ABSTRACT:
A thermal printer has with a cover member which swings away from the printer. A thermal line printhead is separated from a platen roller in response to the swinging of the cover member. A paper detector on the cover member swings away from the printer with the cover member. Accordingly, a single sensor detects when paper is loaded in the printer, when the cover is open, and when the thermal line printhead is separated from the platen roller, all of which result in the an interruption or prohibition of printing.
