a user terminal that issues a print job containing print data;

a management server that receives and stores the print job issued by the user terminal; and

an information output unit that acquires print data from the management server and executes printout,

wherein the user terminal, the management server, and the information output unit are connected through a network,

wherein the user terminal transmits a print job specifying a print reception user of a print data recipient to the management server,

wherein the information output unit includes:

a camera that acquires user image information;

a communication section that transmits the user image information acquired by the camera to the management server; and

a print section that executes printout,

wherein the management server includes:

a print job processing section that stores and manages the print job received from the user terminal in a print information database in association with a user identifier of the print reception user; and

a user authentication section that receives the user image information from the information output unit and executes user authentication based on comparison processing between the received user image information and registered user image information associated with a registered user stored in a user information database, and

wherein provided that the user is authenticated in the user authentication section, the print job processing section executes processing of acquiring print job data with the authenticated user set as the print reception user from the print information database and of transmitting the print job data to the information output unit.
