Welcome to the HP support community.

I understand that you want to connect the printer to the new WiFI connection, I am glad to assist you.

Restore network settings to default settings

• Press and hold (the Information button) for 3 seconds, and then release the button. All control panel buttons will light up. 
• Press and hold (the Wireless button) and (the Cancel button). The printer restarts and, depending on your printer model, the Status light pulses purple or (the Wireless button) starts blinking blue. This indicates that the printer is in wireless setup mode. You can now set up a wireless connection between the printer and your device.

You can connect the printer to a new connection using the HP Smart app
