Patent ID: 8913267

Claim:
A printing system having a printing means performing printing based on print data, comprising: a plurality of printer apparatuses; a print data supplying apparatus for supplying print data to the printer apparatuses; an input portion for receiving print instructions from a user; a print attribute setting means for performing setting of print attributes comprising receiving from the input portion security attributes for the print data input by the user during the input of the print instructions for instructing formation of the print data from the user and setting the security attributes for the print data; a print data restricting means for determining whether to provide the print data to each of the printer apparatuses based on the security attributes for the print data and the security attributes based on a degree of safety of an installation environment of each of the printer apparatuses; an authentication information input means for inputting authentication information for authenticating print instruction authority of the user carrying out print instructions; and an authentication means for authenticating the print instruction authority of the user based on authentication information inputted by the authentication information input means, wherein a trigger for a start of a print processing occurs upon detection of availability of reading of the authentication information, wherein the print data restricting means identifies printer apparatuses that are permitted to print based on the print instruction authority authenticated by the authentication means, wherein the printing system restricts printing the data on a printer apparatus identified by the print data restricting means when the security attributes for the print data has a security level higher than the security attributes of a printer apparatus among the printer apparatuses.
