  • Non-format violating PDL guessing technique to determine the page description language in which a print job is written
    Patent number: 6525831
    Abstract: 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.
