## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority under 35 U.S.C. §119(a) from Korean Patent Application No. 10-2007-0096136, filed on Sep. 20, 2007 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present general inventive concept relates to a printing system which charges to print a document, and a method of charging to print therein.
2. Description of the Related Art
In general, a printing system receives a printing signal from a plurality of host apparatuses which are connected thereto on a network and prints a document. Here, charging to the document printing is typically made to a user who gives a printing command, or may be made to other people, such as a document maker.
Japanese Patent First Publication No. 2006-227703 discloses a method of charging for printing to a document maker. The document maker stores a document to be printed in a printer server, and then, a user accesses to the printer server to retrieve the concerned document and give a printing command. Here, charging for the printing is made to the document maker after identifying a registration number of the document stored in the printer server.
However, according to this conventional method, a document to be printed should be stored in a printer server to determine who is to be charged for printing, and thus, larger storing part is needed for more documents, thereby increasing expenses for the storing part.
Further, in the conventional method, a user should retrieve a document to be printed which is stored in a printer server, which causes an inconvenience to the user and requires time for retrieving the document. According to circumstances, it may be difficult for a user to retrieve a desired document.
Furthermore, the conventional method, which requires networking for document retrieving and printing command transmission, cannot be applied to the case that a user does not use a personal computer, for example, the case that a user uses a USB memory for printing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
Referring to FIGS. 1 and 2, a printing system 10 according to an exemplary embodiment of the present general inventive concept may include at least one server 11 and a printing apparatus 12. The printing apparatus 12 may be provided as a multi function device, a printer, or the like. The server 11 may be provided in the printing apparatus 12.
As illustrated in FIG. 1, the server 11 may include a storing part 110, a host communication part 120, a user input part 130, and a host controller 140.
The storing part 110 stores information on a plurality of document registrants. The document registrant refers to a person who may be charged to print a document, for example, a document maker.
The storing part 110 may further store reference information to determine whether or not a document to be printed corresponds to a user's wanted document. The reference information may include information on a document maker, a file name, a recent revision date, a file size, a checksum, etc., and may be stored in the form of an information table.
Referring to FIG. 2, the reference information may be stored in the storing part 110 by a document registrant A 20 or any other manager.
The host communication part 120 receives a document (for example, x.pdf document) which contains predetermined relevant information from a user. The user gives a printing command to the server 11, and may be embodied into a host device of the printing apparatus 12 in the present general inventive concept. In this case, the server 11 receives a document to be printed through the host communication part 120 from the user, and at the same time, receives the printing command from the user. Referring to FIG. 2, a user B 30 and a user C 40 can receive the document (for example, x.pdf document) from the document registrant A 20 through a separate route, such as an e-mail or a USB driver.
The host communication part 120 may be embodied into a wired or wireless communication module which is to be connected through a network, or into a USB port. For example, the server 11 may receive a document through a network from a personal computer of the user B 30, that is, the host device 12, or may directly receive a document through a USB driver from the user C 40.
The host communication part 120 transmits the document to the printing apparatus 12 to print.
The user input part 130 receives authority information to print the document from a user.
More particularly, a user may log-in to access the server 11 using an ID and a password. Such a log-in process may be required when the user B 30 accesses the server 11 through a network or the user C 40 directly transmits a document through a USB driver.
The user input part 130 may be provided as a control panel which is provided to the server 11 to receive an instruction from the user C 40.
The host controller 140 charges the print job to the document registrant A 20 who corresponds to the document received through the host communication part 120 among the document registrants registered in the storing part 110.
More particularly, the host controller 140 reads relevant information, such as a document registrant, a file name, a file size, a recent revision date, etc. from the received document, and compares the relevant information with the reference information stored in the storing part 110 to determine an identity of the document. Then, the host controller 140 charges the document registrant A 20 to print the document depending on the determination. The host controller 140 may re-identify the document through the checksum included in the relevant information.
