Thermal Paper Roll
Thermal paper (sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color when exposed to heat. It is used in thermal printers, particularly in inexpensive or lightweight devices such as adding machines, cash registers, and credit card terminals.
The surface of the paper is coated with a solid-state mixture of dye and a suitable matrix; a combination of a fluoran leuco dye for example. When the matrix is heated above its melting point, the dye reacts with the acid, shifts to its colored form, and the changed form is then conserved in a metastable state when the matrix solidifies back quickly enough. The reactant acid in thermal paper is often bisphenol A (BPA).
While an open heat source, such as a flame, can discolor the paper, a fingernail swiped quickly across the paper will often generate enough heat from friction to produce a mark.

Thermal paper is a type of paper that is coated with a special heat-sensitive material. It is commonly used in thermal printers for receipts, labels, and other applications.
Yes, exposure to sunlight, heat, and certain chemicals can cause thermal prints to fade over time. It’s recommended to store thermal paper rolls in a cool, dark place.
