Printing up to edges of printing paper without platen soiling

摘要

Images are printed up to the edges of a print medium while preventing ink droplets from depositing on the platen. Ink droplets are ejected without blank space up to the edges of the medium according to print data. The print medium is supported opposite a dot-recording head. Ink droplets are ejected to a first area lying outside of an upper edge of the print medium and to a second area lying outside of a lower edge of the print medium. A length of the second area in a sub-scanning direction is greater than a length of the first area in the sub-scanning direction. In device embodiments, control of such operations is provided by a controller.
