Abstract
An ink jet printer in which a plurality of nozzles includes a failed nozzle that fails to discharge an ink droplet, a primary vicinal nozzle that forms a dot in an adjacent pixel which is adjacent in a direction intersecting a scanning direction to a dot-missing pixel which is caused by the failed nozzle and is continuous in the scanning direction, and a secondary vicinal nozzle that forms a dot in a secondary adjacent pixel which is adjacent to the adjacent pixel on the opposite side of the adjacent pixel from the dot-missing pixel, and a dot formation unit forms a dot by displacing the position of a dot formed by an ink droplet from the primary vicinal nozzle in the scanning direction and the position of a dot formed by an ink droplet from the secondary vicinal nozzle in the scanning direction.
