FIG. 1 is a diagram of a configuration of an image forming apparatus according to an example.

FIG. 2 is a diagram of a system environment according to an example.

Referring to FIG. 1, an image forming apparatus 100 may include an input/output (I/O) unit 110, a controller 120, a communication unit 130, a memory 140, and an image forming job unit 150. Also, although not illustrated, the image forming apparatus 100 may further include a power supply for supplying power to each component. Also, the image forming apparatus 100 may be an apparatus including an eXtensible Open Architecture (XOA), i.e., an open platform.

The I/O unit 110 may include an input unit for receiving an input of performing an image forming job from a user, and an output unit for displaying a result of performing the image forming job or information about a state of the image forming apparatus 100. For example, the I/O unit 110 may include an operation panel for receiving a user input and a display panel for displaying a screen.

In more detail, the input unit may include a device capable of receiving various types of user input, such as a keyboard, a physical button, a touch screen, a camera, or a microphone. Also, the output unit may include a display panel or a speaker. However, the I/O unit 110 is not limited thereto, and may include an apparatus supporting various inputs and outputs.

The I/O unit 110 may include an independent control system. In other words, separate from the controller 120 of the image forming apparatus 100, the I/O unit 110 may include a control system (e.g., a controller and a memory) for controlling a user interface (UI) provided by the I/O unit 110. The control system of the I/O unit 110 may include an operating system (OS) for providing a UI and programs, such as applications, for supporting various functions.

The controller 120 may control overall operations of the image forming apparatus 100, and may include a processor, such as a central processing unit (CPU). The controller 120 may control other components included in the image forming apparatus 100 to perform an operation corresponding to a user input received through the I/O unit 110.

For example, the controller 120 may execute a program stored in the memory 140, read a file stored in the memory 140, or store a new file in the memory 140.

When job information about printing of content and identification (ID) information are received from an external apparatus or a server connected to the external apparatus through the communication unit 130, ID information is received from a user through an input unit of the I/O unit 110. If the ID information received from the user and the received ID information correspond to each other, the controller 120 may control the communication unit 130 to transmit billing information based on the job information to a payment system. When payment completion information according to payment of the user is received through the communication unit 130, the controller 120 may print the content based on the job information.

The ID information received through the input unit and the ID information received through the communication unit 130 may be determined to correspond to each other when they match each other.

The controller 120 may control the communication unit 130 to transmit content print completion information according to completion of printing of the content to the payment system.

When the ID information received through the input unit and the ID information received through the communication unit 130 correspond to each other, the controller 120 may control the output unit of the I/O unit 110 to display a job information list including the job information, and when the job information is selected from the job information list, the controller 120 may control the communication unit 130 to transmit the billing information based on the job information to the payment system.

The communication unit 130 may communicate with another device or a network via wired or wireless communication. In this regard, the communication unit 130 may include a communication module supporting at least one of various wired/wireless communication methods. For example, the communication module may be in a form of a chipset, or may be a sticker/barcode (for example, a sticker including a near field communication (NFC) tag) containing information required for communication.

The wireless communication may include at least one of, for example, wireless fidelity (Wi-Fi), Wi-Fi direct, Bluetooth, ultra wideband (UWB), and NFC. The wired communication may include at least one of, for example, a universal serial bus (USB) and a high definition multimedia interface (HDMI).

The communication unit 130 may be connected to an external apparatus 200 located outside the image forming apparatus 100 so as to transmit or receive a signal or data. Referring to FIG. 2, the image forming apparatus 100 may be connected to the external apparatus 200 through the communication unit 130. The communication unit 130 may transmit a signal or data received from the external apparatus 200 to the controller 120, or transmit a signal or data generated by the controller 120 to the external apparatus 200. For example, when the communication unit 130 receives a print command signal and print data from the external apparatus 200, the controller 120 may output the received print data through a printer 151.

As illustrated in FIG. 2, the image forming apparatus 100 may be connected to the user terminal 200 or a server 300.

As shown in FIG. 2, the external apparatus 200 may include an I/O unit 210, a controller 220, a communication unit 230, and a memory 240. The controller 220 may control an image forming job by executing a program stored in the memory 240 and transmitting a signal or data generated as a result to the image forming apparatus 100 through the communication unit 230. The external apparatus 200 may include, for example, a smart phone, a tablet personal computer (PC), a PC, a home appliance, a medical device, a camera, or a wearable device.

