ABSTRACT:
When a malfunction nozzle occurs in a joint portion of print elements in a print head, the print head is controlled to minimize image impairments caused by the malfunction nozzle. This prevents an increase in cost of the print head and increases the printing speed while at the same time realizing a high quality of printed image. For the control of the overlapping nozzles in the adjoining print chips, a desired control mode is selectively set from among a plurality of control modes, the control modes having different nozzles removed from use.
