摘要： Disclosed is a recording system in which an operation performed on the side of a printer unit in order to change over recording density is delayed while a recording operation is in progress. When a recording density changeover command is received during a recording operation, the density changeover is performed after the recording operation ends. A control unit which controls the printer unit is informed of the fact that the measures for changing over the recording density have been completed on the printer unit side.

摘要： A light quantity control device suitable for use in a laser beam printer includes a beam generator, a monitor for monitoring the quantity of light of a beam generated by the beam generator, and a controller. The controller controls the light quantity of the beam generated by the beam generator in response to the output of the monitor. The controller includes a digital value output circuit and a light quantity control circuit. The digital value output circuit outputs a digital value representing the quantity of light of the beam, and the light quantity control circuit controls the quantity of light in response to the digital value. The digital value output circuit varies the timing of output of the digital value in accordance with the output of the monitor.
