The term “57mm printing paper” refers to paper that is 57mm wide and is frequently used with thermal printers, including card printers, portable handheld printers, and cash registers. It’s common practice to print receipts, tickets, and labels on paper of this size. Typically, thermal sensitive paper is used for the paper, which has a coating of a special substance that reacts to heat and enables the printer to produce sharp, clear images and text. Additionally, it comes in a variety of roll lengths. It is widely used in fields that require small, portable printers, such as retail, hospitality, healthcare, and others.
