Connecting to Your Network through the Printer’s Ethernet Port

To use a wired print server (Ethernet) connection, you may need to configure the printer to communicate with your Local Area Network (LAN).
For printers purchased in the EMEA region after August 1, 2025, you must configure a Protected Mode password and front panel password for the printer before you can perform wired or wireless setup. For additional information, go to zebra.com/asr or refer to the Zebra Link-OS PrintSecure Printer Administration Guide.
For other printers with Protected Mode enabled, depending on the configuration, you may need to enter the Protected Mode password to change certain settings on the printer. For more information, refer to the Zebra Link-OS PrintSecure Printer Administration Guide.
For additional information about Zebra print servers, refer to the ZebraNet Wired and Wireless Print Server User Guide. To download the latest version of this guide, go to zebra.com/manuals.
  1. After you install the drivers (see Installing the Drivers), connect the printer to an Ethernet cable that is connected to your network.
    Connect the Ethernet cable
  2. Plug the A/C power cord into the A/C power connector on the back of the printer.
    Plug in the power cord

  5. Turn on (

    ) the printer.
    Turn on the printer
    The printer attempts to communicate with your network. If it is successful, it fills in your LAN's gateway and subnet values and gets an IP address.
    If you need to power cycle the printer, allow it to fully boot up first. Then after turning it off, wait 30 seconds before turning it back on. Power cycling the printer too quickly can cause issues.
    If you did not install the drivers first, see What to Do If You Forget to Install Printer Drivers First.
  6. On the Home screen, touch the Printer Info tab. Check the display to see if an IP address was assigned to the printer.
    If the printer’s IP address is...
    Then...
    0.0.0.0
    or
    000.000.000.000
    The NETWORK light is off or displays steady red. (See Indicator Lights for more information.)
    1. Check the Ethernet connector on the back of the printer. If no light is on or blinking, the Ethernet connection is not active. Check that both ends of the cord are plugged in correctly and that the network port that you are plugging into is active. When this issue is resolved, the printer should connect automatically.
    2. If necessary, configure the following printer settings to set a static IP address and then reset the network. Contact your network administrator for the proper values for your network.
    any other value
    The connection was successful. The NETWORK light displays steady green or yellow, depending on the network. (See Indicator Lights for more information.)
  7. Reset the network (see Connection > Networks > Reset Network) to allow changes to the network settings to take effect.
