Abstract: Systems and methods for a device connected to a private network to efficiently retrieve a software/firmware update. The device may retrieve an update scheme that defines an external Uniform Resource Identifier (URI) for a resource external to the private network and a primary URI for a primary resource connected to the private network. The device may compare own Internet Protocol address and the primary URI to determine whether or not the device is the primary resource. When the device is the primary resource, the device may retrieve the software/firmware update from the external URI.

Abstract: System, apparatus, and methods for authenticating a device for access to a server. The method includes receiving a set of device-specific attributes from the device as a part of a device registration process, storing the set of device-specific attributes in a device attribute storage, and receiving a request to perform an operation using the device and involving the server. The method further includes transmitting a set of device-specific challenge questions derived from the set of device-specific attributes to the device, receiving responses to the set of device-specific challenge questions from the device, confirming that the responses each conform to the set of device-specific attributes, and enabling the operation involving the server.

Abstract: There is disclosed a method of, mobile device for and apparatus for using a mobile device to actuate a multifunction peripheral device using near field communication. The mobile device includes a user interface for receiving a selection of an electronic document and instructions regarding a selected document processing operation to be performed by the multifunction peripheral and for receiving a selection of an electronic address to which the electronic document is to be directed by the multifunction peripheral.

Abstract: The subject application is directed to a system and method for operation of document processing devices via portable data devices. A wireless data connection is established between a document processing device including a processor and associated data storage and an associated mobile data device. A remote installation of a software interface for the document processing device is initiated on the mobile data device via the wireless data connection. A multicast probe is received via the wireless data connection from the mobile data device initiated in accordance with operation of the software interface after installation. The mobile data device is registered with the document processing device in accordance with a response to the multicast probe. Control data generated by the software interface operable to commence at least one document processing operation on the document processing device is received from the mobile data device via the wireless data connection.

Abstract: The subject application is directed to a system and method for securing remote administrative access to a processing device. Incoming data packets, including source data, destination data, and a data portion for administrative control of a processing device are received at a designated port associated with administrative control. Binary mask data defining an address space from which control is acceptable is then received. Binary reference address data representing an address with an address range within the address space is received. A first binary value is generated via a comparison of the reference data and the mask data. A second binary value is generated via a comparison of an incoming data packet and the mask data. The acceptability of the packet is determined based on comparing the first value with the second value. Processing of received administrative control by the processing device is then selectively commenced based on the value comparison.

Abstract: A system and method for automatically resizing electronic documents based upon the original document page settings and the region of the outputting document rendering device. An electronic document is first received for output by an associated document rendering device. After receipt of the electronic document, the document rendering device retrieves its regional data. The regional data is used to determine the regional paper sizes available for outputting documents. Based on the retrieved regional data and the original output size of the electronic document, a determination is made as to the appropriate available output paper size. The electronic document is then resized, corresponding available output paper size, and rendered, without requiring user intervention.

Abstract: A method is disclosed including the steps of submitting a print job to a network printer and identifying a specific printer controller governing the print job. The method further includes loading a set of identifiers respective to a specific printer controller and selecting from the set a respective identifier corresponding to the type of print job employed on the specific printer controller. The selected identifier is used to issue the predetermined type of notification from the controller.

Abstract: A DC/AC converter circuit structure for driving a plurality of cold cathode fluorescent lamps is described. A common-mode choke is used between the cold cathode fluorescent lamps. The common-mode choke balances the currents respectively flowing through the cold cathode fluorescent lamps.

Abstract: A printer controller is disclosed which includes one or more non-volatile memory elements for storing print/fax/scan data and printer controller system parameters. The non-volatile memory elements can include flash memory PCMCIA cards. A non-volatile storage medium is also provided for retaining an operating system, wherein the printer controller is bootable from the non-volatile storage medium. The non-volatile storage medium is preferably a CD-ROM or other removable type data disc.

Abstract: A system update protocol. A software update is packed into a packed file, which packed file includes a unique signature. The packed file is uploaded from a trusted client computer to the network printer. The integrity of the packed file is automatically checked on the network printer by performing a checksum and signature comparison to ensure the packed file is transmitted correctly. The packed file is resent when the packed file is determined to be corrupt. The packed file is unpacked into a predetermined directory structure of unpacked files. The client computer then signals the network printer cause installation of the software update on the network printer.

Abstract: The present invention is directed to a system and method for filtering packets for a printing device. An IP address filter resides within an SNMP agent and acts to filter incoming SNMP packets, thereby restricting the visibility of the printing device to a small select group of users. An administrator determines the range of IP addresses to either allow access or reject. The filter comprises a reference IP address, within the range of administrator selected addresses and assigns an action corresponding to the selected addresses. The action may be either allowing the SNMP packet to be processed, or rejecting the SNMP packet and dropping the packet without replying to the sending address. To determine if the incoming packet source address matches the reference address, a 32-bit mask is also included within the filter.
