Hi @KI-Photogirl , 

Welcome to HP Support Community.  

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

If your HP OfficeJet Pro 6978 All-In-One Printer is unable to scan to your computer and you are receiving a "no computer found" message, there are several steps you can take to troubleshoot and resolve the issue. Here are some suggestions:

Check Connection:

• Ensure that your printer and computer are connected to the same network.
• Confirm that the printer is turned on and connected to the network.

Update Drivers:

• Make sure that you have the latest printer drivers installed on your Mac. Visit the official HP website to download and install the latest drivers compatible with macOS 12.0 Monterey.

HP Easy Scan:

• Use the HP Easy Scan application on your Mac to scan documents. This app is designed to work seamlessly with HP printers. Make sure it is installed, and try scanning through it.

Restart Devices:

• Restart both your printer and your computer. This can often resolve communication issues.

Firewall/Antivirus Settings:

• Check if your firewall or antivirus software is blocking communication between the printer and the computer. Temporarily disable these software tools and attempt to scan again.

Check Network Settings:

• Confirm that your printer and computer are on the same network. If you have a dual-band router, make sure both devices are connected to the same frequency (2.4 GHz or 5 GHz).

HP Smart App:

• Consider using the HP Smart app, which is available for macOS. This app allows you to manage your printer and perform scanning functions. Install the app, connect your printer, and try scanning through it.

Reinstall Software:

• Uninstall the printer software on your Mac and reinstall it. Follow the official HP instructions for uninstalling and reinstalling the printer software.

Check System Preferences:

• Open System Preferences on your Mac, go to "Printers & Scanners," select your printer, and ensure that it is set as the default printer.

I hope this helps. 

Take care and have a good day.
