How do I find out the MAC address on a HP LaserJet M111a printer?

[Happyneo]

How do I find out the MAC address on a HP LaserJet M111a printer? Maybe print a networking info page? I tried reading the manual and printing a configuration report but it does not contain MAC address. I need this info to add to a router allowlist. Can't look it up on the router and there is no information on the printer's label. Please help.

Page 4 of the reference manual shows how to get a network report.

Press and hold the Wireless button for more than 10
seconds (but less than 20 seconds

To avoid registering your printer on the system, you might consider printing directly to the printer.

Watch the reset video or perform the steps. After resetting, you generally have 2 hours to complete the setup. Decide if you want to connect the printer to the router or to print directly to the printer and bypass the router.

Many HP and other OEM printers have problems with the router when the router has two bands and both bands have the same name (SSID). Log into the modem and rename one of the bands. Alternately, contact your ISP and have them rename a band.

Or simply use Wi-Fi direct (but read note below about Instant Ink).

If English is not your native language or if you wish to get additional information not covered below, then use the HP and Microsoft support assistants. The latest HPSA supports 36 languages and can be downloaded here. Microsoft's AI assistant is in the latest Windows 10 and 11 releases and there are instructions here on how to enable the AI. Microsoft's AI assistant (Copilot) has a microphone button and supports natural language processing.

Do not call any phone numbers shown in any of the videos or revealed by a Bing or Google search. You may need to reset your printer.

Disconnecting the USB cable may still leave the printer in the wired or Wi-Fi mode. Connecting an ethernet cable may still leave the printer in Wi-Fi mode. The Wi-Fi reset is used to put Wi-Fi printers into setup mode. Some resets are simple and others require a video to understand. Factory resets cannot be revealed in this forum. To do a factory reset of your printer, you must contact HP.

Wi-Fi reset instructions and videos (if any) are shown below. Generally you have 2 hours to connect your printer after performing the Wi-Fi reset. Note that a reset video may show a slightly different model than yours. Do not call any phone numbers revealed in any video or site.

Microsoft's Copilot may have more recent videos.

1. Turn off the printer.
2. Press and hold the Wireless button and the Cancel button simultaneously.
3. Keep holding both buttons for about 10 seconds, or until the power light starts blinking.
4. Release the buttons.

Wi-Fi connection

Ideally, your Wi-Fi printer should connect to the modem or router. If your network has multiple boosters / repeaters, it is possible the printer may connect randomly to any of the units. The router needs to provide the same IP address on every connection. This rarely happens with random connects. An alternate Wi-Fi connection is Wi-Fi direct. Your laptop or smartphone prints directly to the printer and does not go through the router. Note that if you signed up for instant ink or internet printing your printer must also be online through the router. Do not call any phone number revealed in any video or site.

Wi-Fi Direct can be used to avoid configuring the router. Watch this: 2:50 in this video
Wi-Fi Direct is explained on page 19 of the User Manual, this Wi-Fi setup avoids configuring the router.
A simple connection to the router can be done by using the WPS pushbutton method. This is explained on page 6 in this User Manual.

Let me know if a problem

This printer does not have Wi-Fi, just a network jack in the back of it. So, this solution does not work for me, unfortunately.

Indeed,

The printer have no wireless capabilities but offers a USB connection only, therefore any such networking information is not applicable for the printer model:
