PROBLEM TO BE SOLVED: To provide a printing system capable of preventing failure in authentication due to shortage of authentication information.SOLUTION: A print output device (MFP) 10 acquires transmission source user specification information (for example, MAC address) 151 for specifying a transmission source user of authentication information at the time of reception of authentication information from an external terminal 50 (S13). The MFP acquires request source user specification information (for example, MAC address) 152 for specifying a request source user of a print job at the time of reception of a print job from the external terminal (S16). The MFP determines whether the transmission source user and the request source user are the same on the basis of the transmission source user specification information 151 and the request source user specification information 152 (S17). When determining that the transmission source user and the request source user are the same, the MFP specifies the authentication information from the external terminal as information used for user authentication in printing followed by authentication (S19).SELECTED DRAWING: Figure 4 |