The communication unit 130 may be directly connected to the server 300 to transmit or receive a signal or data. Also, the communication unit 130 may be connected to the external apparatus 200 through the server 300. In other words, the communication unit 130 of the image forming apparatus 100 may transmit or receive a signal or data to and from the communication unit 230 of the external apparatus 200 through the server 300.

Referring back to FIG. 1, various types of data, such as programs (for example, applications) and files, may be installed or stored in the memory 140. The controller 120 may access and use the data stored in the memory 140 or store new data in the memory 140. Also, the controller 120 may execute a program stored in the memory 140. Also, the controller 120 may install an application received from an external source through the communication unit 130 in the memory 140.

The image forming job unit 150 may perform an image forming job, such as copying, printing, scanning, or faxing.

In the example of FIG. 1, the image forming job unit 150 includes the printer 151, a scanner 152, and a facsimile machine 153, but the image forming job unit 150 may include only some of them or may further include a component for performing another type of image forming job according to needs.

The printer 151 may form an image on a recording medium via any one of various printing methods, such as an electro-photography method, an inkjet method, a thermal transfer method, and a thermo-sensitive method.

The scanner 152 may irradiate light onto paper and read an image recorded on the paper by receiving light reflected from the paper.

In the facsimile machine 153, a component for scanning an image may be shared with the scanner 152, and a component for printing a received file may be shared with the printer 151. The facsimile machine 153 may transmit a scan file to a destination or receive a file from an external source.

FIG. 3 is a block flow diagram for describing a job related to content according to an example.

Referring to FIG. 3, a system may include the image forming apparatus 100, the external apparatus 200, the server 300 (for example, a cloud server), a payment system 400, and a payment agency 500. The payment system 400 may include a payment apparatus 401 for payment of job expenses using the image forming apparatus 100, and a payment server 402 for managing a job history of the image forming apparatus 100.

In this case, components of the system may be connected to each other through a communication network. For example, the image forming apparatus 100, the external apparatus 200, and the server 300 may be connected to each other via long distance wireless communication, and the image forming apparatus 100 and the payment apparatus 401 may be connected via short distance wireless communication or wired communication. The payment apparatus 401 may be attached to the image forming apparatus 100 or provided adjacent to the image forming apparatus 100.

According to an example, when a user requests content to be printed by using a PC 202, i.e., an example of the external apparatus 200, the PC 202 may transmit job information about a job related to the content to the image forming apparatus 100, in operation 301.

A job related to content may be a job related to printing, scanning, faxing, or copying of the content.

Also, job information may include at least one of a job type, a job ID, content, a job option, and the like. A job type may be information about whether a job of the image forming apparatus 100 is a printing job, a scanning job, a faxing job, or a copying job. A job option (for example, a print option) may include at least one of a size of printing paper, color printing, double-sided printing, the number of printouts, the number of pieces of scanned paper, and the number of copies. Content may be rendered in a format of print data.

As another example, when the user requests the content to be printed by using a smart phone 201, i.e., another example of the external apparatus 200, the smart phone 201 may transmit the job information to the server 300, in operation 302. In this case, the user may request the content to be printed by using a job application installed in the smart phone 201. The server 300 may render the content requested to be printed by the user to a format of print data, and transmit the rendered content and the job information to the image forming apparatus 100, in operation 303.

When the user requested the content to be printed, the external apparatus 200 may receive ID information (for example, a personal identity number (PIN), a password, etc.) from the user. Also, the external apparatus 200 may transmit the received ID information to the image forming apparatus 100. At this time, the external apparatus 200 may transmit the received ID information to the image forming apparatus 100 together with the job information, or inside the job information.

The ID information may be generated in units of job information about printing of the content, in units of content, or in units of the external apparatus 200. When the ID information is generated in units of the external apparatus 200, the ID information may be generated, for example, in units of a type of the external apparatus 200, ID information of the external apparatus 200, an internet protocol (IP) address used by the external apparatus 200, and the like.

