Hi @Barry138 ,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If your HP OfficeJet Pro 7740 Wide Format All-In-One Printer is having trouble finding your computer for wireless scanning after you upgraded to macOS 12.0 Monterey, there are  steps you can take to troubleshoot and resolve the issue:

Check Network Connection:

• Ensure that both your printer and your computer are connected to the same Wi-Fi network.
• Check if your Wi-Fi network is working properly.

Verify Printer Connection:

• Make sure that your HP OfficeJet Pro 7740 is connected to the Wi-Fi network. You can usually do this through the printer's control panel or settings menu.

Update Printer Drivers:

• Visit the official HP website to check for updated printer drivers that are compatible with macOS 12.0 Monterey.
• Download and install the latest drivers if available.

Restart Devices:

• Power off both your printer and your computer.
• Wait for a few minutes and then turn them back on.
• Check if the issue persists.

Reinstall Printer Software:

• Uninstall the existing printer software on your Mac.
• Download and install the latest HP printer software compatible with macOS 12.0 Monterey from the official HP website.

Check Firewall Settings:

• Ensure that your firewall settings are not blocking the communication between your printer and computer.
• Check if any security software or firewall on your Mac is preventing the connection.

Reset Printing System:

• Go to "System Preferences" on your Mac.
• Select "Printers & Scanners."
• Right-click on the printer and choose "Reset printing system."
• Re-add your printer and check if the issue is resolved.

I hope this helps. 

Take care and have a good day.-

Gaya, I tried it all. Firewalls enable HP Scan 3 as well, so it's still not working. Regards, Barry

I should also mention that I'm running Mac OS Sonoma, Version 14.1.2

To be more usefull than HP Support, HP has decided to stop supporting this function : it has no link with Mac OS Sonoma. On my network, it stop working in the same time with Sonoma and Catalina. It's because of a september firmware update.

Thanks Alan. I eventually got the same advice from HP, with an offer of a discount on a new one that is compatible. I think a 6 year life span for a printer/scanner is short!
