<p>A printer aiming at preventing the banding which has been caused by an accumulated error of paper feeding or by a difference in a drying level of ink due to a time difference in the raster forming thereby to invite a deterioration in the image quality. The printer comprises: a printing head (28) having a nozzle array composed of a plurality of nozzles; a main scan driver (3) for the printing head (28); a printing head driver (5) for driving the nozzles selected from the nozzle array; a sub-scan driver (4) for carrying a printing medium (8) in a sub-scanning direction; and a driver control unit (2) for controlling the main scan driver (3), the sub-scan driver (4) and the printing head driver (5) to print on the printing medium (8) by the printing head (28). At a time of a fixed pitch sub-scanning print or an overlap print, dots are printed adjacent to each other between two dots, where banding is likely to occur under the control of the driver control unit (2) by the nozzles which are not employed in the particular printing mode.</p> |