When the ID information is generated in units of the job information, the ID information needs to be input whenever the user requests printing. Also, when the ID information is generated in units in relation to the external apparatus 200, the user does not need to additionally input the ID information when requesting printing using the external apparatus 200 once the user has input the ID information during an initial request for printing.

When the ID information (for example, a phone number assigned to a smart phone) pre-exists in the external apparatus 200, the external apparatus 200 may transmit the assigned ID information together with the job information to the image forming apparatus 100, without a separate input from the user. Alternatively, when the assigned ID information is transmitted to the server 300 together with the job information, the server 300 may transmit the received ID information to the image forming apparatus 100.

As described in the above examples, when the job information and the ID information are transmitted to the image forming apparatus 100, the image forming apparatus 100 may receive the job information and the ID information.

The user may move to the image forming apparatus 100 and input ID information through the I/O unit 110 of the image forming apparatus 100. The image forming apparatus 100 may determine whether the input ID information and the ID information received from the external apparatus 200 or server 300 correspond to each other. For example, the image forming apparatus 100 may determine whether the input ID information and the received ID information match each other. Alternatively, when the user pre-registered unique information in the image forming apparatus 100, the image forming apparatus 100 may determine whether the input ID information matches information in which the received ID information and the unique information are combined.

When it is determined that the input ID information and the received ID information correspond to each other, the image forming apparatus 100 may transmit billing information based on the job information to the payment system 400.

The billing information may include information about a payment method. For example, the billing information may include information about a payment device, a payment method, a payment application, a payment server, and the like.

The billing information may include payment method information and payment amount information corresponding to job expenses of the job information. The billing information may include information about a job, payment amount information, payment apparatus information, payment server information, and the like.

The billing information may include, for example, job expenses (for example, print expenses) and at least some of the job information. At least some of the job information may be at least one of, for example, job ID, a print option, a job type, and the like.

Job expenses may be determined based on a job option. For example, the job expenses may increase when the size of printing paper is large, color printing is set, the number of printouts is high, and the like. Alternatively, the job expenses may decrease when the size of printing paper is small or double-printing is set.

The payment system 400 may include at least one of the payment apparatus 401 and the payment server 402.

For example, the image forming apparatus 100 may transmit the billing information to the payment apparatus 401 (for example, a card terminal) of the payment system 400, in operation 304.

Upon receiving the billing information, the payment apparatus 401 may transmit the billing information to the payment server 402, in operation 305. In this case, the payment apparatus 401 may receive registration result information indicating that the billing information is registered, from the payment server 402 that received the billing information.

The payment apparatus 400 may display the job expenses included in the billing information for printing content. Upon checking the job expenses, the user may request payment by using the payment apparatus 401. For example, the user may request payment by using a credit card, a debit card, a transportation card, a Cashbee card, a rechargeable card (for example, a T-money card), a Payon method, or a Coin method. When the user requests payment, the payment apparatus 401 may transmit payment request information to the payment agency 500 (for example, a Value Added Network (VAN)), in operation 306. The payment request information may include, for example, at least one of a credit card number, a payment amount, transaction ID, ID information of the payment apparatus 401, and the like.

When payment is approved based on the received payment information, the payment agency 500 may transmit payment approval information to the payment apparatus 401 in operation 307. The payment approval information may include at least tone of, for example, an approval number, an approval result, and an approval date and time.

The payment apparatus 401 may transmit payment completion information according to the approval of payment to the payment server 402, in operation 308. The payment completion information may include at least one of job ID, transaction ID, job expenses, a credit card number, a payment result, and the like. At this time, the payment apparatus 401 may receive registration result information indicating that the payment completion information is registered from the payment server 402 that received the payment completion information.

Also, the payment apparatus 401 may transmit the payment completion information according to the approval of payment to the image forming apparatus 100, in operation 309.

Upon receiving the payment completion information, the image forming apparatus 100 may perform the job related to content based on the job information received in operations 301 and 303.

Also, the image forming apparatus 100 may transmit, to the payment server 402, job completion information according to completion of the job related to the content. The job completion information may include, for example, at least one of job ID, a job option, a job result, and the like. At this time, the image forming apparatus 100 may receive registration result information indicating that the job completion information is registered from the payment server 402 that received the job completion information.

