Hi @Dldaven,
Welcome to The HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand you are getting an error code 30 on an HP OfficeJet Pro 6978 All-In-One Printer, often described as "printer not activated," typically indicates a problem with the printer's communication with your computer.
Here are some steps to troubleshoot and resolve this issue:
Check Printer Connections:
- Ensure the printer is properly connected to your computer via a USB cable or network (Wi-Fi/Ethernet).
- If using a USB connection, try a different USB port on your computer.
- If using a network connection, ensure the printer is connected to the same network as your computer.
Restart Devices:
- Restart both your printer and computer. This can often resolve temporary communication issues.
Update or Reinstall Printer Drivers:
- Visit the HP Support website and download the latest drivers for your HP OfficeJet Pro 6978.
- Uninstall the current printer driver from your computer.
- Reinstall the downloaded driver and follow the installation instructions carefully.
Set the Printer as Default:
- Go to the Control Panel (Windows) or System Preferences (Mac).
- Navigate to the Printers section.
- Right-click on your HP OfficeJet Pro 6978 and select "Set as default printer."
Check Printer Status:
- Ensure the printer is online and not in an error state. You can do this from the printer's control panel or the printer settings on your computer.
Run HP Print and Scan Doctor (Windows):
- Download and run the HP Print and Scan Doctor tool from the HP Support website.
- Follow the on-screen instructions to diagnose and fix any printer issues.
Disable Firewall/Antivirus Temporarily:
- Sometimes, firewall or antivirus software can block printer communication. Temporarily disable them to see if this resolves the issue. Remember to enable them again after testing.
Check for Windows Updates:
- Ensure your operating system is up to date, as updates can include fixes for known issues.
Test Printing:
- Try printing a test page from the printer settings or a simple document from an application like Notepad or TextEdit.
