What is a Thermal Printhead
A thermal printhead is a key device used for the printing part of thermal type image output equipment.
The thermal printing method is used for label prints and receipts at retail stores, logistics, food barcode labels, ID cards, air and railway tickets, X-ray films, and food date printing.
A thermal printhead has multiple heating elements (heaters) lined up in a row on a heat storage layer (glaze). It is a device that prints by transferring heat generated when electric current flows through the heater to the printing media (thermal paper or ink ribbon).
