Apparatus, system, and method for frictionally reacting thermal paper

摘要

A frictional printing device, system and method prints on thermal paper using heat generated by frictional contact. A frictional actuator motivates a frictional heating element to frictionally contact the thermal paper. The thermal paper is chemically treated to react to heat by changing color. Heat is generated by frictional contact of the frictional heating element against the thermal paper. The frictional contact may be provided through repetitive movement of the frictional heating element. An image is formed by selectively positioned frictional contact between the frictional heating element and the thermal paper.
