Abstract
A primary matrix pattern such as 5 .times. 7 matrix structure and an auxiliary matrix pattern such as 4 .times. 6 matrix structure are combined with each other in an ink jet system printer in such a manner that auxiliary dots contributing to the auxiliary matrix pattern are shifted in both column and row directions by a half dot position with respect to the primary matrix pattern. These auxiliary dots function to increase dot density along oblique lines in the dot matrix pattern.
