    摘要: A printer produces an improved pixel image representation of encoded image data when sub-image portions are combined into larger image portions. The printer receives encoded image data as a data stream of sub-image segments and stores the sub-image segments. Each sub-image segment includes associated graphics state information which defines at least some image attributes of the sub-image segment. When each new sub-image segment is completely received, it is placed on a closed image list. Upon such listing, the printer's processor compares the graphics state information and boundary data for the now complete sub-image segment with at least one other listed sub-image segment in the closed list. The processor combines the new sub-image segment with the other sub-image segment if both a matching graphics state and matching boundary data are found. An image processor within the printer then subjects the combined sub-image segments to spatial processing as a unitary image.

    摘要: A printing system for printing documents that includes a recurring image. The printing system includes a computer connected to a printer over a communication link. The computer generates a named sequence to represent the recurring image and a parameter. The parameter value provides the printer with information that can be used to optimize the processing and printing of the named sequence.

    摘要: A system for reducing memory resources required to process a print job having common page print data. Reduction of memory resources is accomplished by first analyzing pages from an application for common page aspects and unique page aspects. The common page aspects are then converted to common page print data and the unique page aspects are converted to unique page print data. The common page print data is identified in a manner allowing for an optimized form of the common page print data to be created. An optimized form of the common page print data is then created and stored. The common page print data is merged with the unique page print data in an appropriate manner. Each page is then printed. The invention has particular benefits for presentation applications using the same background for each page in a set. Other applications can also benefit.
