1. Check Printer Status

• Restart Printer: Turn off the printer, wait for 30 seconds, and then turn it back on.
• Check Connection: Ensure the printer is properly connected to the WiFi network. You can print a Network Configuration Page from the printer settings to verify the connection.
• Set as Default Printer: Ensure the HP OfficeJet Pro 6978 is set as the default printer on your Windows 11 computer. Go to Settings > Devices > Printers & scanners and click on the HP OfficeJet Pro 6978, then select Set as default.

2. Restart Print Spooler Service
