Thermal printing is a technology that uses heat to transfer ink onto paper. It works by applying heat to a special thermal paper, which changes color when heated. This method is commonly used in receipts, labels, and barcodes because it produces clear and durable prints quickly. There are two main types of thermal printing: direct thermal and thermal transfer. In direct thermal printing, the printer uses heat-sensitive paper, while in thermal transfer printing, a ribbon is heated to transfer ink onto the paper. Both methods are efficient and widely used in various industries, including retail and logistics.
