駆動外部コントロール端子付印字装置。 It has a built-in print signal input discrimination circuit, power supply drive signal generation circuit, and power line opening/closing circuit, and the power supply circuit on the printing device side is activated by inputting the print signal from the computer and a constant voltage that is the power source for operating the above circuit. Even if there is no printing signal input, the printing signal input determination circuit determines whether or not to perform the printing operation, and if the printing operation is performed, the printing device is automatically driven by generating a power drive signal and closing the power supply line. Printing device with power-driven external control terminal.
