If you want to connect the printer to the computer using the WPS method, you need to enter the WPS Pin On Printer. Here, the WPS starts for the Wi-Fi protected setup method, which is an eight-digit number generated by the printer for Wi-Fi connection with the router. Now the question is; where to find the WPS pin? In most of the printer models, the WPS pin is located on the screen of the printer. However, some printers don't have a screen. In such a situation, you can simply refer to the user manual to know about the WPS pin and connection type for your device.
