Abstract
A printer device using thermosensitive paper as a printing medium includes a thermal head for effecting printing on the printing medium, and means for moving the printing medium and the thermal head relative to each other. An electromagnetic plunger and a spring member for urging the thermal head against the printing medium are provided. The plunger serves to control the printing and, in addition, urges the thermal head against the printing medium with a predetermined pressure force, and the spring member is controlled during the relative movement between the thermal head and the printing medium along a print line on the medium, to urge the thermal head against the printing medium with a lower pressure force.
