Thermal paper is a special type of paper that is coated with a heat-sensitive material. When exposed to heat, this coating changes color, allowing for the printing of images and text without the need for ink or toner. It is commonly used in devices like receipt printers and fax machines. This paper is often found in everyday items such as cash register receipts and labels. While convenient, thermal paper can be sensitive to light, heat, and moisture, which may affect its longevity. Proper storage is essential to maintain the quality of printed information.
