Serial Interface

The printer supports Serial Port as a factory configuration or as a field upgrade kit.
Do not use RS-232 cable adapter dongles for data terminal equipment (DTE) and data communication equipment (DCE) with this printer. Some dongles can interfere with the operation of USB Host port devices at printer power-up.
The printer uses a Null Modem (cross-over) cable for DTE communications. The required cable must have a nine-pin D-type (DB-9P) male connector on one end which plugs into the mating (DB-9S) serial port located on the back of the printer. The other end of this signal interface cable connects to a serial port on the host computer. For pin-out information, refer to Interface Connector Wiring Diagram.
The serial port communication settings between the printer and host (typically a PC) must match for reliable communication. The Bits per second (or Baud rate) and Flow control are the most common settings that get changed.
Serial communications between the printer and the host computer can be set by:
  • ZPL programming
  • Resetting the printer to its default printer configuration.
