A printing system includes an image forming apparatus and a management server connected via a network. The image forming apparatus reads a card ID of a user of the image forming apparatus from the ID card, accepts non-card authentication information, transmits an authentication request, including the card ID, to the management server, and, if an unsuccessful authentication result is transmitted from the management server, transmits a card registration request, including the non-card authentication information, to the management server. The management server transmits a successful authentication result or the unsuccessful authentication result to the image forming apparatus according to whether the card ID has been registered in correspondence to the user, registers the non-card authentication information in correspondence to the user, and if the non-card authentication information has been registered in correspondence to the user, registers the card ID in correspondence to the user. |
