Thermal transfer paper is a type of paper that is heat-sensitive and reacts when interacted with a heated pin. Thermal Transfer labels offer greater durability, provide more protection against environmental conditions, and yields a longer shelf life. Thermal transfer printing is one of the most popular methods used for producing high quality, free format, random, on demand printed images. The advantages of low equipment cost, low maintenance costs, high image quality, quiet printer operation, and small size make this technology well suited for printing bar code symbols.
