Embodiments herein include a method, service, apparatus, etc., that sets at least one integrated circuit board (that has programmable elements) to a programming state. When such programmable elements are set to the programming state, they are capable of being changed. Once the programmable elements are set to be changed, at least one printed sheet is scanned. The scanning can be preformed using any scanner that is operatively connected to the integrated circuit board through, for example, a processor. Again, the printed data (e.g., the barcodes or glyphs or other computer-only readable markings) on the printed sheet comprises the reprogramming data. The processor reads the barcodes or glyphs from the bitmap generated by the scanner, and executes the reprogramming data to change the logical instructions and data maintained within the programmable elements.

What is provided are a system and method for print/copy job environments utilizing a page description language (PDL). In one embodiment, an input PDL stream describing embedded objects in a job is received and parsed. Reusable document components (RDCs) are identified. A determination is made as to how many placements are in the PDL for each identified RDC. If no RDCs are placed more than once, caching is disabled. If it is not efficient to split the PDL stream into smaller tasks, page parallel rip (PPR) is disabled. The embedded objects are analyzed to determine a number of PPRs for the job based on system resources. A raster image processing (RIP) time is projected for each path in the job based on the determined number of placements and the determined number of PPRs. A job processing path is prescribed for the job based on the most efficient projected RIP time.

Page parallel RIP and cache tuning in print/copy job environment utilizing page description languages

This is a system for maximizing the use of colors in cartridges of a color marking system. By controlling the amounts of each color dispensed where the least abundant color is conserved, the life of the cartridge is extended. A sensor tells the system what amounts of each colors remain in the system, and a dispenser controller uses and dispenses the most abundant colors first, preserving the least abundant color necessary to achieve a desired colored marking. GCR (gray component replacement) is used as the fundamental scheme to control the colorants. GCR-like scheme is used for interchanging a particular non-traditional colorant and multiple conventional colorants that make such color.

A method of displaying information within a three-dimensional workspace on a computer display includes partitioning the workspace into a plurality of layers, where each layer corresponds to a display depth relative to a user. At least one substantially opaque container object is displayed at a first display depth. The user is provided with a pointer operative to select objects within the three-dimensional workspace at a plurality of display depths. In response to the user selecting a container object, the opacity level of the selected container object is reduced in order to reveal at least one content object contained therein. The at least one content object contained within the selected container object is displayed at a deeper display depth relative to the first display depth. By combining three-dimensional depth cues with opacity level adjustment the present invention provides a visually pleasing computer workspace with enhanced depth perception and organization features.
