    • 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.
    • 提供一种用于热敏打印机的热敏打印机和控制方法。 热敏打印机包括打印头和进纸机构,用于基于预定的打印速度控制因素以受控的打印速度传送打印介质经过打印头。 操作包括基于打印速度控制因素确定打印介质的打印速度; 确定打印速度的变化(如果有的话); 确定打印速度的变化是否超过预定的阈值; 以及如果确定所述打印速度的变化已经超过所述阈值,则控制所述供纸机构来限制所述打印速度的变化。 当确定打印速度的变化已经超过阈值时,打印速度的改变减少至少一个预定时间。
