Abstract
A thermal printer for forming an image on a sheet includes a thermal head having a plurality of linearly arranged thermal elements. A total number of thermal elements to be energized to form the line image is determined. A difference between the total thermal elements to be energized to form the line image, and previous number of the thermal elements that were energized to form a previous line image is calculated. The thermal elements are then driven for a period of time which is a function of the difference between the total number and the previous number that was calculated.
