Abstract
A method is provided for detecting the type of print media provided to a thermal printer. A printer has a heat source disposed adjacent a temperature sensor to transfer heat upon activation across a portion of an introduced print media to the temperature sensor and a controller to receive a signal from the temperature sensor and to obtain a temperature signature generally identifying attributes of the introduced print media and to adjust print head settings in response to the identified attributes. The printer may further comprise a sensor to detect access to a print media storage compartment and to initiate examination of the heat transfer properties of the introduced print media upon detecting that the print storage compartment has been accessed.
