Help needed desperately on event logs..

Is there any way of finding out the contents of print outs from a user id.. Today some confidential information has been printed by an unidentified user and was sent to an outside company.. While i have the details of only the file names printed by users stored in my event logs, I dont think this is of much use as an intelligent user can always type some info in an existing document and then print it and delete it.
So i want to know if we can see the contents of documents printed along with user id so that we can catch the culprit. Pls help,
