The Zebra Ethernet upgrade kit is suitable for Zebra label printers in the version ZD410, ZD420C, ZD420D and ZD420T. These label printers do not have an Ethernet port in the standard version, but with the upgrade kit you can easily provide your Zebra label writer with a 10/100MB Ethernet network connection. This way you can easily and quickly set up a printer network. After mounting, you can neatly finish the Ethernet port with the supplied cover plates.
