A printing system can suppress an increase in the processing load of a printer, and facilitate print management. To accomplish this, a printing system includes an authentication unit with which a printer authenticates a user based on account information the user inputs using a host device, a token generating unit with which the printer generates, after the user has been authenticated by the authentication unit, a token containing print function restriction information by referring to information in which the user, and application and the print function restriction are associated with one another, and transmits the token to the host device, a command generating unit with which the host device receives the token to generate a command containing the print function restriction information, and transmits the command to the printer, and a printing unit with which the printer receives the command and executes printing subject to print function restrictions.
