Title: Printing control method of laser beam printer
Inventor: ORIHARA KATSUHISA
IPC: B41J2/44
Filed: 1983-08-26
Abstract: PURPOSE:To minimize the lowering in an effective printing speed at the time of intermittent printing, by neglecting time difference from irradiation of laser beam to transfer at the time of intermittent printing. CONSTITUTION:Data transfer is enabled after T2+T3 (wherein T2 is a mechanical operation time required in starting printing and T3 is a mechanical operation time required in finishing printing) has passed since printing data was interrupted. An effective printing speed at the time of intermitted printing comes to T4/(T2+T3+T4) (wherein T4 is a data transmitting time when printing data is continuously transmitted) of the speed at the time of continuous printing. Because of T2<=T1 (wherein T1 is time difference from laser irradiation to transfer), the lowering of the effective printing speed at the time of intermittent printing can be minimized.
