FIELD: physics, computer engineering.
SUBSTANCE: printing apparatus includes a storage module configured to store printing data, which include a password, when receiving printing data, a receiving module configured to receive a print instruction for the stored printing data from a user, an authentication module configured to perform user authentication, and a printing module configured to perform printing without required input of a password by the authenticated user if the owner of the printing data, based on the print instruction, matches the authenticated user, and perform printing in response to the match between the password received from the user and the password contained in the printing data if the owner of the printing data, based on the print instruction, is different from the authenticated user, and if the print instruction is received without user authentication through the authentication module; a settings module for specifying information indicating whether to perform user authentication, wherein the controller is configured to perform control so as to either make the printing apparatus print data without inputting a password or make the printing apparatus print data in response to password input based on information specified by the settings module.
EFFECT: improved design.
