ABSTRACT:
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.
