    • The invention discloses a thermal head controller for controlling a thermal head for use in a printer, the thermal head serving to form an image with at least one color on print paper. A thermal head controller according to one aspect of the invention includes signal generating means (101) for generating a control pulse signal (HSTR) serving as a reference signal according to which the energizing of the printing heater is controlled; and preheating control means (110) for controlling the energizing of the preheating heater by means of counting the control pulse signal. In this construction, the energization start time of the preheating heater is controlled by means of counting the control pulse signal which is also used to control the energization of the printing heater. This makes it possible to control the energization start time of the preheating heater without resulting in an increase in complexity of the circuit. Furthermore, by setting the control pulse signal to have a proper pattern, it is possible to control both the energization of the preheating heater and the energization of the printing heater in a highly effective fashion thereby increasing the printing speed using a simple configuration.
    • 本发明公开了一种用于控制打印机中使用的热敏头的热敏头控制器,该热敏头用于在打印纸上形成至少一种颜色的图像。 根据本发明的一个方面的热打印头控制器包括:信号发生装置(101),用于产生用作参考信号的控制脉冲信号(HSTR),根据该参考信号来控制打印加热器的激励; 以及预热控制装置(110),用于通过对控制脉冲信号进行计数来控制预热加热器的通电。 在这种结构中,通过对控制脉冲信号进行计数来控制预热加热器的通电开始时间,该控制脉冲信号也用于控制打印加热器的通电。 这使得可以控制预热加热器的通电开始时间,而不会导致电路的复杂性增加。 此外,通过将控制脉冲信号设置为具有适当的图案,可以以高效的方式控制预热加热器的通电和打印加热器的通电,从而使用简单的配置来提高打印速度。
