Approach for printing policy-enabled electronic documents using locked printing and a shared memory data structure

摘要

According to approach for printing policy-enabled electronic documents, when a locked print module determines that an electronic document contained in the PDF print data is a policy-enabled electronic document, the locked print module causes the PDF print data to be stored on the printing device and not immediately processed for printing. A PDF-to-postscript conversion module generates and stores in a common data structure in the shared memory a request for security data for the PDF print data. A policy client module retrieves the request from the common data structure in the shared memory, obtains security data for the PDF print data from a policy server, and stores the security data in the common data structure in the shared memory. The PDF-to-postscript conversion module uses the security data to decrypt the PDF print data and then converts the decrypted PDF print data into postscript data for printing by the printing device.
