HP M28W factory reset needed, WIFI cannot find printer

[FLOwiththaFLO]

HI, upon moving homes the printer that previously worked does not connect to the wifi or the computer anymore Mac OS. even after resetting the printer settings on the computer. Printer is no longer visible through USB either, could someone help me. I found similar cases were a factory reset was the solution , but it seems this protocol is only communicated through PM.

I reviewed your post and I understand that the printer is not connecting to your Mac computer wirelessly.

Don’t worry, I assure you I will try my best to get this sorted.

I'd like to know the following to isolate the issue further-

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?

4.) Is there an antivirus software installed on your Mac?

5.) Could you perform a ping test using the Mac Network Utility and let me know the results? Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display.

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. 

Look forward to hearing from you and have a great day!

Take care.

Cheers!
