ABSTRACT:
A reference pattern is printed on one of the printing regions as the printing head moves in one direction, and a comparison pattern, which is to become a pattern identical to the reference pattern, is printed on the other of the printing regions as the printing head moves in both directions. A judging process is provided in which the comparison pattern is compared with the reference pattern so as to judge whether the two patterns are identical or not. The relative positional relation is determined to be proper if the two patters have been judged to be identical.
