Image forming apparatus for controlling an image forming job input in an offline state and controlling method thereof
An image forming apparatus and a controlling method thereof are provided. The image forming apparatus includes a communication interface unit which is connected to a server where on-line output quota information set for each user is stored, a storage unit which stores off-line output quota information received from the server, a controller which, when a job command is input in an on-line state where communication with the server is available, determines whether to perform a job based on on-line output quota information stored in the server, and when the job command is input in an off-line state where communication with the server is cut off, determines whether to perform a job based on the off-line output quota information stored in the storage unit, and an image forming unit which, when job performance is determined by the controller, performs an image forming job corresponding to the job command.
1. An image forming apparatus, comprising:
a communication interface unit which is connected to a server where on-line output quota information set for each user is stored;
a storage unit which stores off-line output quota information received from the server;
a controller which, when a job command is input in an on-line state where communication with the server is available, determines whether to perform a job based on on-line output quota information stored in the server, and when the job command is input in an off-line state where communication with the server is cut off, determines whether to perform a job based on the off-line output quota information stored in the storage unit; and
an image forming unit which, when job performance is determined by the controller, performs an image forming job corresponding to the job command,
wherein the controller, when an available amount of usage is not enough for a type of an input job command, determines whether to perform a job by replacing the available amount with that of another type of job command included in the off-line output quota information.
2. The apparatus as claimed in claim 1 , wherein the on-line output quota information and the off-line output quota information includes information regarding an allowed amount of usage, an amount of usage, and an available amount of usage.
3. The apparatus as claimed in claim 1 , wherein the controller, when communication with the sever becomes available again after an image forming job is performed based on the off-line output quota information in the off-line state, updates output quota in the server in accordance with the performed image forming job and initializes the off-line output quota information.
4. The apparatus as claimed in claim 1 , wherein the off-line output quota information is categorized according to a type of job command.
5. The apparatus as claimed in claim 1 , wherein the controller updates the on-line output quota information in the storage unit and the server whenever a predetermined amount of image forming job is performed.
6. A method of controlling an image forming apparatus, comprising:
connecting to a server where on-line output quota information set for each user is stored;
storing off-line output quota information received from the server;
when a job command is input in the on-line state where communication with the server is available, determining whether to perform a job based on on-line output quota information stored in the server, and when the job command is input in an off-line state where communication with the server is cut off, determining whether to perform a job based on the off-line output quota information stored in the storage unit; and
performing an image forming job corresponding to the job command when the determination is made to perform the job,
wherein the off-line output quota information is categorized according to type of job command, and
wherein the determining comprises, when an available amount of usage is not enough for a type of an input job command, determining whether to perform a job by replacing the available amount with that of another type of job command included in the off-line output quota information.
7. The method as claimed in claim 6 , wherein the on-line output quota information and the off-line output quota information includes information regarding an allowed amount of usage, an amount of usage, and an available amount of usage.
8. The method as claimed in claim 6 , further comprising:
when communication with the sever becomes available again after an image forming job is performed based on the off-line output quota information in the off-line state, updating output quota in the server in accordance with the performed image forming job and initializing the off-line output quota information.
9. The method as claimed in claim 6 , wherein the off-line output quota information is categorized according to type of job command.
10. The method as claimed in claim 6 , further comprising:
updating the on-line output quota information in the storage unit and the server whenever a predetermined amount of an image forming job is performed.
11. A non-transitory computer readable recording medium containing code to perform a method of controlling an image forming apparatus, the method comprising:
connecting to a server where on-line output quota information set for each user is stored;
storing off-line output quota information received from the server;
when a job command is input in the on-line state where communication with the server is available, determining whether to perform a job based on on-line output quota information stored in the server, and when the job command is input in an off-line state where communication with the server is cut off, determining whether to perform a job based on the off-line output quota information stored in the storage unit; and
performing an image forming job corresponding to the job command when the determination is made to perform the job,
wherein the off-line output quota information is allocated by the server separately from the on-line output quota information,
wherein the determining comprises, when an available amount of usage is not enough for a type of an input job command, determining whether to perform a job by replacing the available amount with that of another type of job command included in the off-line output quota information.
