ABSTRACT:
An ink jet printing apparatus carries out printing using a connecting head formed of a plurality of chips connected together, each having an array of nozzles through which ink is ejected. Potential white stripes, which are attributed to connecting portions in each chip, can be suppressed. Each nozzle array is provided with connecting portion nozzles and non-connecting portion nozzles. The connecting portion nozzles in one of the nozzle arrays overlaps the corresponding non-connecting portion nozzles in another nozzle array in a direction in which the nozzle arrays are arranged. Ejection of ink droplets from the non-connecting portion nozzles is controlled in accordance with printing conditions.
