Abstract:
1. An information processing system, including: an information processing device generating a print job by executing a printer driver; an image forming device producing a printed output in response to the print job received from said information processing device; an authentication server performing authentication of a user who uses said information processing device and said image forming device; and a relay server receiving an authentication request from said image forming device and establishing data communication with said authentication server, thereby sending a response to the authentication request to said image forming device, wherein said information processing device, in sending the print job to said image forming device by executing said printer driver after the user authentication results in success through data communication with said authentication server, attaches authentication information set in advance in said printer driver to the print job and sends to said image forming device, while sending user information indicating that the user is successfully authenticated in said authentication server to said relay server, and said relay server, in response to receipt of the authentication request sent from said image forming device which receives the print job, identifies the user information received from said information processing device based on said authentication information included in the received authentication request and establishes data communication with said authentication server based on the identified user information, thereby verifying if the user is a registered user and sending the response to the authentication request to said image forming device in accordance with the verification result.
