@AM253, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand your HP Smart Tank 5102 was printing fine from your phone earlier, but has suddenly stopped working even though nothing has changed with your Wi-Fi or phone. Let's walk through a few steps to get things working again:

Restart Devices

• Power off your printer, phone, and Wi-Fi router.
• Wait 30 seconds, then power them back on. This refreshes network connections.

Check Printer Connection

• Make sure your printer is still connected to the same Wi-Fi network as your phone.
• On the printer control panel, go to Settings > Wireless Settings > Wireless Summary to confirm connection status.

Use HP Smart App

• Open the HP Smart app on your phone.
• If the printer is not listed, tap “+” to add it again.
• If it shows as offline, tap the printer icon and check for any alerts or errors.

Re-add Printer in HP Smart

• Remove the printer from the app. HP Smart
• Re-add it by tapping “+” and selecting your printer from the list.
• If it doesn’t show up, tap “Set up a new printer” and follow the prompts.

Check for Firmware Updates

• Open HP Smart app > Tap your printer > Go to Advanced Settings > Printer Updates.
• Install any available updates. Update the firmware on an HP printer | HP® Support

Reset Network Settings (if needed)

If the printer still won’t connect:

• On the printer, go to Settings > Restore Network Settings.
• Reconnect it to Wi-Fi using the HP Smart app.

If none of these steps help, you can try a full reset:

• Uninstall and reinstall the HP Smart app.
• Factory reset the printer: Go to Settings > Restore Settings > Restore All Settings.

I hope this helps. 

Take care and have a good day.
