Claims

[Scope of Claim for Utility Model Registration] A motor drive control circuit that controls the rotation of a stepping motor that feeds paper via a motor driver circuit; and a motor drive control circuit that controls the motor drive by detecting input from a paper feed key. A control system consisting of a paper feed key detection circuit that sends a signal to the circuit, and a paper end detection circuit that detects the end of stored recording paper using a signal from a detector and sends a signal to the motor drive control circuit. In a printer console equipped with a microprinter, the paper end detection circuit is provided with a function of emitting a trigger signal when the detector detects the leading edge of the recording paper, and is activated upon receiving the trigger signal; a timer circuit that sends a signal to the motor drive control circuit for a predetermined period of time; and a paper end detection circuit that sends a trigger signal to the timer circuit by detecting the leading edge of the recording paper or detects the end of the stored recording paper. 1. A printer console comprising: an online/offline determination circuit that detects and determines whether to send a signal to the motor drive control circuit.
