Inserting a graphical symbol into a print stream for a document file that does not include the graphical symbol

摘要

A printed document manager manages printed documents and is separate from Document Management Systems (DMSs) that manage electronic soft copy documents. One or more DMSs are registered with a postmark server. A client computing device executes a postmark client, detects a print event for a specified document, and queries a postmark server to determine whether the print event for the specified document should include a graphical postmark. In response, the postmark server queries one or more of the registered DMSs to determine whether the specified document matches a document in any of the repositories of the registered DMS(s). When the specified document to be printed matches a document in a registered DMS, the postmark server authorizes the postmark client to add the graphical postmark in a print stream corresponding to the print event for the specified document.
