To connect a printer to Wi-Fi, you typically have three main methods:

1. **Wireless Setup Wizard on Printer:** Use the printer’s built-in menu (usually under Network or Wireless Settings) to select your Wi-Fi network (SSID) and enter its password. This requires the printer to have a screen and buttons or touchscreen. The setup wizard guides you through connecting to the network[1][5].

2. **WPS Button Method:** If both your printer and router support WPS (Wi-Fi Protected Setup), press the WPS button on your router, then on the printer (usually held for a few seconds or selected via the printer menu). The devices connect automatically without needing to input a password[1][3].

3. **Using an Ethernet Cable for Configuration:** Connect your printer to the router with an Ethernet cable, find the printer’s IP address via the router’s admin page, then access its web interface through a browser to configure wireless settings manually[1].

Additional tips:

– After connecting, verify the connection by printing a network configuration page from the printer, showing IP and MAC addresses[1].
– Make sure the printer is within Wi-Fi range and powered on.
– If problems occur, consult the printer manual or router settings for troubleshooting[1][4].

For specific brands:

– **HP:** Use the Wireless Setup Wizard or WPS button; the wireless light will stop blinking when connected[3][5].
– **Epson:** Use Home button and Wi-Fi Setup Wizard on the control panel to select network and enter password[5].
– **Canon:** Use Home and WLAN setup buttons to select network from the list and enter password; indicator lights show connection status[5].

These methods are broadly applicable, but exact steps may vary slightly depending on your printer model. Always check your printer’s manual for detailed instructions tailored to your device.
