Abstract
In an ink jet printing device wherein when a number of n nozzles are sequentially arranged in the direction of transport of recording paper and spaced apart from each other by a distance corresponding to m characters or ink dots so that when ink dots discharged from each nozzle are arranged in one column on the recording paper in the direction of transport thereof, the adjacent ink dots have a very small spacing, but they are nearly in contact with each other, a modulo-m address counter is stepped so as to store data in a memory while a modulo-n address counter is stepped to read out data. Thus positional deviations between nozzles may be compensated.
