METHOD AND SYSTEM FOR SECURELY GENERATING DOCUMENT VERIFICATION RECORDS
Methods for providing security in a document printing process are disclosed. In various embodiments, when a system comprising a print device receives source document files, then before printing it may ensure that the system satisfies various security conditions before it will print verification document sheets based on the source document files. For example, the system may require that data from all prior print jobs be cleared from the memory. The system also may require that the print device be restricted from external communications, browser application usage, or both. After printing all verification document sheets for all of the source electronic document files, the system may restrict the print device from processing any future print jobs until all data associated with the source electronic document files and the verification document sheets have been removed from the print device.
