Wi-Fi Protected setup is an application which is used for setting up the connection between the router and the wireless printer. The application enables the user to print any file or documents anywhere all around the world. It allows the user to get connected with the wireless printer through WPS PIN code with the wired network and the wireless router. It is regarded as secure as the printing is possible after entering the PIN for the authentication.
