Method and device for switching on and off the power supply of a printer

摘要

According to a method for switching on and off the power supply of a printer (3), this is carried out as a function of the data and control signals sent to this printer, in that a receiving part of the printer (3) is simulated. In this arrangement, the simulation is undertaken in a device (2) which continuously monitors, in a control unit, the data and control signals communicated from a computer (1) to the device (2).
