— in receipt and label printers, RJ-11 can be used to connect the printer to a cash register or system, providing data transmission over a phone line, although it is used less frequently in modern devices. This connection is useful for older systems or to ensure stable communication in specific working conditions, but it is inferior to more modern interfaces such as USB or Ethernet.
