rows among the three nozzle rows, the positions of the nozzles in the sub-scanning direction are mutually the same, and in one nozzle row among the three nozzle rows, the positions of the nozzles the sub-scanning direction lie between nozzles of the two nozzle rows in the sub-scanning direction. The three nozzle rows can eject ink of the same hue.
