PURPOSE:To provide the titled system by which errors due to variations in operating conditions can be easily corrected without the need to adjust a paper- feeding mechanism part, wherein the printing starting position relative to the end of the paper can be finely adjusted by a group of switches. CONSTITUTION:A controlling part 5 for feeding the paper drives a pulse motor 7 for driving a paper-feeding roller through a motor driver 6. The output from a sensor 2 is read through a receiver 9, and when the end of the paper is detected by the sensor 2, the pulse motor 7 is stopped. Information set through the switch group 13 is read through a switch group receiver 12, and the direction and the amount of movement of the paper is calculated on the basis of the thus set information. A number of pulses correspondig to the movement amount is output to the pulse motor 7 through the motor driver 6, and the paper is moved in a supplying direction or a discharging direction. |
