To connect a printer to Wi-Fi, you generally need to access the printer’s control panel or settings menu, find the network or wireless setup option, and then select your Wi-Fi network (SSID) and enter the password. Many modern printers have a built-in wireless setup wizard that guides you through this process directly on the printer screen, without needing a computer[1][3].

If your router supports WPS (Wi-Fi Protected Setup), you can press the WPS button on the router and then press and hold the Wi-Fi or WPS button on the printer for a few seconds to connect automatically without entering a password[1][2].

If your printer doesn’t have built-in Wi-Fi, you can use a wireless print server or a USB Wi-Fi adapter that connects to the printer’s USB port and provides wireless capabilities. These devices usually require separate setup via software or a web interface[3].

In summary:
1. Turn on the printer and access its network or wireless setup menu.
2. Use the wireless setup wizard to find and select your Wi-Fi network.
3. Enter your Wi-Fi password when prompted.
4. Alternatively, use WPS if your router and printer support it by pressing the buttons on both devices.
5. If the printer lacks Wi-Fi, consider a wireless print server or USB Wi-Fi adapter.

Details may vary depending on your printer model and manufacturer. For example, HP printers often guide users via their control panel menus, and Brother printers may require installation of a Printer Setting Tool software on a computer for some configurations[1][2][3].
