This invention relates to a network printing system and more particularly a billing mechanism for a network printing system that employs token credits as a measurement of printer device usage.
The prior art is replete with methods for obtaining billing information in printer systems. For example, U.S. Pat. No. 3,974,363 discloses a programmable billing system for use in a stand-alone reproduction machine. The system provides means for counting reoccurring events and generating a weighted output value proportional to the billing value of the events. It is also known, as disclosed in U.S. Pat. No. 5,305,199, to employ a single tracking system for monitoring inventories of supplies consumed by a network of reprographic machines. Furthermore, U.S. Pat. No. 6,216,113 B1 discloses a network administrator which stores data representing usage of selected printers and a decoder for validating a print job request and a billing account number. The print jobs are verified and billed to an individual or group account number.
A difficulty with the above described techniques is a lack of capability to charge individuals or groups of individuals for usage of the printers on the network. Another difficulty is the lack of a simple method to determine the measurement of the usage of the devices. For example, U.S. Pat. No. 6,216,113 B1 uses various counters and totalizers circuits which count and accumulate device usage information. The system requires at least one counter circuit for every possible operation of the device.
In one aspect, the invention is an electronic transaction recording system for accumulating data from printer devices comprising: a billing manager which controls the billing polices for each printer device, a billing system which accumulates information on the occurrence of predetermined events and generates an accounting of usage based on the accumulated information and associates the accounting of usage with a predetermined unit of usage, and a database for storing a user's account information in terms of the predetermined unit of usage. Also, the billing system periodically updates the user's account information and issues a bill to the user. Preferably, the predetermined unit of usage is a token. Also, the system may include an apparatus for associating a predetermined number of tokens for each predetermined event and receiving from each printer device the total number of predetermined events that took place at each printer device and determining the token charge and assigning the token charge to an account. Furthermore, the system may include a billing policies database, which includes billing policies for the printer devices such that each printer device uses at least one billing policy to determine the cost of each operation performed on the printer. The cost of the operation is preferably illustrated in tokens. Optionally, the system further comprises a mobile access unit coupled to the billing manager via the printer device. The mobile access unit can be a personal digital assistant, wireless telephone or mobile computer. The system may further comprise a user configuration unit coupled to the billing polices database for updating and configuring billing polices for new users. The billing manager may include at least one memory device and a processor. Also, the billing system can be either a back office billing system or an Internet Settlement Model. Furthermore, the user can authorize the charges before the document is printed and the user's identify is authenticated by the system by submitting user credentials.

The system may further comprise a billing policies database, which includes billing policies for the printer device such that each printer device uses at least one billing policy to determine the cost of each operation, performed on the printer. Furthermore, the mobile access unit can be a personal digital assistant, wireless telephone or mobile computer. Also, the mobile access unit transmits using a wireless link. The system may further comprise a user configuration unit coupled to the billing polices database for updating and configuring billing polices for new users. The billing system may include at least one memory device and a processor and can be either a back office billing system or an Internet Settlement Model. Also, the user can authorize the charges before the document is printed and the user's identify is authenticated by the system by submitting user credentials.
In a further aspect of the invention, the invention is a method for electronically recording transactions performed on at least one predetermined printer device, such that the printer device is coupled to an mobile access unit with transmits the content which is to be printed, comprising the steps of: transmitting a print request to the billing manager; retrieving billing policies for the printer device; indicating to a user the cost for a desired print request such that the cost is determined by associating a predetermined amount of token values with each particular operation performed by the printer; printing selected document at the predetermined printer device and generating an accounting of costs based on the usage of the predetermined printer device.
The method further comprises the step of authenticating the user's identity by transmitting user credentials to the billing manager. Also, the method illustrates wherein the billing manager associates a predetermined number of tokens for each corresponding event and tabulates the number of events that occurred during the printer operation and determining from that the token charge. The method further comprises the step of interfacing the printer device with a billing manager in such a way that allows the mobile access unit to connect with the billing manager. The method further comprises the step of sending the accounting information to a back office billing system which maintains accounting records of users and periodically issues an accounting of costs to the user. And the method further comprises the step of storing users account information in an account database and connecting the database to the billing manager.
Some of the advantages of the present invention include the user or owner of a printer device to charge for usage on their device and only be billed for their net usage. The present invention has the ability to allow individual printer devices to be configured with specific billing policies and bill users of the device according to those policies. The users are billed not only for printing documents but also finishing options such as binding, stapling and other functions. Also, the ease of the centralized control and configuration of billing parameters is a benefit. Those skilled in the art will appreciate these and other advantages and benefits of various embodiments of the invention upon reading the following detailed description of a preferred embodiment with reference to the below listed drawings.
The invention is described in greater detail hereinafter, by way of example only, through description of a preferred embodiment thereof and with reference to the accompanying drawings in which:
Referring now to the drawings and in particular
The system 2 provides for the ability to configure any printer device directly with billing policies and allow any mobile user to print to devices based on those billing polices. Examples of those polices can be: classifying a printer as free, charging per page, allowing any users within an access list to print for free, charging different prices based on the user, and specific charges for finishing options such as stapling, collating, binding, printing color documents, etc.
