摘要： A thermal head avoids a drop in print quality caused by adhesion of printing chaff. A thermal head 39 that presses against thermal paper that moves from one side to the other side and prints by melting dye contained in the thermal paper has a glazed layer 150 that is formed in an area on one part of a ceramic substrate 43 and stores in-flowing heat, and a heating resistor 140 that is located offset to one side from the center of the glazed layer 150, selectively heats the thermal paper S pressed in contact therewith, and melts a dye material contained in the thermal paper. A smooth surface P against which the thermal paper S heated by the heating resistor 140 slides is formed to the other side of the glazed layer 150 from the heating resistor 140.

摘要： A thermal printer 1 and control method for controlling print speed to prevent variation in printing pitch due to frequent slight changes in the print speed following a significant change in print speed. The print speed, which is the speed at which the print medium i.e., paper is conveyed when printing, is controlled based on known print speed control factors. The thermal printer comprises a paper feed mechanism for conveying the print medium at a controlled print speed passed a thermal print head, a print speed control unit 9 for controlling the print speed of the paper feed mechanism based on the print speed control factors, a print speed change acquisition unit 3 for determining the change in the print speed over a predetermined time, and a comparison unit 7 for determining if the change in print speed exceeds a predetermined threshold value. The print speed control unit 9 limits change in the print speed based on the print speed control factors for a predetermined time after the comparison unit 7 determines that the change in print speed exceeds the threshold value.

摘要： High print quality from a thermal printer is maintained while the print speed is decreasing without producing white streaks or uneven print density by controlling the hysteresis coefficient of the thermal print head 35 based on the energizing history of the thermal print head 35 and print speed control factors used for determining print speed, which is the speed at which the paper is advanced while printing. The thermal printer, comprises a hysteresis coefficient setting unit 2 for setting a hysteresis coefficient for the print head based on the energizing history of the thermal print head 35; an energizing time calculation unit 3 for calculating the energizing time during which drive signals are to be applied to the thermal print head 35 for printing based upon the hysteresis coefficient set by the hysteresis coefficient setting unit; a printing control device 4 for generating the drive signals to be applied to the print head in response to the energizing time calculated by the energizing time calculation unit 3; a print speed determination unit 5 for determining the change in the print speed and when the print speed is decreasing; and a coefficient changing unit 6 for changing the hysteresis coefficient when a change in print speed occurs causing the print speed to decrease. Preferably the coefficient changing unit changes the hysteresis coefficient to a value greater than the hysteresis coefficient value used immediately before deceleration.

摘要： 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.
