Abstract: Some of the embodiments of the present disclosure provide method comprising receiving a request at a device for a device driver associated with the device, the request for the device driver being received at the device through a network, the device having a network configuration in the network; and transmitting the device driver from the device in response to the request, including transmitting the network configuration of the device.

Abstract: A system including a communication interface, a memory, and a processor. The communication interface is configured to receive data. The memory is divided into a first retention region and a second retention region, wherein the first retention region is configured to store data for a first predetermined period of time, and the second retention region is configured to store data for a second predetermined period of time. The processor is configured to i) initially store, within the first retention region of the memory, the data that is received, and ii) in response to the data that is received having been stored in the first retention region of the memory for a time limit that exceeds the first predetermined period of time, transfer the data that is received from the first retention region of the memory to the second retention region of the memory.

Abstract: A digital circuit generates very precise clock frequencies for applications that can tolerate a small degree of jitter but require exact long term frequencies, e.g. a video clock for a laser printer. Some subpixel jitter is acceptable, but the overall pixel rate remains exact and consistent. In some applications, the jitter may be desirable to smear the EMI spectrum. For example, if the high frequency input clock is modulated, the edges of the video clock will also be modulated yet remain within the jitter and frequency specification.

Abstract: A wireless printer system includes a wireless transceiver that generates a baseband signal based on a received radio frequency signal. A first system on a chip communicates with the wireless transceiver and includes a system on a chip. The system on a chip includes a wireless interface module and an imaging module. The wireless interface module processes the baseband signal to generate a print data signal via a wireless interface software. The imaging module processes the print data signal to generate a print image signal via an imaging software.

Abstract: A lid structure, apparatus and method for displaying graphical information uses beams of coherent light that are emitted in a scanning manner to project the beams of coherent light onto a display surface to form the graphical information on the display surface.

Abstract: In accordance with the invention, it has been determined that the bandwidth, guaranteed periodic delivery and error correction characteristics of a USB High-Speed Interrupt OUT pipe of the USB 2.0 standard enable the Interrupt OUT pipe to be used to transfer print data from the host computer to the printer. By using the Interrupt OUT pipe for this purpose, it is no longer necessary to store an entire rasterized page in the formatter memory of the printer before commencing printing of the page. Consequently, the size of the formatter memory device can be relatively small compared to the size of the formatter memory device that is currently used to store an entire rasterized page. Alternatively, the same size memory device as that currently used to store an entire rasterized page may be used to enable higher resolution pages to be printed.

Abstract: A demonstration system for a peripheral such as a printer connects an external, non-volatile memory to the printer in place of the host computer. One such peripheral uses a peripheral cable containing a controller or formatter that includes a computer interface for communications with the host computer and an interface for memory accesses. The peripheral cable connects to the computer interface for communications with the host computer. The demonstration system employs a controller or formatter of the same type as used in the peripheral cable and-connects the interface for reading from the external memory. The controller can load both demonstration code and demonstration data from the external memory and direct the peripheral to perform a demonstration.

Abstract: A printer device includes a printer engine controller in communication with a print mechanism and a printer formatter. The printer formatter includes a quad flat pack (QFP) package having an application specific integrated circuit (ASIC) mounted and a memory device mounted therein. The printer device further includes a substrate having the QFP package and the printer engine controller mounted thereon.

Abstract: A digital circuit generates very precise varying clock frequencies for applications that can tolerate a small degree of jitter but require exact longer term frequencies, e.g. a video clock for a laser printer. Some subpixel jitter is acceptable, but the overall pixel rate remains exact and consistent. In some applications, the jitter may be desirable to smear the EMI spectrum. For example, if the high frequency input clock is modulated, the edges of the video clock will also be modulated yet remain within the jitter and frequency specification.

Abstract: A video controller includes a video block that connects to the print control engine and one laser driver. The video block includes a direct memory access (DMA) block, a video processor, a waveform generator including pattern and multiple pulse mode modulation, a frequency synthesizer, configuration registers, and a data bus. The frequency synthesizer connects to the waveform generator. The configuration registers connect to the DMA block, video processor and the waveform generator. The data bus, operative to carry bus control signals, connects the DMA block, video processor, waveform generator, and the configuration registers.

Abstract: The invention provides an architecture and method for implementing a programmable I/O interface. The primary function provides a generic reconfigurable interface for serial communications between a laser printer controller and the print mechanism. The design also supports vertical page synchronization (top of page detection).
