PROBLEM TO BE SOLVED: To eliminate degradation in image quality due to discharge abnormality of a nozzle.SOLUTION: A printer executes printing by discharging ink droplets from a plurality of nozzles onto a printing medium. In the case where an abnormal nozzle having abnormality in the discharging ink droplets is included in a plurality of specific nozzles when the printer prints specific raster lines by causing the plurality of specific nozzles included in the plurality of nozzles to share discharging of a plurality of ink droplets for representing the specific raster lines directed in a first direction on the printing medium, the printer increases ink amounts of ink droplets adjacent to a position of an ink droplet to be discharged by the abnormality nozzle in the first direction by nozzles not being the abnormality nozzle out of the plurality of specific nozzles and discharges the ink droplets.SELECTED DRAWING: Figure 3 |
