Disclosed herein is a production planning processor comprising an admissions control module in communication with a queue management module, the admissions control module calculating a proposed profit for expedited handling of a new print job, the queue management module determining a revised print job queue based upon data received from the admissions control module. A corresponding method of processing print jobs is also disclosed, along with a system and a method for determining the profitability of accommodating a rush print job.

Processor, system and method for accommodating high priority print jobs

A printing system produces prints from a print job written in one of a plurality of page description languages with the print job assuming the form of a print job stream. The printing system includes a page description language guesser having a plurality of page description language analyzing units for sampling the print job stream, each analyzing unit outputting an information signal which provides information regarding the print job stream. The PDL guesser, which receives the information signals, processes the information signals and outputs a filtered signal which indicates the page description language in which the print job is written. The page description language (PDL) analyzing unit verifies that in the data sample all command operator strings, their associated parameters and interspersed data are valid for a particular PDL or Image Format.
