@AviHarrow, Welcome to HP Support Community. 

 

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

I understand your HP ENVY Photo 7800 series printer is showing as offline and displaying the code B8DA8066. Let's walk through the steps to bring your printer back online.

Restart Devices

  • Turn off your printer and unplug it from the power source.
  • Restart your computer and your Wi-Fi router.
  • Plug the printer back in and power it on.

Check Network Connection

  • Ensure your printer and computer are connected to the same Wi-Fi network.
  • On the printer, check the Wireless icon:
    • Solid blue light = connected.
    • Blinking or off = not connected. Reconnect using the printer’s control panel.

Run HP Smart Diagnose & Fix Tool

  • Download or open the HP Smart app on your Windows 10 PC.
  • Click the wrench icon (bottom left) and select Diagnose & Fix.
  • Follow the on-screen instructions to automatically detect and resolve issues.

Check Printer Status in Windows

  • Go to Control Panel > Devices and Printers.
  • Right-click your printer > See what’s printing.
  • Click Printer in the top menu and ensure "Use Printer Offline" is unchecked.
