Thank you for posting your query, I will be glad to help you. 
If your HP Smart Tank 790 series printer is showing as offline and displaying an error code, here are some steps to help you get back up and running:

Check Printer Connection

Ensure your printer is properly connected to your network:

• If using Wi-Fi, make sure the printer and your computer/mobile device are on the same network.
• If using USB, ensure the cable is securely connected and not damaged.

You can also try restarting your printer, router, and computer.

Use HP Smart App – Diagnose & Fix Tool

HP provides a built-in tool in the HP Smart app that can automatically detect and fix many issues:

1. Open or install the HP Smart app.
2. Go to “Printer Settings” > “Advanced Settings” > “Diagnose & Fix”.
3. Follow the on-screen instructions.
