Method and system for detection and avoidance of duplicate print jobs with pre-imaging technique using document stacker and central system

A non-transitory computer readable medium (CRM) storing computer program code executed by a computer processor that performs a method for detection and avoidance of printing print jobs previously printed, the method comprising:

• storing one or more digital copies of print jobs in a central storage system;
• storing one or more physical copies of the one or more digital copies of the print jobs in a document stacker;
• receiving a print job on a printer;
• sending a request from the printer to the central storage system to determine if a physical copy of the print job is in the document stacker;
• and
• when the print job is in the document stacker sending a code from the central storage system for retrieval of a physical copy of the print job from the document stacker.

A system for detection and avoidance of printing print jobs previously printed, the system comprising:

• a server having a memory and a processor, the processor configured to:
• store one or more digital copies of print jobs;
• a document stacker configured to:
• scan one or more physical copies of the one or more digital copies of the print jobs;
• send the one or more digital copies of the print jobs to the central storage system from the document stacker;
• store the one or more physical copies scanned by the document stacker in trays;
• and
• shred the physical copies of the one or more digital copies of print jobs stored in the document stacker upon an expiration of a predetermined date assigned to the print jobs;
• and
• a printer configured to:
• receive a print job;
• sending a request from the printer to the server to determine if a physical copy of the print job is in the document stacker;
• and
• when the print job is in the document stacker receiving a code from the server for retrieval of a physical copy of the print job from the document stacker.
