<p>PURPOSE:To prevent the mixture of noises due to the application of the power supply of a connecting device against an output equipment by instructing the initialization to the output side via an instruction means at application of the power supply of the connecting device and then initiarizing the output equipment. CONSTITUTION:The centronics input parts IN0-IN3 are provided together with the centronics output part OUT, a connection means which secures the connec tion between one of parts IN0-IN3 and the part OUT, and an instruction means which instructs the initialization of the equipment connected to the part OUT. Then the control is carried out so that the instruction means performs its instructions at application of a power supply. In other words, a signal is outputted to the centronics output to urge the initialization. Thus an output equipment is initialized with application of the power supply of the connecting device. Then it is possible to prevent the printing of the illicit data which are outputted in an unstable state caused by the application of the power supply.</p> |
