Abstract
The present invention is a thermal printhead which includes a substrate portion, a resistive material configured to form a heating element and a thermal barrier island positioned between the resistive material and the substrate portion. The thermal barrier island is defined between the heating element and the substrate portion to reduce the heat flow between the heating element and the substrate portion.
