Abstract
A thermal transfer printer has been described that includes a print head integrity tester. The tester measures a resistance of each thermal element of the print head to determine if an element is defective. In one embodiment, the resistance is measured by monitoring a current through the element and comparing to a reference. The printer can also include a power strobe adjustment that automatically adjusts the power applied to the print head elements as the thermal elements age.
