Abstract

Methods of improving print quality are disclosed herein. An example method of improving print quality may be embodied by a method of temperature compensation for a thermal printhead having a plurality of heating elements, including identifying, for the heating element corresponding to the column of the pixel, when a number of pulses delivered to the heating element in a predetermined window prior to a line of the pixel is outside of a defined range and responsive to determining that the number of pulses is outside the defined range, and prior to printing the pixel, adjusting the pulse sequence to be delivered to the heating element corresponding to the column of the pixel to print the pixel at a line of the pixel following the predetermined window.
