Factory reset M29W printer

[Jl2030]

I got a new internet service provider and my network has changed And my printer doesn’t know where everyone went. How can I reset it and start over?

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• 1.) Are the printer and Mac connected to the same network?
• 2.) Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual-band has different SSIDs for 2.4G and 5G networks.
• 3.) What is the distance between the router and the printer?

While you respond to that, let's try these steps: Perform a ping test to check the connectivity

1. Click Applications > Utilities > Terminal.
2. type ping "IP address" and press enter

Wait until 10 pings have been performed and then press ctrl c on the keyboard and hit return. 
The results will appear. Share the ping test results.
 

The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold option-click the WiFi icon and then use shift-command-5 to take the screenshot. Press the space bar when the icon turns into a camera. Share the ping test results and the screenshot with us.

Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.  Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems. 

Hope this helps! Keep me posted for further assistance.
