HP DeskJet 4120e - Connecting to Win10 Desktop PC

[jjs1973]

I am having problems with setting this device up.

The initial setup was completed via my mobile phone, and that all appears to be fine. I can print from the handheld device.

I can not for the life of me get my Win10 device to find the device though via the Smart HP app. The printer is connected WiFi to my network, PC is connected via LAN. We are on the same IP subnet. 

I've unisntalled and reinstalled. Rebooted. Disconnected from network, and reconnected. 

When did printer setup become so difficult??

Hi @jjs1973,

Welcome to the HP Support Community. 

Let me ask you few questions in order to assist you better.

Did you make any changes to your printer?

Are you able to connect other devices to the same wireless network?

Have you replaced the router recently?

Are there any wireless interferences?

Are you connecting the printer to a 2.4Ghz network or 5Ghz network?

Excellent description and a great diagnosis. It is greatly appreciated.

Let's continue with the troubleshooting now.

Try the steps recommended below.

Restart the computer, printer, and router to resolve any error states present during the printer setup.

   NOTE:

The following steps temporarily disconnect network and Internet connections, and require restarting your computer. Complete any tasks or downloads in progress before continuing.

Disconnect the power cord from the router.

Turn off the printer.

Close all running programs on your computer, including the HP software installation window, then shut down the computer.

Reconnect the power cord to the router, then wait for the Internet activity light to display a normal connected status.

Turn on the printer.

Turn on the computer.

Try installing the HP driver and software again.

Use Wi-Fi Protected Setup (WPS), HP Smart, or temporarily connect a USB cable to establish a wireless connection between your printer and network.

Connect the printer with WPS

Use WPS to connect the printer to your wireless network.

Locate the WPS button on your router, but do not press it yet.

If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

Reset the printer network settings. Press and hold the Wireless and Cancel buttons until the Power light blinks. Wait until the Wireless light blinks.

Any network settings on the printer are now reset. Your printer remains in setup mode for 2 hours.

NOTE: 

For HP Tango printers, press and hold the Wireless button on the back of the printer for 5 seconds. The Edge lighting flashes blue to indicate the printer is in wireless setup mode.

On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

NOTE: 

The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that timeframe, attempt these steps again.

Once the printer is connected, the blue Wireless light stops blinking and remains on.

Lastly, if nothing works restore the printer network settings to default and connect the printer back to the network again.

To restore network settings to default settings

● Press the Wireless button and the Cancel button from the printer control panel at the same time, and then hold them for three seconds
