Printing method of thermal printer

Abstract

Abstract PURPOSE:To reduce the lateral width of a heat generating resistor, by driving the selected same heat generating resistor of a thermal head plural times while successively shifting the same to a printing region and always printing one dot of printing paper by dividing printing. CONSTITUTION:A printing control part 4 selectively applies a pulse signal to a heat generating resistor corresponding to printing data and drives the same heat generating resistor continuously two times in order to print printing data. When one heat generating operation of heat generating resistors 1a, 1b,...1g was finished, the printing control part 4 operates a head control part 5 to shift a thermal head 3 to an A-direction and applied printing to printing paper 6. By this system, one dot of the printing paper is always printed in a state divided into plural times and, therefore, the lateral size of each heat generating resistor can be made short and a heat generating resistor with low resistance can be prepared without lowering sheet resistance.
