Hi @Chuck4251,

Welcome to HP Support Community.  

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

If you're experiencing issues with your HP ENVY Photo 7855 All-In-One Printer where it requires a restart to function properly, there are several steps you can take to troubleshoot and potentially resolve the problem.

• Update Firmware/Drivers: Ensure that your printer's firmware and drivers are up-to-date. Visit the official HP website, locate your printer model, and download the latest firmware and drivers for your operating system.
• Check Wireless Connection: Ensure that your printer is connected to the same Wi-Fi network as your phone. A stable and reliable connection is crucial for proper communication between devices.
• Printer Software: Make sure that you have the appropriate HP printer software installed on your phone. Sometimes, using the official HP mobile app can improve the communication between your phone and the printer.
• Restart Router: If the issue persists, try restarting your router. Sometimes, network-related issues can be resolved by power-cycling the router.
• Printer Troubleshooter: Most printers come with built-in troubleshooting tools. Use the printer's control panel or the HP Smart app on your phone to run diagnostic tests or troubleshoot connectivity issues.
• Check for Firmware Updates on the Printer: Some printers allow you to check for firmware updates directly from their control panel. Check if your HP ENVY Photo 7855 has this feature and update the firmware if available.
• Static IP Address: Assign a static IP address to your printer instead of relying on dynamic IP assignment. This can help ensure a stable connection between your devices.
• Reset Network Settings on Printer: In the printer's menu, look for an option to reset or restart the network settings. This might help if there are any network configuration issues.
• Firewall/Antivirus Settings: Check if your firewall or antivirus software is blocking communication between your phone and the printer. Adjust settings if necessary.

I hope this helps. 
 

Take care and have a good day.
