An information processing terminal transmits, to an authentication server, information obtained by imaging a code pattern of multifunction device information, and authentication information inputted by a user. The authentication server performs user authentication based on the received authentication information and specifies a multifunction device based on the received information of the code pattern. If the user has been authenticated, the authentication server transmits print data corresponding to the user to the multifunction device and prescribes the execution of print processing to the multifunction device. The multifunction device executes print process based on the obtained print data.
