PROBLEM TO BE SOLVED: To protect print-out from a printer without previously performing user registration or the like to that printer. SOLUTION: When print data 100 are transmitted from a client device 20 to a printer system 10, the printer system 10 applies a unique authentication code 110 to these print data 100 and correspondently stores this authentication code 110 and the print data 100. Then, the printer system 10 returns that authentication code 110 to the client device 20 as a transmitting source of the print data 100. When a user moves to the printer system 10 and inputs that authentication code, the print system 10 prints out the print data 100 corresponding to that code.
