Thermal Paper

Thermal paper is a type of paper that can change color when heat is applied to it. This property is used in restaurants in the US and in many other places to print receipts and other documents.

Thermal paper is coated with a layer of chemicals that react to heat. When the paper is passed over a heated print head, the chemicals in the coating heat up and change color. This allows the print head to create an image on the paper without the need for ink.

In restaurants, thermal paper is often used to print receipts for customers. The paper is fed into a printer, and the printer prints the receipt by heating the print head as it moves across the paper. The heat from the print head causes the chemicals in the coating to react, and the receipt is printed on the paper.

Thermal paper is convenient because it does not require ink or toner, and it can be printed on demand. However, it is important to handle thermal paper carefully, as the chemicals in the coating can be affected by exposure to light, heat, and moisture. This can cause the printed image to fade or disappear over time.

If you are using thermal paper in a restaurant or other business, it is a good idea to store the paper in a cool, dry place away from direct sunlight. This will help to ensure that the printed image remains clear and legible for as long as possible.
