Abstract
A printer with a printhead pressure adjusting mechanism including a thermal head, a platen drum, an adjusting mechanism, a detection device [e.g., switch(es)] and a control unit. The thermal head transfers ink of an ink ribbon onto recording paper by heat generation. The platen drum sandwiches the ink ribbon and the recording paper under pressure together with the thermal head. The adjusting mechanism adjusts the pressure being applied to the thermal head when pressing the thermal head. The detection device detects the size of the recording paper. The control unit controls the adjusting mechanism in order to adjust the pressure being applied to the thermal head in accordance with the detected size of the recording paper.
