Abstract
Restricting the printing of sensitive electronic documents. After the client downloads a document (e.g., by viewing the document in a web browser), the client intercepts a print command, pauses the print, and issues a print request to a server. From a server perspective, upon receiving the request, the server determines whether the document is print restricted. If not, the print operation is permitted to proceed. If so, the server responds negatively to the print request and alters the document so that, even if printed, sensitive information is not printed. In another embodiment, the server may restrict printing prior to downloading a document. For example, the server may make the document read-only, or replace the document with another printable document that does not contain sensitive content.
