Abstract
A printer includes a thermal head configured to print information on thermal paper, a platen roller configured to press the thermal paper against the thermal head and a paper feed unit configured to convey the thermal paper. The printer further includes a control unit configured to control the paper feed unit to convey a leading edge of the thermal paper to a print waiting position between the thermal head and the platen roller, and also configured to control the paper feed unit to move the leading edge of the thermal paper from the print waiting position to a retracted position upstream the print waiting position.

A printer comprising:
- a thermal head configured to print information on thermal paper;
- a platen roller configured to press the thermal paper against the thermal head;
- a paper feed unit configured to convey the thermal paper;
- and
- a control unit configured to control the paper feed unit to convey a leading edge of the thermal paper to a print waiting position between the thermal head and the platen roller and configured to control the paper feed unit to move the leading edge of the thermal paper from the print waiting position to a retracted position upstream the print waiting position.
A printer comprising:
- a thermal head configured to print information on thermal paper;
- a platen roller configured to press the thermal paper against the thermal head;
- a paper feed unit configured to move a leading edge of the thermal paper;
- and
- a paper sensor configured to detect the leading edge of the thermal paper to determine whether the thermal paper is located at a print waiting position between the thermal head and the platen roller for a predetermined time period.
A method for controlling a printer including a thermal head for printing information on thermal paper, a platen roller for pressing the thermal paper against the thermal head and a paper feed unit configured to convey the thermal paper, the method comprising:
- conveying a leading edge of the thermal paper to a print waiting position between the thermal head and the platen roller;
- and
- moving the leading edge of the thermal paper from the print waiting position to a retracted position upstream the print waiting position.
