Hi there! I see you’re experiencing printing issues with the HP Smart app on your Android device. Could you please tell me a bit more about what exactly is happening when you try to print? For example, is the app unable to find your printer, does it give an error message, or does the print job just not start?

Meanwhile, here’s a basic set of steps we can try together to get your printing back on track:

1. Restart Your Devices: Turn off your Android device, printer, and Wi-Fi router. Wait for about 10 seconds, then power them back on. This often clears temporary glitches.

2. Ensure Both Devices Are on the Same Network: Make sure your Android device and the printer are connected to the exact same Wi-Fi network.

3. Check Printer Status in HP Smart App: Open the HP Smart app, tap your printer, and see if it shows as connected with no errors.

4. Use the Diagnose & Fix Feature: In the HP Smart app, select your printer, then choose "Diagnose & Fix" from the menu. The app will check for common issues and guide you through fixes.

5. Re-add Your Printer: If the above doesn’t help, try removing the printer from the app and adding it again, following the prompts.

6. Check IP Address Conflicts: Sometimes printers can get IP conflicts on the network. Restarting the router usually helps, but if issues persist, I can guide you through checking the printer’s IP address.

Once you try these steps, let me know what happened or if any messages appeared—I can then guide you further! Does that sound good so far?
