Abstract
Systems and methods presented herein provide for the processing of PostScript print jobs that are not DSC compliant. A single stream of a PostScript data is processed and divided into multiple streams (e.g., page objects), each comprising data operable to render an individual page. In one embodiment, a method includes receiving the PostScript data stream and identifying object tokens in the PostScript data stream. An object token is operable to generate a PostScript object or execute a PostScript operation. A portion of the object tokens may be operable to define page boundaries in the PostScript data stream. The method also includes analyzing the object tokens to parse the object tokens into a plurality of page objects, separating the page objects into a plurality of data paths, and parallel processing the page objects through the data paths to rasterize the PostScript data stream on a page by page basis.