The payment server 402 may manage a job history of the image forming apparatus 100 based on at least one of the billing information, the payment completion information, the job completion information, and the like.

For example, the content may not be printed even when the user has made payment. In this case, the user may access the payment server 402 (for example, access a service website or call an adviser) to request the content to be printed again. At this time, the payment server 402 may determine why the job related to content is not performed, based on the job history according to at least one of the billing information, the payment completion information, and the job completion information, and provide the user with feedback.

According to various examples, in the system of FIG. 3, there may be a plurality of the image forming apparatuses 100. In this case, the job information received by one of the plurality of image forming apparatuses 100 may be transmitted to another of the plurality of image forming apparatuses 100. For example, when a size of a job according to job information assigned to one image forming apparatus is equal to or greater than a threshold value, the image forming apparatus may redistribute the job to another image forming apparatus having a small-sized job. In this case, information about the image forming apparatus 100 that is to print the content requested by the user may be provided to the user. For example, ID information of the image forming apparatus 100 that is to print the content (for example, ID, a product name, or location information of the image forming apparatus 100) may be displayed through the external apparatus 200, displayed through the image forming apparatus 100 being manipulated by the user, or displayed through a separate guide display.

The user may conveniently receive a charged service for printing content by using a payment apparatus through the image forming apparatus 100.

The image forming apparatus 100 may self-generate payment information to proceed with payment without regard to a type of a payment method. Also, the image forming apparatus 100 may generate billing information for not only a job using a printing and copying function of the image forming apparatus 100, but also a job using a scanning and faxing function of the image forming apparatus 100.

Also, the image forming apparatus 100 may generate billing information in units of job information using the image forming apparatus 100 so as to prevent a job from being partially completed. Also, the image forming apparatus 100 may pre-calculate a payment amount according to job information of content and display the payment amount to the user such that the user may select a payment method based on the payment amount.

FIG. 4 is a flow diagram of a method of generating billing information including job information and payment method information according to an example.

Referring to FIG. 4, a user 1 may transmit job information of content to the image forming apparatus 100 in operation S401. The job information may include information about which one of a printing job, a scanning job, a faxing job, a copying job, and the like is a job of the image forming apparatus 100. A job option (for example, a print option) may include at least one of a size of printing paper, color printing, double-sided printing, the number of printouts, the number of pieces of scanned paper, the number of copies, and the like. The content may be rendered to a format of print data.

In operation S402, the image forming apparatus 100 may determine a payment amount based on the job information. The image forming apparatus 100 may determine the payment amount based on amount information pre-determined according to job options.

In operation S403, the image forming apparatus 100 may receive payment method information from the user 1. The payment method information may denote a payment method used by the user 1 to pay the payment amount.

As an example, the image forming apparatus 100 may display a list of payment methods together with job expenses included in the billing information. Upon checking the job expenses, the user 1 may request payment by selecting a payment method. For example, the user 1 may request payment by using a credit card, a debit card, a transportation card, a Cashbee card, a rechargeable card (for example, a T-money card), a Payon method, or a Coin method.

In operation S404, the image forming apparatus 100 may generate billing information.

The image forming apparatus 100 may generate information related by payment by using the second application 122. For example, the image forming apparatus 100 may generate payment amount information 125 and billing information 126 by using the second application 122.

The second application 122 may generate the payment amount information 125 by using job information of content received from the first application 121 that performs the job of the image forming apparatus 100. For example, when the job information includes information about “A4 size color printing 1 page,” the payment amount information 125 of “200 won” may be generated based on pre-determined payment amount setting information.

The second application 122 may generate the billing information 126 based on the job information received from the first application 121 that performs the job of the image forming apparatus 100, pre-determined payment amount information, payment method information received from a user, and the like. For example, when the user inputs “credit card” as a payment method, the billing information 126 may be generated by matching the payment amount “200 won” with respect to the job information “A4 size color printing 1 page,” to the payment method information of “credit card.”

The image forming apparatus 100 may provide, to the payment system 400, the payment amount information 125 and the billing information 126 generated by using the second application 122 so as to perform unmanned payment without having to use a foreign device interface (FDI) device.
