Abstract
A printer may be used to print on print media, such as labels, where the print media, as fed through the print, spans substantially less than the full width of the printhead and platen. This may result in uneven print pressure across the print media during the print process. The uneven print pressure, in turn, may result in an uneven print density on the print media, which causes poor print quality. A system and method is employed with identifies the uneven print pressure, and compensates for the uneven print pressure to ensure consistent print density and good print quality. Along segments of the printhead which apply a below average pressure to the print media, the printhead is configured to apply a proportionately higher density of an appropriate contrast-inducing element, such as ink or heat. Along segments of the printhead which apply an above average pressure to the print media, the printhead is configured to apply a proportionately lower density of an appropriate contrast-inducing element, such as ink or heat.
