Abstract
When an image is to be printed by the so-called multi-scanning method where image data corresponding to one band width is printed by a printhead scanning for a plurality of times, masking is performed on the image data in each of the scanning operation, and an image is printed on the basis of the masked image data. In such manner, pixels printed in each scanning form an image corresponding to one-scanning data (one band width of the data). At the time of printing by multi-scanning, a preliminary pulse is added prior to a driving pulse which drives the printhead so that the density of the image printed by multi-scanning is not decreased. In addition to changing such driving condition of the printhead, the density of the image data outputted to the printhead may be changed.
