1. A printing apparatus comprising:
a medium transport member for transporting a medium in a medium transporting direction; a first nozzle group for a first color in which a plurality of nozzles for ejecting a first color ink are arranged in a width direction of the medium; a second nozzle group for the first color in which the plurality of nozzles for ejecting the first color ink are arranged in the width direction of the medium and which is disposed to be offset from the first nozzle group for the first color in the transporting direction, wherein seeing in the medium transporting direction, the first nozzle group for the first color and the second nozzle group for the first color have a first overlapping area; a first nozzle group for a second color in which a plurality of nozzles for ejecting a second color ink are arranged in the width direction of the medium; a second nozzle group for the second color in which the plurality of nozzles for ejecting the second color ink are arranged in the width direction of the medium and which is disposed to be offset from the first nozzle group for the second color in the transporting direction, wherein seeing in the medium transporting direction, the first nozzle group for the second color and the second nozzle group for the second color have a second overlapping area; a first nozzle group for a third color in which a plurality of nozzles for ejecting a third color ink are arranged in the width direction of the medium; a second nozzle group for the third color in which the plurality of nozzles for ejecting the third color ink are arranged in the width direction of the medium and which is disposed to be offset from the first nozzle group for the third color in the transporting direction, wherein seeing in the medium transporting direction, the first nozzle group for the third color and the second nozzle group for the third color have a third overlapping area; a first nozzle group for a fourth color in which a plurality of nozzles for ejecting a fourth color ink are arranged in the width direction of the medium; a second nozzle group for the fourth color in which the plurality of nozzles for ejecting the fourth color ink are arranged in the width direction of the medium and which is disposed to be offset from the first nozzle group for the fourth color in the transporting direction, wherein seeing in the medium transporting direction, the first nozzle group for the fourth color and the second nozzle group for the fourth color have a fourth overlapping area, wherein seeing in the medium transporting direction, the first overlapping area is located at a position different from the position of each of the second overlapping area, the third overlapping area and the fourth overlapping area, and wherein the second nozzle group of each color are disposed adjacent to the first nozzle group of the corresponding color in the transport direction. |
