I have a client with employees that send documents to the network printer and then "forget" to pick them up timely, so they get lost in a big mess of paper. What I'd like to do is to automatically have all printed documents include some identifier (like the name of the person printing) in the footer of the document so each page that comes out is labeled with the name of the person printing it.

My thought was to setup a Samba print server for the network printer, and have it somehow modify jobs as they come into the queue, adding the network user's name to the bottom right corner. However, I'm not even sure this is really possible, because I know the print job has already been "encoded" using the driver installed on the client's Windows machine.

Ideas?
