Abstract: In a network having an initiator, a server, and an input/output (I/O) device remote from the initiator, the initiator transmits to the server a request containing the network location of data to be retrieved from an input device, such as a video camera, fax, or scanner, or output by an output device, such as a printer. Output requests are placed in a queue and scheduled for completion. When an output device is ready, the server retrieves the data from a network storage location different from the queue and transmits the data to the printer or output device for action. When an input device is ready, the server retrieves the data from the input device and transmits it to a network location based on the request. The server can also provide the initiator with status information about the request and the input or output device.

Abstract: In a network having an input device, such as a scanner, camera, or fax, and a destination device, the input device initiates transmission of input data to a destination device. The input device sends a request to the destination device notifying it of input data that is ready to be transmitted. If the destination device wants to accept the request, when the destination device is ready, the destination device gets, or “pulls” the data from the input device over the network. The input device can request and receive status information from the destination device. The destination device can also request and receive status information from the input device.

Abstract: A printer driver comprising a separate page driver for analyzing print data and storing analysis data into a journal file, a journal file processor for retrieving the analysis data from the journal file, and a separate render driver for variably processing the print data depending on the type of stored analysis information, rendering the variably processed print data into picture elements having a reduced pixel depth, storing the picture elements into a band buffer, and providing the picture elements to a printer to produce high-quality printed images.

Abstract: A split printer driver comprising a separate page driver for optimizing and storing print data into a journal file, a journal file processor for retrieving the optimized print data from the journal file, and a separate render driver for receiving the optimized print data from the journal file processor, processing the optimized print data using an image processor, rendering the optimized print data into picture elements, and providing the picture elements to a printer to produce high-quality printed images.

Abstract: A system renders a print image while enabling reduction of the size of band memory. The printer driver includes a rendering driver comprising a driver interface, a drawing engine, an image and color library, band buffers and a color converter. The driver interface receives image data and drawing commands and transmits them to the drawing engine. The drawing engine divides the page into a series of bands, applies each drawing command for a band and renders the portion of an object in the band to a temporary buffer. To render an object, the drawing engine applies enhancement functions such as color biasing, image resolution enhancements, inverse dot gain transforms, etc. on the object and then applies a dithering function to convert intended color or gray-scale values of objects in the band to bi-level planar pixel matrices. By applying the dithering function before storing each band in band buffer memory, the size of the requisite band buffer memory is significantly reduced.

Abstract: A system calibrates a computer print image. A page driver receives an image having image properties, such as color scheme, image resolutions, contrast, etc., and sends it to a journal file for storage. A user interface enables selection of a property of the image. A journal file processor generates specific values based on a selected range of values for controlling the characteristics of the selected property. A rendering driver renders a modified version of the image for each generated value, and sends the modified versions to the printer. The user interface enables the selection of a preferred image from the rendered modified images. The journal file processor sends the values of the selected image to the driver settings file for storage.
