To add a printer to Wi-Fi, first ensure the printer is turned on and near your Wi-Fi router. Then use the printer’s control panel to access the wireless setup wizard: select **Setup** or **Network** > **Wireless Setup Wizard**. Choose your Wi-Fi network name from the list, enter the Wi-Fi password, and confirm the connection is established (often indicated by a Wi-Fi icon on the printer screen)[1][2][4][5].

If your router supports WPS (Wi-Fi Protected Setup), you can press the WPS button on the router, then use the printer’s control panel to select **Wi-Fi Setup** > **Push Button Setup (WPS)** to connect automatically without entering a password[1][2].

After the printer connects to Wi-Fi, on your computer or device, go to **Settings** > **Bluetooth & devices** > **Printers & scanners** and select **Add a printer** or **Add device**. Choose your wireless printer from the list to complete installation[3].

Key steps summarized:
– Turn on printer and place it near the Wi-Fi router.
– Use the printer’s wireless setup wizard to select your network and enter password.
– Or use WPS button method if supported.
– On your device, add the printer via the system’s printer settings.

This method works for many brands including HP and Epson[1][2][4][5].
