To connect your HP Smart printer to Wi-Fi, the easiest method is to use the **HP Smart app** on your phone or computer. Here are the key steps:

1. **Ensure your printer is powered on** and ready. If the Wi-Fi light is not blinking, press and hold the Wi-Fi and Cancel buttons on the printer until the light blinks to enter wireless setup mode.
2. Make sure your phone or computer is connected to the Wi-Fi network you want the printer to join.
3. **Download and open the HP Smart app** (available for iOS, Android, and Windows).
4. In the app, sign in or create an HP account if needed.
5. Use the app to **add your printer**—it should detect your printer automatically or let you add it manually.
6. Follow the prompts to select your Wi-Fi network and enter the password.
7. Once connected, the app will confirm and the printer’s Wi-Fi light will stop blinking, showing it’s successfully connected to the network[1][3][4].

Alternative methods include:

– Using the printer’s built-in touchscreen or control panel to run a **Wireless Setup Wizard**, selecting your network, and entering the password directly on the printer[4].
– Using **WPS (Wi-Fi Protected Setup)** if your router supports it: press the WPS button on your router, then on your printer within 2 minutes, and they will connect automatically without needing a password[4].
– Connecting the printer to your computer with a USB cable, then using HP software to transfer your wireless network details and configure the printer for Wi-Fi[4].

If your printer doesn’t connect immediately, you can put it into wireless setup mode by holding the wireless and cancel buttons until the light blinks, which allows the printer to be discovered by the app and reconnect to Wi-Fi[2][3].

This approach works for most HP smart printers and DeskJet models. Using the HP Smart app is generally the simplest and most flexible way to set up Wi-Fi connectivity.
