Hi @Pranit2611,

Welcome to the HP Support Community. 

I'd be glad to help you! 

Make sure, your printer and your device are on the same network as 2.4GHZ only. 

Is it a private (Home network) or a public Wi-Fi connection? Wi-Fi direct? Or Hotspot?
What device are you using the printer with a Windows computer, Mac, Android, or iPhone?

Restore an HP Smart Tank printer to factory defaults and set up the printer using the HP Smart app.

From the left side of the printer, lift the ink access door.

On the printer control panel, press the Information button for three seconds.

All buttons on the control panel light up.

Press the Information button and the Cancel button until 00 displays and the Wi-Fi button blinks.

Lower the ink access door.

Wait for 30 seconds.

Press the Power button or disconnect the power cable to turn off the printer.

Turn on the printer, and then wait until the Wi-Fi button blinks and Wi-Fi icon on the printer display cycles.

The printer enters into Wireless Setup Mode.

Open the HP Smart app, add the printer, and then follow the prompts to complete the printer setup.

Update the firmware. Click here

Hope this helps! Keep me posted for further assistance
