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 comprising:
- an interface part to receive a request to print data from a user and a security level of the data;
an authentication part to determine whether to permit a printing of the data by comparing the security level and a pre-stored user level of the user, transmit a random password to the user based on a result of the determination, and store the transmitted random password;
a printing part to print the data; and
a controller to transmit the data to the printing part if the authentication part permits the printing and if the stored random password matches a password which the user inputs after confirming the transmitted random password via at least one of email and text message.

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 from a computer a request to print data and an input password from a user via a computer and to receive a security level of the data requested to be printed; determining whether to permit a printing with respect to the data by comparing the security level and a pre-stored user level of the user; transmitting a random password to the user based on a result of the determination and storing the transmitted random password; and printing the data when the printing is permitted and if the stored random password matches another password which the user inputs after confirming the transmitted random password via at least one of email and text message. - View Dependent Claims (7, 8, 9)
