Abstract:
1. A printing apparatus which prints an image on a printing medium, comprising: a print mechanism that performs printing by discharging ink from a print head which relatively moves on the printing medium in a main scan direction and a sub scan direction which intersects the main scan direction; a print control unit that controls an operation of the print mechanism, wherein, in the print head, a plurality of nozzle columns, obtained in such a way that a plurality of nozzles which discharge the ink are arranged in lines in a predetermined range in the sub scan direction, are formed in lines in the main scan direction for each kind of the ink, wherein the print control unit is configured to enable printing to be performed on one side surface of the printing medium by using a first nozzle use setting configured such that, in a first nozzle column of the plurality of nozzle columns, a first nozzle group, which is formed on an upper stream side opposite to a downstream side on which the printing medium moves with regard to the print head, is used as a use range in the predetermined range, and, in a second nozzle column which is different from the first nozzle column, a second nozzle group, which is formed on the downstream side rather than the first nozzle group, is used as the use range, a second nozzle use setting configured such that an entire of a third nozzle column, which is different from the first nozzle column and the second nozzle column, is used as the use range, and a third nozzle use setting configured such that, in the second nozzle column, a third nozzle group, which is formed on the upper stream side rather than the second nozzle group, is used as the use range, and, in the first nozzle column, a fourth nozzle group, which is formed on the downstream side rather than the first nozzle group is used as the use range in order of the first nozzle use setting, the second nozzle use setting, and the third nozzle use setting.
