Printer Not Connecting

[2Clarks]

The setup for my 9120e indicates a "Good" signal strength with my internet. However, the app cannot find the printer. Help, please.

Hi @2Clarks,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP 9120e shows a strong Wi-Fi signal, but the HP Smart app cannot detect the printer. Let’s go through steps to resolve this.

Restart Devices

Turn off your printer, router, and computer/phone.

Wait 30–60 seconds, then power on the router first, printer second, and device last.

This refreshes network connections and often resolves discovery issues.

Check Wi-Fi Network

Ensure your printer and device (computer/phone) are connected to the same Wi-Fi network.

Avoid guest networks or multiple SSIDs with the same name that may confuse the app.

Verify Printer Status

On the printer control panel, check Wireless / Network Settings.

Make sure Wi-Fi is enabled and the printer shows a valid IP address.

Update HP Smart App

Ensure you have the latest version of HP Smart installed on your device.

Sometimes older versions cannot detect newer printer models properly.

Temporarily Disable Firewall / Antivirus

Firewalls or antivirus software can block printer discovery.

Temporarily disable them and try connecting again through HP Smart.

Add Printer Manually

In HP Smart, choose Add Printer → The printer I want isn’t listed → Add using IP Address.

Enter the printer’s IP address from the network settings page.

Reset Network on Printer (if needed)

Go to Settings → Network → Restore Network Defaults.

Reconnect the printer to your Wi-Fi network and retry HP Smart setup.

Test Printing Without HP Smart

Open Control Panel → Devices and Printers → Add a printer and check if Windows detects the printer via IP.

If detected, you can print directly while resolving the app connection issue.

I hope this helps.
