Abstract
A printer includes: a printing head including a plurality of resistors; a controller configured to drive the printing head by dividing the printing head into at least two areas; and an assisting circuit that assists power supply, wherein the controller controls to overlap time periods for driving two different areas, and the assisting circuit supplies an electric current to the printing head together with an electric current supplied from the power source during the overlapping period.
Claims7
A printer comprising:
- a printing head including a plurality of resistors;
- a controller configured to drive the printing head by dividing the printing head into at least two areas;
- and
- an assisting circuit that assists power supply,
- wherein the controller controls to overlap time periods for driving two different areas, and
