Abstract
The invention has an object to provide an advantageous technology that minimizes banding that may appear on an image printed using a print head having a nozzle row (22) to obtain printed images with a better image quality. A print operation includes discharging ink on a printing medium through an active nozzle row (23) and at least one nozzle (21) not continuous from at least one end of the active nozzle row (23). The active nozzle row (23) is re-selected so that an amount of shift of the active nozzle row (23) from one end of the nozzle row (22) is changed every time when the active nozzle row (23) discharges ink a predetermined number of times.
