Abstract
Detecting a print density for the thermal paper based on the outputs of the first and second mark sensors, and adjusting print densities of the first and second thermal heads according to the detection results.
Claims13
A thermal printer comprising:
- thermal paper, which has a thermosensitive layer on one side or both sides, and is fed in a predetermined direction;
- a first thermal head which prints one side of the thermal paper;
- a second thermal head which prints the other side of the thermal paper;
- a control section which selectively prints one side and the other side of the thermal paper with the first and second thermal heads;
- a first mark sensor which detects a mark printed on one side of the thermal paper;
- a second mark sensor which detects a mark printed on the other side of the thermal paper;
- a determination section which determines whether the thermal paper is double-side thermal paper printable on both sides or one-side thermal paper printable on only one side, according to the detection results of the first and second mark sensors;
- a detection section which detects a print density for the thermal paper according to the outputs of the first and second mark sensors;
- and
- an adjustment section which adjusts print densities of the first and second thermal heads, according to the detection results of the detection section.
