ABSTRACT:
A control system for controlling a laser beam printer in which a light-sensitive drum surface is scanned on a line base with a laser beam modulated in accordance with data to be printed. The width of scanning lines is broadened so that the adjacent scanning lines are partially superposed each other at those portions where both of the adjacent lines are to be irradiated with the laser light beam, while at those portions where at least one of the adjacent lines are not to be irradiated, the scanning line is reduced in width.
