Abstract
In multi-nozzle ink jet printing for divisional-printing or color-printing information on a single paper with ink of a same color or of different colors ejected from a plurality of nozzles which are mounted on a carriage, a unique method is provided for the prevention of unregistered printing of an image due to positional deviation between the ink issuing from the respective nozzles with respect to a direction of movement of the carriage. A difference in position between ink drops from the respective nozzles with respect to the direction of carriage movement is detected so as to determine the timings for starting printing with the ink from the respective nozzles based on the detected difference.
