Abstract
This invention allows images to be printed up to the edges of printing paper while preventing ink droplets from depositing on the platen. Ink droplets Ip are ejected from a print headand printing is started when printing paper P is fed in the sub-scanning direction by upstream paper feed rollersand, and the front edge Pf reaches a position above a downstream slot. Since printing is started when the front edge Pf of printing paper P has reached a position behind nozzle No., images can be printed without forming blank spaces up to the front edge Pf of the printing paper P by causing the nozzles to eject ink droplets Ip irrespective of whether the nozzles are above the printing paper. When images are formed in the vicinity of the front edge Pf of printing paper P, the paper is repeatedly fed in small increments in the sub-scanning direction, and printing is carried out. Adopting this arrangement makes it possible to print images on the front-edge portion of the printing paper when the paper is above the downstream slot
