To connect your HP printer to Wi-Fi during setup, start by turning on the printer and ensuring it’s in setup mode. Use the printer’s control panel to access the network or wireless settings, and select your Wi-Fi network. Enter the Wi-Fi password when prompted. Alternatively, download the HP Smart app from 123.hp.com/setup to simplify the process. The app guides you through connecting your printer to Wi-Fi and completing the setup. Ensure your printer and computer or smartphone are on the same network. Once connected, you can start printing wirelessly with ease.
