Thermal paper is a special type of paper that, when in contact with heat, changes its colour to black or, sometimes, to blue or red. The terms 'heat-sensitive paper' and 'audit roll' are often used as synonyms for thermal paper.

There are two primary types of thermal paper: Direct Thermal Paper and Thermal Transfer Paper. Direct thermal paper has a heat-sensitive coating on one side that changes color when exposed to heat, making it ideal for printing receipts and labels quickly and inexpensively.