The host controller 140 may charge the print job to the user B 30 or the user C 40 who gives a printing command if the reference information corresponding to the relevant information of the received document does not exist in the storing part 110.
The host controller 140 updates the charging and printing results into the information table of the storing part 110. The updated information table may be referred to by the document registrant A 20 anytime when necessary. The updated charging and printing results may be notified to a person who is to be charged through the host communication part 120, or may be displayed through a display unit (not illustrated).
The host controller 140 may request the document registrant A 20 approval to charge to print the document through the host communication part 120, and may authenticate the charging based on the approval.
On the other hand, the document registrant A 20 may establish a period of time to print the document when registering the reference information. If a printing period of time is established, the host controller 140 determines whether or not the printing period of time elapses when receiving a printing command and performs printing depending on the determination.
As illustrated in FIG. 1, the printing apparatus 12 may include an image forming part 210, a printer communication part 220, and a printer controller 240.
The image forming part 210 forms an image to print based on printing data under the control of the printer controller 240. The image forming part 210 may employ one of an ink-jet method, a laser method, and other methods known in the art.
The printer communication part 220 performs communication with the server 11.
The printer controller 240 controls the printing apparatus 12. In more detail, the printer controller 240 controls the image forming part 210 to form an image for a document received through the printer communication part 220, and controls the printer communication part 220 to transmit a printing result to the server 11 after document printing is completed.
Hereinafter, a method of charging to print a document in the printing system 10 which includes the server 11 and the printing apparatus 12, according to an exemplary embodiment of the present general inventive concept, will be described with reference to FIG. 3.
First, the server 11 receives a document including relevant information through the host communication part 120 from a user in operation S100.
Then, the printing apparatus 12 receives the document from the server 11 and prints it in operation S200.
Next, the server 11 charges a document registrant corresponding to the received document for the document printing in operation S300.
Hereinafter, a method of charging to print a document according to another exemplary embodiment of the present general inventive concept will be described with reference to FIG. 4.
First, the server 11 registers reference information in the storing part 110 by a document registrant or any other manager in operation S110.
Then, the server 11 receives authority information, for example, an ID or a password given to a user, through the user input part 130 from the user, and determines the identity of the user in operation S120.
Next, the server 11 receives a document including relevant information from the registered user of operation S120 in operation S130. Here, the relevant information may include a document registrant, a file name, a file size, a recent revision date, a checksum, or the like.
Next, the printing apparatus 12 receives the document from the server 11 and prints it in operation S140.
The host controller 140 reads the relevant information from the document received in operation S130, and compares the relevant information with the reference information registered of operation S110 in operation S150, and determines whether or not the relevant information and the reference information are the same in operation S160.
If it is determined that the relevant information and the reference information are the same, the server 11 charges the document registrant for the document printing in operation S170. Here, the server 11 may request the document registrant approval for the charging.
If it is determined that the relevant information and the reference information are not the same, the server 11 charges a user who gives a printing command for the document printing in operation S180.
Then, the server 11 updates the printing and charging results into the storing part 110, and notifies the updated results to the charged document registrant or user in operation S190.
As described above, according to a printing system and a method of charging to print a document according to the present general inventive concept, the capacity of a storing part can be minimized when charging to print to a person other than a user who gives a printing command.
Further, it is possible to conveniently and promptly charge to print a document to a person other than a user who gives a printing command.
Furthermore, it is possible to charge to print a document to a person other than a user who gives a printing command, even when printing a document through a connection means other than a network.
The present general inventive concept can also be embodied as computer-readable codes on a computer-readable medium. The computer-readable medium can include a computer-readable recording medium and a computer-readable transmission medium. The computer-readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. The computer-readable transmission medium can transmit carrier waves or signals (e.g., wired or wireless data transmission through the Internet). Also, functional programs, codes, and code segments to accomplish the present general inventive concept can be easily construed by programmers skilled in the art to which the present general inventive concept pertains.
Although a few exemplary embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
