Thermal printer rolls are rolls of special paper used in thermal printers to produce printed output. Unlike traditional printers that use ink or toner to create images and text on paper, thermal printers use heat to produce images on specially coated paper.Thermal paper typically consists of several layers, including a base layer made of paper or plastic, a thermal coating layer, and sometimes a protective layer. The thermal coating contains a combination of chemicals, including dyes and developers, that react when exposed to heat.When a thermal printer heats specific areas of the thermal paper, the coating reacts and changes color, creating the desired text, images, or graphics. This process eliminates the need for ink or toner cartridges, making thermal printing more cost-effective and efficient.Thermal printer rolls come in various sizes and specifications to accommodate different types of thermal printers and printing requirements. They are commonly used in applications such as point-of-sale systems, credit card terminals, receipt printers and label printers
