ABSTRACT:
A printing device which authorizes a printing limitedly according to a user level, a printing system using the same and a printing method thereof. The printing device includes an interface part receiving a printing data requested by a user and a security level of the requested printing data; an authentication part determining whether to print the requested printing data based on the security level and a pre-stored user level of the user; a printing part printing the requested printing data; and a controller transmitting the requested printing data received through the interface part to the printing part if the authentication part permits the printing. Accordingly, even if a user obtains an access to the system, because the user has a limitation in using and printing the data depending on his/her position or job, the security of the data can be more effectively guaranteed.
