To add an HP printer to your Wi-Fi network, the most common and straightforward method is to use the printer’s built-in **Wireless Setup Wizard** from its control panel (if it has a display screen). You navigate to Setup > Network Settings > Wireless Setup Wizard, select your Wi-Fi network, and enter the password directly on the printer. Upon success, you should see a connection confirmation and a solid Wi-Fi light[1].

If your printer or router supports **WPS (WiFi Protected Setup)**, you can press the WPS button on your router, then press the WPS button on your printer within 2 minutes. This automatically connects the printer to Wi-Fi without entering a password[1].

Alternatively, you can use the **HP Smart App** on your smartphone or computer:

1. Turn on the printer and ensure it is ready for wireless setup (Wi-Fi light blinking).
2. Open the HP Smart App, and add a new printer.
3. Select your Wi-Fi network and enter the password.
4. Follow prompts on the app and printer (such as pressing the Information button).
5. The printer connects to the Wi-Fi and the Wi-Fi light stops blinking[2][3].

For printers without displays, you can also connect them to a computer temporarily via USB, use the HP software to set up Wi-Fi on the printer, then disconnect the USB cable[1].

If you need to reset the wireless settings to reconnect to a new Wi-Fi network, you can usually press and hold the Wireless and Cancel buttons until the power light blinks. This puts the printer into setup mode so you can start fresh with the wireless connection setup[4].

In summary, the key methods to add your HP printer to Wi-Fi are:

– **Wireless Setup Wizard** on the printer screen (most models with displays)
– **WPS button connection** (if supported)
– **HP Smart App setup** on phone or computer
– **USB setup** for printers without display
– **Reset wireless settings** if reconnecting to a new network

These steps cover most HP printers made in recent years[1][2][3][4].
