Cash register paper refers to specialized thermal receipt rolls designed for cash registers, primarily used to record transaction details and provide customers with receipts. It is an "instant information recording carrier" for quickly generating transaction vouchers in transaction scenarios such as retail and catering. Thanks to its special thermal-sensitive coating on the surface, it can instantly display key information like product details and amounts solely through the heat of the printer, without the need for ink or carbon tape throughout the process. This not only simplifies operations but also effectively ensures the traceability of information for each transaction.
