A receipt printer is a specialized device used to print receipts for transactions, commonly found in retail stores, restaurants, and other businesses. These printers typically use thermal printing technology, which allows them to produce high-quality prints quickly and quietly without the need for ink or toner. Receipt printers connect to point-of-sale (POS) systems, enabling businesses to provide customers with a printed record of their purchases. They come in various sizes and styles, including portable models for mobile transactions. Many receipt printers also support features like barcode printing and connectivity options such as USB, Bluetooth, or Wi-Fi.
