Re: Zebra wireless printers not getting an IP

Thank you for clarifying that @cjoseph.

I will leave it off on the SSID and opt to disable MFP on the device itself.

Re: Zebra wireless printers not getting an IP

My original post was removed for some reason. Just wanted to repost.

 

This managed to be resolved by support from Zebra.

Zebra article here.

Zebra printer: QLn420

 

Our setup:

  • Using 802.1x on our wireless and the Zebra is setup to do WPA-PEAP-WPA2-PEAP (as shown in the Zebra config). 
  • User authentication, role, and VLAN all come from ClearPass

Initial behavior:

  • The Zebra printer was able to authenticate without issue. It passed authentication in the ClearPass and it was confirmed that it was receiving the correct user role and VLAN.
  • Once authenticated, the device was not able to get an IP address via DHCP.
  • If a static IP was assigned, it was still unable to communicate.

Solution:

  • Disabling MFP/PMF in the Zebra printer and rebooting it immediately resolved the issues with the printer getting an IP.

Re: Zebra wireless printers not getting an IP

Here are the steps I took in case the link goes down.

 

Just in case the link go does here are steps:

  1. Install the Zebra Setp Utilities You will need to register an account to download.
  2. Connect your printer to your computer. I did it via USB
  3. Open the Zebra Setup Utilities application and select your printer from the list and click on Open Communication with Printer

  4. Type the following into the resulting configuration window. Once done, click Send to Printer. NOTE: ensure the config ends with a carriage return. I.E. cursor should be blinking on a blank line.

  5. Printer will then restart and MFP/PMF should be diabled.

Here are the commands:

! U1 setvar "wlan.pmf" "disabled"
! U1 do "device.reset" ""
