Abstract
A printing apparatus which avoids the occurrence of banding due to errors of sheet feeding. The apparatus includes a print head with a nozzle array including a plurality of nozzles, a main scan driving unit, a print head driving unit that drives nozzles selected from the array, a sub-scan driving unit that drives the print medium in the sub-scanning direction and a control unit. The control unit controls the main scan driving unit, the sub-scan driving unit and the print head driving unit and also carries out printing on the print medium with the print head. The control procedure of the control unit causes each of the nozzles which are not used in the process of constant pitch sub-scan printing or overlap printing, to create a dot adjoining two dots, where banding is often observed.
