Abstract
A printing device includes a first nozzle column in which nozzles discharging liquid to a medium are arranged in a line in a predetermined direction, a second nozzle column in which nozzles discharging liquid to the medium are arranged in the predetermined direction, in which the first and second nozzle columns are arranged in a line in an intersecting direction with respect to the predetermined direction, a control portion which causes the first nozzle column and the second nozzle column to discharge the liquid to the medium while moving the first and second nozzle columns and the medium relatively to each other in a moving direction, in which the control portion forms a certain correction pattern composed of a first pattern formed by the first nozzle column and positioned on one side in the intersecting direction with respect to the moving direction and a second pattern formed by the second nozzle column and positioned on the other side in the intersecting direction with respect to the moving direction in parallel with the first pattern, and the correction pattern forms another correction pattern in which the distance between the second side end of the first pattern and the first side end of the second pattern in the intersecting direction with respect to the moving direction is different from that in the certain correction pattern.
