Abstract
A printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.
Claims20
A printer, comprising:
- a thermal printhead including resistive heating elements;
- a motor for conveying paper to the thermal printhead;
- a power supply configured to supply power to the thermal printhead and the motor;
- and
- a processor configured to cause the supply of power to the motor to be paused if the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor, wherein
- the power threshold value is based on a number of energized resistive heating elements per a line of print data supplied to the thermal printhead for printing.
A printer, comprising:
- a thermal printhead including a plurality of resistive heating elements in a line;
- a platen roller facing the thermal printhead;
- a motor configured to drive the platen roller and convey paper to the thermal printhead by rotation of the platen roller;
- a power supply configured to supply power to the thermal printhead and the motor;
- and
- a control unit configured to control the supply of power to the resistive heating elements and the motor, the control unit causing the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor, wherein
- the power threshold value is based on a number of energized resistive heating elements per a line of print data supplied to the thermal printhead for printing.
A control method for a printer including a thermal printhead and a motor, the control method comprising:
- cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor, wherein
- the power threshold value is based on a number of energized resistive heating elements per a line of print data supplied to the thermal printhead for printing.
