How Are Receipts Printed?
In today’s digital world, where most transactions are done electronically, receipts still play a crucial role in keeping track of purchases and providing proof of payment. But have you ever wondered how receipts are printed? Let’s take a closer look at the process.
Receipts are usually printed using thermal printers. These printers use heat to create an image on a special type of paper that reacts to heat. The paper is coated with a chemical that changes color when heated, producing the text and images on the receipt. Thermal printers are widely used in retail stores, restaurants, and other businesses because they are fast, quiet, and require no ink or toner.
The process starts when a transaction is completed. The point-of-sale (POS) system sends the transaction data to the thermal printer. The printer receives this data and converts it into a printable format. It then heats up tiny dots on the print head to create the desired text and images on the thermal paper.
