ABSTRACT:
A printer includes a ribbon supply end, a ribbon retrieving end, and a ribbon. The two ends of the ribbon are installed on the ribbon supply end and the ribbon retrieving end respectively. The printer further includes a print head, a print medium fixture, a driving module for driving the ribbon from the ribbon supply end to the ribbon retrieving end, a moving shaft for moving from a first position of the ribbon between the print head and the ribbon supply end so as to elongate the ribbon between the print head and the ribbon supply end before the print head transfers dye on the ribbon onto the print medium and when the print head and the print medium fixture clamp the print medium, and a control module for controlling the printer according to whether the moving shaft can be moved from the first position to a second position.
