IMac with macOS M0nterey 12.1 is unable to connect to the HP Laserjet Pro CM1415fnw printer. HELP !!

IMac with macOS Monterey 12.1 is unable to connect wirelessly to the HP Laserjet Pro CM1415fnw printer. HELP !! My IMac cannot find the printer.

HP Easy Start and Easy Admin have been installed but go nowhere to solve connection problem. The printer was working as of Dec 31, 2021. Since then, work no more. I guess it maybe because of the macOS 12.1(?)

Furthermore I cannot find newer firmware (existing ver. 20120629) update for the printer even though a new firmware (20131028) is listed on HP site but I am not able to download for trial on fixing the communication.

Interestingly, computer with Window 10 can communicate to the HP printer and printing document without any issue if the HP software is installed.

Any help to fix the problem is much appreciated. Many thanks to you . STAY SAFE.

@RayNg, Welcome to the HP Support Community! I’m here to help.

I see that you are trying to install the printer on the Mac. Do you get any errors? Let us try these steps:

• Restart the router, the printer, and the Mac
• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
• 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.

• This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK
