Abstract
In a control system for a laser printer, an AND gate is connected to a circuit system extending from a DC controller circuit to a driving circuit for a laser diode. A mask signal of 'L' level is output from the port OPM of the DC controller circuit to the AND gate when a print stop key on an operation panel is switched on. Thereby, the print operation of a print mechanism is immediately stopped. This efficient method of interrupting printing prevents toner from being wasted on a printing error and allows immediate interruption when a printing error is discovered.
