Abstract
A thermal printer and control method for a thermal printer is provided. The thermal printer includes a print head and a paper feed mechanism for conveying a print medium past the print head at a controlled print speed based on predetermined print speed control factors. Operations include determining the print speed of the print medium based on the print speed control factors; determining a change, if any, in the print speed; determining if the change in print speed exceeds a predetermined threshold value; and controlling the paper feed mechanism to limit the change in the print speed if the change in the print speed is determined to have exceeded the threshold value. The change of the print speed is decreased for at least one predetermined time when the change in the print speed is determined to have exceeded the threshold value.
