@Lisa8622, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
If your HP OfficeJet Pro 8710 printer says it's connected to Wi-Fi but shows as "offline" when you try to print, here are some steps to help resolve the issue:

Restart Everything

• Power cycle your printer, computer, and router.
• Unplug the printer and router for 30 seconds, then plug them back in.

Check Printer’s Wireless Connection

• On the printer’s control panel, go to Wireless Settings > Wireless Network Test Report.
• Ensure the printer is connected to the correct network (same as your computer).

Set Printer to Online

• On your computer:
  • Go to Control Panel > Devices and Printers.
  • Right-click your HP 8710 and select “See what’s printing”.
  • In the new window, click Printer > Use Printer Offline to uncheck it.

Reinstall the Printer Driver

• Go to HP official support site and download the latest driver for the HP OfficeJet Pro 8710.
• Uninstall the current printer from your PC and reinstall it using the new driver.

Assign a Static IP Address

• On the printer’s control panel, go to Settings > Network > Wireless > Advanced Settings > IP Settings.
• Set a manual IP address (you can find the current IP under Network Summary and use it as a base).

Use HP Print and Scan Doctor

• Download and run HP Print and Scan Doctor.
• It can automatically detect and fix many connectivity issues.
