Driving method of thermal printer |
摘要 |
In a driving method of a thermal printer, in which method heating elements are driven by strobe pulses consisting of preheat pulses and subsequent drive pulses that depend on a gradation level, the preheat pulse width and the frequency of basic clock pulses that are used to generate the strobe pulses are switched linearly with the temperature of a thermal head unit. In particular, based on data of preheat pulse widths and basic clock pulse frequencies for respective experimental head temperatures, preheat pulse widths and basic clock pulse frequencies for the other temperatures are calculated.
