Abstract
When a position deviation of more than 1/2 pitch of ejection port pitch is generated by a difference in thermal expansion between ejection ports of a low temperature line head and ejection ports of high temperature line head, a dummy data is inserted in part of ejection data arrangement, so that ejection data inherent in the arrangement is shifted by one ejection port unit to be assigned to other ejection ports This reduces position deviation between dots formed by individual heads according to the data to less than 1/2 pitch.
