Abstract

PURPOSE:To provide a thermal printer that is capable of recording thermally with enough concentration even in the initial recording cycle and has capability of unifying recording concentration by supplying preheating voltage in a time that is short to the extent that thermal recording can not be made right before supplying thermal recording voltage. CONSTITUTION:A CPU21 introduces preheating signal (c) and gives it to OR gates 25a-25n for a relatively short time of advance operation part in the high level period of heating instruction signal (a) (the period from the rise time of the heating signal (a) to the time to make the heat generating resistor temperature rise to relatively low temperature that can not be thermally recorded) at an interval of a certain period of heating instruction signal (a). All the heat generating resistors 13a-13n generate heat at temperature that can not be thermally recorded regardless of the existence of printing data. If there is a printing data, after the supply of preheating voltage heating voltage is supplied during the signal time of heating instruction only to heat generating resistors to be thermally recorded only for a period that is enough for thermal recording.
