ABSTRACT:
A dot forming element array is driven during each main scan to enable successive formation in the main scanning direction of sets of N dots formed substantially along a straight line in a sub-scanning direction at intermittent timing which enables the dot forming element array conducting a scan in the main scanning direction to form a prescribed number of sets of N dots and thereafter disables it from forming dots for (s-1) dot positions (s being an integer greater than 1). An adjustment for shifting the recording positions of the sets of N of dots in the main scanning direction by an integral multiple of the dot pitch w from a prescribed basic position is effected in at least some main scans to enable servicing of multiple dot positions in a desired recording region on the recording medium.
