Claim Text:
1. A computer-implemented method for classifying a plurality of print jobs to be printed by one or more printing devices the method comprising: a) acquiring non-obfuscated PDL versions of the plurality of print jobs destined for the one or more printing devices, the PDL versions of the print jobs including one or more of non-obfuscated textual content and image content; b) differential processing the non-obfuscated PDL versions of the print jobs to generate obfuscated versions of the print jobs, the differential processing obfuscating the textual content with a first differential process and obfuscating one or more portions of the image content with a second differential process, the first and second differential processes obfuscating one or more portions of the textual content and image content, respectively, such that the textual content and image content is illegible while preserving an overall shape and location of the textual content and image content; c) manually labeling one or more of the obfuscated versions of the plurality of print jobs according to one or more of a plurality of document type categories, the categories associated with the overall shape and location of the obfuscated textual content and the obfuscated image content; d) training a classifier using some or all of the manually labeled obfuscated versions of the plurality of print jobs; and e) accessing the trained classifier to classify one or more of the obfuscated versions of the plurality of print jobs or classify one or more of the non-obfuscated PDL versions of the plurality of print jobs, each print job classified as one or more of the plurality of document type categories.
