ABSTRACT:
A method and system for identifying print jobs that are repeats of a previously completed job utilizing an object level hash table. Received print jobs can be parsed into meaningful classes of objects and a table of hash values can be computed for objects in each class and for each print job. A synopsis comprising the table of hash values can be retained in a database along with the job specific settings. A newly encountered job can be then declared as a repeat of a previous job based on the hashes for the new job that match the hash values for the previous job stored in the database. The classes of objects are readily determinable in common document formats used for print job submission, such as PDF.
