Patent Application
20140085658
The methods and systems disclosed herein are related to adding functions to printers. Presently, adding a new function or capability to a printer can be expensive for an original equipment manufacturer (OEM). An incremental capability brings an incremental bill of materials (BOM) cost and higher retail prices. The cost of adding multiple functions can be difficult to justify when only around 20% of the functions in printers are used by customers.
According to embodiments of the subject matter disclosed in this application, an upgrade module, also referred to herein as a Computer on an Upgrade Stick (COUS). offers a method of adding a new printer function to a printer without increasing the bill of materials cost to the printer itself. The COUS may be an internal module installed into a printer by a manufacturer, or an external plug-in module that customers can purchase separately. The COUS may be compatible with any existing or future printing device, from a simple home desktop printer to an advanced multi-function printer. The COUS may contain a central processing unit (CPU), memory, software, and any peripherals needed to perform its function. The COUS enables the printer manufacturer to provide lower cost printers, while enabling users to purchase specific upgrade capabilities that they are interested in. No changes to the printer's embedded software or hardware are necessary, as the COUS can be configured to couple with the printer through a communication port on the printer. For example, the COUS can use an existing, industry-standard USB port on the printer, and can communicate over this channel using industry standard protocols such as Printer Control Language (PCL) or Postscript.
Any number of new printer functions may be added to the printer through the COUS. In one embodiment, the COUS can determine the location of itself and the printer, and transmit the location data to one or more computers for location services. In another embodiment, the COUS can act as an interface between the printer and a mobile device, thus, enabling the printer to communicate with the mobile device. The COUS may enable a secure communication channel and protocol stack, which are capabilities that may not be native to the printer. In another embodiment, the COUS can recognize a user identification tag from a remote point, and grant the associated user permission to print. Identification of the user can also enable the printer to print with user specific features enabled. It is to be understood that the embodiments illustrated in the following figures do not represent all of the possible new printer functions that the COUS is able to add.
The printer 102 may be connected to a COUS 106, which can provide the printer 102 with one or more additional functions. The variety of functions that may be added may include, but are not limited to, location detection, mobile device interface, user identification, security, wireless communication, memory storage, and additional communication protocols. The COUS 106 may also be connected to a computing device 104, which can allow a user to access and control the functions featured on the COUS 106. The COUS 106 may also be connected to a network or server.
The connector 206 may interact with the COUS 106. The COUS 106 may include a base computer subsystem 220 that can serve as the COUS's central processor and function specific software 222 that is necessary to perform the COUS's additive printer functions. The COUS 106 may also contain additional modules or periphery features that can aid the COUS's new printer functions. In one embodiment, the COUS may contain a storage unit 224, a wireless communicator 226, and a cryptography engine 228. The wireless communicator 226 allows the COUS 106 to exchange information with a mobile device without a direct connection such as a wire or cable. The mobile device may be a smartphone, a tablet computer, or any device that is not configured to directly connect with the printer 202. The cryptography engine 228 allows the COUS 106 to encode outgoing information being transmitted from the COUS 106 to other devices, or decode incoming information being received by the COUS 106 from other devices.
The printer 302 may contain a connector 308, a controller 310, and a print engine 312. The COUS 304, which is configured to interact with the printer 302 through the connector 308, may contain a processor 314 and location software 316. The processor 314 controls the operations of the COUS 304. The location software 316 contains coding that can determine the printer's position, either globally or within a local environment such as a building layout. The COUS 304 can transmit the location information to the server 306. The location information may be transmitted to the server 306 through a network 318, which may be wired or wireless. The location information is received by the server 306, which may also be connected to multiple printers 302, each with a COUS 304 configured for location detection attached. The server 306 may store the location information of each printer 302 in a database, so that the location information can be readily accessed by computers.
The printer 402 may contain a connector 408, a controller 410, and a print engine 412. The COUS 404, which is configured to interact with the printer 402 through the connector 408, may contain a processor 414 and a first wireless communicator 416. The processor 414 controls the operations of the COUS 404. The first wireless communicator 416 may be configured to interact with a second wireless communicator in the mobile device 406. The mobile device 406 may be a smart phone, a tablet computer, or any other electronic computing device. The first wireless communicator 416 can detect when the mobile device is within a certain range. Upon detection, the mobile device 406 may establish a wireless connection with the COUS 404. Once connected, the mobile device 406 can exchange information with the COUS 404 through their respective wireless communicators. In one embodiment, the mobile device 404 can send documents to the COUS 404 to be printed by the printer 402.
The printer 502 may contain a connector 508, a controller 510, and a print engine 512. The COUS 504, which is configured to interact with the printer 502 through the connector 508, may contain a processor 514, user ID software 516, a database 518, and an ID reader 520. In some embodiments, the COUS 504 can also be connected to a fingerprint reader 522. The processor 514 controls the operations of the COUS 504.
The COUS 504 is configured to scan and recognize an ID tag, either through its own ID scanner 520 or through the remote ID scanner 506. The identification information is received by the COUS transmitter 520. The user ID software 516 processes the identification information by comparing the identification information with a list of authorized users in the database 518. If the identification information does indeed correspond with the list of identifications, then the ID tag 526 is approved. The COUS can also scan and recognize a fingerprint using the fingerprint reader 522, and compare the fingerprint with a list of authorized user fingerprints in the database 518
At block 604, the user can send a request to the COUS to determine the location of the printer. The request can be sent from a computer or device that may be directly connected to the COUS, or connected communicatively through a server. The COUS can determine the printer's position, either globally or within a local environment such as a building layout. The COUS can transmit the printer's location to the computer or the server.
At block 606, the user can store information pertaining to the location of the printer in a database. The database may be associated with the computer, or it may be associated with the server. Storing the location information in the database can enable users to look up the printer's location.
At block 704, the user can establish a connection between a first wireless communicator in the COUS and a second wireless communicator in a mobile device. The connection can be established by moving the mobile device within range of the COUS, where the first wireless communicator automatically detects the presence of the second wireless communicator. The connection can also be established manually, in which the user sends a request from the mobile device to connect to the COUS through the first and second wireless communicators.
At block 706, the user can send a print job from the mobile device to the COUS. The print job may be any document or image stored on the mobile device. The print job may be sent through any means of wireless communication. Examples of wireless communication may include WiFi, Bluetooth, and nearfield communication. The COUS forwards the print job to the printer through the communications port on the printer.
At block 804, the user can scan a user identification tag using an ID scanner associated with the COUS. The user identification tag may be a barcode, a computer-readable serial number, a radio-frequency identification (RFID) tag, a fingerprint, or any other user-unique form of user identification. The ID scanner may be a component on the COUS itself or an external device connected to the COUS. The act of scanning the user identification sends scanned identification information pertaining to the user identification tag to the COUS, where the scanned identification information is compared to a list of authorized users contained in a database. The list of authorized users can contain identification information associated with each authorized user. The COUS determines whether or not the scanned identification information is associated with one of the authorized users in the list of authorized users.
At block 806, the user can send a print job to the printer. The print job can be processed if the COUS determines that the scanned identification information is associated with one of the authorized users contained in the list of authorized users. The COUS forwards the print job to the printer through the communications port on the printer.
