Abstract
An inkjet printer includes nozzle arrays and a controller. Each of the nozzle arrays includes nozzles arranged in a row along a nozzle array direction. The nozzle arrays are arranged in parallel with each other in a direction perpendicular to the nozzle array direction. The controller is configured to perform such control that in a case where the nozzle arrays include a first nozzle array including a non-ejection nozzle, a defect in a printed image due to the non-ejection nozzle is interpolated by using ejection of an ink by a first nozzle and at least one second nozzle in a second nozzle array different from the first nozzle array among the nozzle arrays, the first nozzle being at a position corresponding to a pixel onto which the non-ejection nozzle is intended to eject an ink, the at least one second nozzle being adjacent to the first nozzle.
