Printing device capable of authorizing printing limitedly according to user level, printing system using the same and printing method thereof
First Claim
1. A printing device to print data which requires security, comprising:
- an interface part receiving a request to print data by a user and a security level of the data requested to be printed;
an authentication part to determine whether to permit a printing of the data requested to be printed based on whether a pre-stored user level of the user is higher than the security level of the requested data, the authentication part comprising a password processing part to randomly generate a password and transmit the password to the user, the password processing part to determine whether the generated password and a password inputted by the user and obtained by the interface part are equal to each other;
a printing part to print the data requested to be printed; and
a controller to transmit the data requested to be printed received through the interface part to the printing part if the authentication part permits the printing.

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.

6. A printing method of a printing device to print data which requires security, the printing method comprising:
-
receiving a print data request by a user and a security level of the data requested to be printed by the printing device; determining whether to permit a printing with respect to the data requested to be printed based on whether a pre-stored user level of the user is higher than the security level of the requested data and by randomly generating a password, transmitting the generated password externally so that the user receives the password, and determining whether the generated password and a password inputted by the user and received by the printing device are identical to each other; and printing the data requested to be printed if the printing is permitted. - View Dependent Claims (7, 8, 9)

10. A printing system comprising:
-
a file server to store therein data which requires security and a security level of the data; a client to request the data stored in the file server to be printed; and a printing device to receive the data requested to be printed from the file server and the security level of the data, and based on the security level and a pre-stored user level of the user, to determine whether to permit a printing of the data requested to be printed, wherein the printing device includes an authentication part which determines whether to permit a printing with respect to the data requested to be printed based on whether the pre-stored user level is higher than the security level of the requested data, and by randomly generating a password, transmitting the generated password externally so that the user receives the password and determining whether the generated password and a received password inputted by the user through the client are identical to each other. - View Dependent Claims (11, 12, 13)

14. A printing method of a printing system which comprises a file server storing data and security levels of the data, a client requesting data stored in the file server to be printed, and a printing device printing the data requested to be printed, the printing method comprising the operations of:
-
the client transmitting a request for printing to the file server; the file server transmitting the data requested to be printed and the security level of the data to the printing device; the printing device determining whether to permit a printing with respect to the data requested to be printed based on whether a pre-stored user level of the user is higher than the security level of the requested data and by randomly generating a password, transmitting the generated password externally so that the user receives the password, and determining whether the generated password and a received password inputted by the user through the client are identical to each other; and if the printing is permitted, the printing device printing the data requested to be printed. - View Dependent Claims (15, 16, 17)

18. A printing device comprising:
-
an interface part to receive a request to print data by an external source and a security level of the data requested to be printed; an authentication part to determine whether to permit a printing of the data requested to be printed based on whether a pre-stored level of the external source is higher that the security level of the requested data, the authentication part further comprises a password processing part which randomly generates a password and transmits the password to the external source, the password processing part determines whether the generated password and a password inputted by the external source and obtained by the interface part are equal to each other; and a printing part to print the data requested to be printed.
