Abstract

PURPOSE:To make the density of prints uniform, in a printer having a printing magnet, by providing a controlling circuit for changing a period for magnetizing the printing magnet to change the magnetizing period in accordance with the dot density of the print pattern. CONSTITUTION:In the printer wherein a prescribed pattern is printed on a paper 2 by magnetizing for a prescribed period a printing magnet in a printing head 4, a circuit for controlling a magnetizing period of the printing magnet that consists of a counter 8, a magnetizing pulse generating part 7, etc. is provided. The dot density of dots constituting letters or figures is calculated by the counter 8 to send a signal corresponding to the dot density to the magnetizing pulse generating part 7 for generating magnetizing pulses that magnetizes the printing magnet. Thus the magnetizing period of the printing magnet is controlled, and when the dot density is high, the light dot is printed on the paper 2 with a small energy, and the print density is made uniform.
