Abstract

A tape printer that prevents shifting of a printed dot due to a reverse rotation caused by the DC motor stop when power supply to a DC motor is resumed. When the power supply to the DC motor is suspended, the DC motor often rotates in a reverse direction immediately before rotation of the motor stops. The amount of reverse rotation is detected by an encoder. This amount is compensated immediately after the power supply to the DC motor is resumed. After the amount of forward rotation identical to the amount of reverse rotation amount is detected, printing is resumed by the printing head.
