What component in a thermal printer is responsible for applying heat to the thermal paper in order to create an image?
Pickup Roller
Transfer Roller
Heating Element
Duplexing assembly
The heating element-often referred to as the thermal printhead-generates precise, localized heat that triggers the color-changing coating on thermal paper, forming text or graphics. The pickup roller merely feeds paper, the transfer roller is used in laser printing to move toner, and a duplexing assembly flips pages for two-sided printing; none of those parts create heat on thermal paper.
