PROBLEM TO BE SOLVED: To eliminate the difference of image density between multiscan printing and single scan printing. SOLUTION: At the time of multiscan printing, a nozzle control section 70 masks the image data at each scanning time to interpolate the data being printed at each scanning time. Furthermore, at the time of multiscan printing, a pulse control circuit 72 adds a preliminary delivery pulse to the driving pulse for head 49 thus preventing the image density from lowering. |
