Abstract
Images are printed up to the edges of printing paper while preventing ink droplets from depositing on the platen. According to the present invention, an area R for ejecting image-forming ink droplets is specified for a region lying beyond the edges of a printing paper P. The pixels of an external upper edge portion Rfp, extending beyond the upper edge Pf, and the pixels of an internal upper edge portion Rfq, disposed downstream of the external upper edge portion Rfp, are recorded solely by the nozzles disposed opposite the downstream slot of the platen. When dots are recorded, blank spaces are prevented from forming in the edge portions of the printing paper, and ink droplets are prevented from depositing on the platen when the printing paper P deviates from its intended position.
