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 head 28 and printing is started when printing paper P is fed in the sub-scanning direction by upstream paper feed rollers 25a and 25b, and the front edge Pf reaches a position above a downstream slot 26r. Since printing is started when the front edge Pf of printing paper P has reached a position behind nozzle No. 1, 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.

Abstract: When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ?T lower than the head temperature Tfinish.
