An authenticated printing system includes a job creation unit that creates a print job in accordance with a direction of a user, a job holding unit that holds the print job created by the job creation unit, an authentication information acquisition unit that generates authentication information based on information acquired from an authentication device, an authentication unit that receives the authentication information generated by the authentication information acquisition unit and performs authentication of an user on the basis of the authentication information, and a print unit that acquires the print job of an authenticated user from the job holding unit and prints the print job in a case where the user is authenticated by the authentication unit. The authentication unit includes a process section that acquires the authentication information of an owner of the print job from a database and stores the authentication information in a cache as authentication usable information when the print job is held by the job holding unit, and a process section that performs the authentication of a user based on whether the authentication information generated by the authentication information acquisition unit is stored in the cache.