The operation of the system 2 will be discussed with regards to
The billing manager 4, manages the billing polices attributed to each printer device 12 and also contains higher level polices. For example, on policy may be to charge everyone in a given department a certain price. The billing manager 4 may also contain a system processor and a memory device (not shown). The billing manager 4 may be connected to a billing polices database 6. The billing polices database 6 may be configured to store site or location-specific billing polices. For example, the billing polices could be free or for-fee printing, billing fee per page for each type of printer, user access lists for each device and accounting location information. The billing policies database 6 can be configured for a specific department or a user basis for predetermined users. The billing manager 4 may also be connected to the printer device(s) 12. The printer device(s) 12 may be known printer units that are capable of color printing and other known printer characteristics. The printer device(s) 12 may have device-billing attributes stored locally in their processors. This allows device-specific attributes to be added to the device itself. The billing manager 4 stores these attributes and substitutes the new device-specific attributes for the previous attributes.
The billing system software 8 is coupled to the billing manager 4 by either a direct or wireless connection. This billing system software 8 is preferably a traditional back-end billing system that manages the billing transactions themselves. This could be a settlement service on the Internet or an Enterprise accounting system. These systems are well known in the art and will be discussed with more detail later. The billing system software 8 is connected to the accounts record database 10. The account records database 10 stores the billing data as a result of the printing transactions. Also, as will be discussed with regards to
The billing system software 8 allows for the configuration of any printer device 12 directly with billing polices and allows a user to access those devices based in accordance with the billing polices. The system includes a network of printer devices 12 electronically interconnected via a network (not shown). The network could consist of a business, plurality of business or devices in a public area, such an airport or library.
A typical scenario for billing a particular print job is illustrated in
Once the user has initiated contact with the printer device 12, as shown in block 110, the printer device 12 connects to the billing manager 4. Once the mobile access unit 14 establishes communication with the printer device 12, the printer device 12 connects to the network (not shown), allowing the user to communicate with the billing manager 4. Subsequently, the printer device 12 is connected to the billing manager 4, and the billing manager 4 prompts the user to input user credentials to authorize user access to the network as shown in block 120. User credentials can be credit card information, a digital signature, an account code, a digital certificate or user name or the like.
At block 130, the user transmits user credentials to the billing manager 4 from the mobile access unit 14. The billing manager 4 determines whether the received credentials correspond to the credentials stored in memory for this particular user as shown at block 3. If the credentials are different, then as shown in block, 210, the user is denied access to the system. If the transmitted credentials correspond, then the document to be printed or document reference is transmitted from the mobile access unit 14 to the billing manager 4. The billing manager 4 retrieves from its memory a list of all the available printer devices 12. The user then selects the printer device 12 to which the document is to be printed. The billing manager retrieves the billing polices for that printer, as shown in block 150. The billing polices are stored in the billing policies database 6.
The billing polices can be any payment mode or plan, such as whether the cost of printing is free or a specific cost per page or whether the printing is free for certain users. The billing polices are retrieved from the billing policies database 6 and stored at the billing manager 4. One of ordinary skill can easily recognize that this list is not exhaustive of the possible combinations of billing polices that can be implemented, but only an illustrative few. The polices are determined at the system initialization and stored in the database 6. If for example, a user or printer device 12 was new to system or the characteristics of a pre-existing user have changed, then a system administrator would input the new billing characteristics of the user or device into the initial setup unit 16, which could then update the billing policy database 6.
The billing manager 4 would determine whether there is a charge for printing requested by the user in block 160. If there is not, the document is sent to the printer. If there is, then the billing manager 4 transmits the computed charges to the user, as shown in block 160. The mobile access unit 14 receives the transmission from the billing manager 4 and displaying the printing fees, as shown in block 170. The billing manager 4 transmits the fee to the mobile access unit 14. Once the fees have been displayed to the user, the system prompts the user as to whether to accept the charges, as shown in block 170. If the charges are accepted, then the document is retrieved from the memory of the billing manager 4 or the document is retrieved from the location specified in the document reference and transmitted to the specified printer device 12, as shown in block 180. However, if the charges are not accepted, then the user is denied access (not shown). The charges themselves will be explained in further detail with regards to
In block 190, the billing manager 4 determines if there is billing required for the completed printing operation. If there is no billing required, this means the printing was performed for no cost and then the operation is concluded. If there is billing required, then the billing information is determined and transmitted to back office system software 8 as shown in block 200. For example, the billing manager 4 would determine that a specific user printed a document consisting of 4 sheets of paper at 10 cents each and send that information to the back office billing system software 8, which processes the information. As stated above, the back office billing system software 8 can be a settlement service on the Internet or an Enterprise accounting system. Both systems are well known in the art. The back office billing system software 8 reconciles the present transaction with the user's account and updates the user's account information in the account records database 10.
The system of a preferred embodiment uses tokens as an arbitrary measure of the usage of the printer devices. The tokens represent the costs of predetermined printing operations. In a preferred embodiment, the tokens have no monetary value. However, one of ordinary skill in the art can envision an embodiment of the invention in which the tokens are of a form of electronic currency.
The billing system transactions are shown in
The owner of the printer at which the user printed the slides and text (for example, the patent attorney, but also can be any individual, a building or a department) is then credited the token amount corresponding to a token fee as shown in block 320. The token fee can be the entire cost of printing or a percentage thereof. The fee is determined by the billing policies of the printer device. The owner of this printer is then credited in the account records database 14 by the back office billing system software 8.
The billing system allows a user to print documents remotely. The system preferably keeps track of the accounts of the users and resolves the billing accounts on a periodic basis. The system allows users to generate a negative token balance. A negative token balance means performing more printing services than allocated by system for a predetermined time. If that is the case, then the user may need to pay for the costs of the excess printing services. The operation of the periodic token billing system is illustrated in
The foregoing description of a preferred embodiment of the invention has been presented for purposes of illustration and description.
