System and method of managing shared printer with RFID
First Claim
1. A shared printer to print documents based on a task permission level of a user obtained through radio frequency identification (RFID) information, the shared printer comprising:
- an RFID transceiver unit to periodically retrieve the RFID information including at least one of an ID of a user and the task permission level of one or more corresponding RFID chips;
a controller to determine whether to perform a print task based on the retrieved RFID information and to control the printing by the shared printer based on the determination; and
a memory unit to store log information including a print count value corresponding to the RFID chip when the print task is completed,wherein if the user ID retrieved by the RFID transceiver unit is determined to be a pre-stored ID in the memory unit, the controller reduces a print count value corresponding to the RFID chip in the memory unit.

Abstract
A system and method of managing a shared printer with radio frequency identification (RFID) includes at least one RFID chip containing information about task permission for users, an RFID transceiver unit to periodically retrieve information about the RFID chip, a controller to determine whether to output a document based on task permission held by a user associated with the RFID chip retrieved by the RFID transceiver unit, and a printing unit to form images on a printing medium in response to a control signal from the controller. It is possible to allow, for example, printing and facsimile transmission by giving specific permission to each user and allows a manager to inspect a use specification by the RFID transceiver unit. The RFID transceiver unit is included in a printer and periodically retrieves information about an RFID chip and determines whether a document is to be output based on task permission held by a user associated with the retrieved RFID chip.

7. A method of controlling a shared printer with RFID to perform different tasks for users based on an authorized task permission level, the method comprising:
-
retrieving RFID chip information including user information from an external source; performing the printing task corresponding to the retrieved RFID chip information if the retrieved RFID chip information includes the task permission level authorized to perform the task; determining whether the retrieved RFID chip information corresponds to a new ID or a previously stored ID, and if the retrieved RFID chip information corresponds to a new ID, registering the new ID in a memory unit; and adjusting and storing an ID specific printing count value corresponding to a number of pages used in performing the task. - View Dependent Claims (8, 9)

10. An image forming apparatus comprising:
-
a radio frequency identification (RFID) unit to retrieve information from a user regarding a level of user access to the image forming apparatus; a controller to control the level of user access to the image forming apparatus based upon the level of user access; and a memory unit to store log information including a print count value corresponding to the RFID unit, wherein the RFID unit transmits and retrieves RFID information from RFID chips at uniform time intervals.
