Abstract
A thermal printer early printhead failure prediction system detects possible printhead and/or printing clement failure in response to the sensed resistance of the printhead or an individual element thereof. A microprocessor of the printer monitors the resistive trends of the printing elements. A warning is generated when a characteristic of the resistive trend exceeds a predetermined boundary.
