[0024] The present invention relates to a system and method for monitoring printer- related data on USB cables and relaying the data to a printer reporting system via a base station, wherein the monitoring is performed using hardware affixed to a USB cable. The various components of the present invention, and the manner in which they interrelate, are described in greater detail hereinafter,

[0025] The computer-implemented method and system may include, but are not limited to, the following steps. If will be appreciated by one skilled in the art that the order of steps presented herein may be performed in a different order. It will also be appreciated by one skilled in the art that the method and system described herein for monitoring and reporting printer-related data may include all, some, or none of the steps described herein.

[0026] Initially with reference to FIG. 1 , the associated system includes placing a device along a USB line between a personal computer and a non-networked printer. The device may include both male and female USB connectors for in-line connectivity. In one embodiment of the present invention the device is a USB-compatible device capable of transmitting radio frequency bandwidth outside of an existing computer network. The device passively monitors the USB line to defect printer actions, and reports data relating to printer actions to a base station via a mesh network. The data is reported to the base station via the radio frequency bandwidth. Data relating to printer actions may include, but is not limited to, the number of pages printed, color, ink or toner density, and other data. In one embodiment of the present invention, the system gathers data from outside of an existing network. The base station subsequently aggregates the data and uploads the data to a server over the internet or other network. In an alternative embodiment of the present invention, the USB device connects directly to the internet via radio frequency bandwidth, WiFi, cellular radio, Bluetooth, or other known communication technology and uploads the data to a server, thereby eliminating the need for a base station. The system does not require the installation of software on an associated computer. Further, the system does not require user-specific configuration because it is supplied pre-configured to monitor print jobs and printer- related data.

[0027] With continued reference to FIG 1 ., and now with reference to FIG. 2, the USB device may include a field programmable gate array (FPGA) and a microcontroller. The FPGA device, with its embedded content monitoring system for monitoring printer- related data, monitors traffic over a USB cable by looking directly for information that a printer has printed a page. This monitoring may be performed by searching for keywords in the data traffic indicating that a printer has printed a page. The device then shares the information via radio to a local base station or patrol device. More particularly, the device uses a USB PHY to synchronize the retrieval of data transfer from the USB line and performs low-level validation of the data, converting from serial data to an 8-bit bus. The data is then queued in a First In First Out (FIFO) within the FPGA. The FPGA may be equipped to perform string searches on the incoming data and/or provide the full bandwidth data to the microcontroller for searching and/or manipulation within the microcontroller. Upon notification from the FPGA, the microcontroller retrieves data from the FIFO and processes it. The processed data is then sent to the base station, or patrol device, via a mesh radio network that was previously established.

[0028] In one embodiment of the invention, and with continued reference to FIG. 2, the system and method include 1 ) capturing passing data with the USB device; 2) validating the data with a USB PHY and then synchronizing the data transfer; 3) converting the data from serial to 8-bit data with the FPGA; 4) queuing the data in queue FIFO; 5) searching the data for particular string sets relating to printing; and 6) receiving and packaging the data at the microcontroller to send it to the base station via RF.

[0029] With reference to FIG. 3, the associated system and method for monitoring and reporting printer-related data allows for the remote update of its application code, or firmware, by initializing the USB stack after power up, initializing its radio software stack, and checking with the base station to determine whether a firmware update exists. If a firmware update exists, the system updates the firmware. Once an update is complete or the device determines that an update is not required, it begins monitoring the USB data. Once a print event is detected, the device checks its non-volatile memory for previous print events that were detected but not reported, and verifies that radio communication exists with the base station. If radio communication exists, the device reports the print event details to the base station and flags the event as reported. If appropriately flagged, the unit then removes the print event details from the non-volatile memory and returns to the monitoring state. This entire process is completed without the need for the device to enumerate on the host computer. [0030] it will be understood by those of skill In the art that flowcharts and block diagrams herein described may illustrate architecture, algorithms, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments. Therefore, it will be understood that each block in the flowchart or block diagram may represent a module, segment, or portion of code, which comprises one or more executable computer program instructions for implementing the specified logical function or functions. Further, some implementations may include the functions in the blocks occurring out of the order as herein presented. By way of non-limiting example, two blocks shown in succession may be executed substantially concurrently, or the blocks may at times be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and flowcharts, and combinations of blocks in the block diagram and flowchart illustrations, may be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer program instructions.

[0031] The system includes one or more processing devices, which may be any computer processing unit, and could be a single central processing unit, or a number of processing units configured to operate either in sequence or in parallel. The processing device can be configured to execute software processes which implement the steps disclosed herein. The system may also include a memory capable of storing the steps necessary for a processing device to implement the steps disclosed herein. This memory could be in the form of memory resident within the processing device or in the form of standalone memory coupled to the processing unit via a communication path, such as a bus or a network.

[0032] Although this disclosure has been described in terms of certain embodiments and generally associated methods, alterations and permutations of these embodiments and methods will be apparent to those skilled in the art. Accordingly, the above description of example embodiments does not constrain this disclosure. Other changes, substitutions, and alterations are also possible without departing from the spirit and scope of this disclosure.
