Abstract
A laser printer which uses a laser-diode is a peripheral device for a host machine which processes information. The laser printer is a slave of the host machine such that the laser printer forms an image on a paper only as the host machine commands. The laser printer includes a cassette for automatic paper feeding. The laser printer receives data and commands to print the data in a specified format on a paper of a size selected by the host machine. Furthermore, the laser printer includes a manual feeding unit to feed paper to an image forming position. The manual feeding unit includes a sensor for detecting when a paper sheet is inserted into the manual feeding unit. When the sensor detects the paper sheet, the laser printer forms the image on the paper sheet fed by the manual feeding unit in spite of the command from the host machine.
