Under Print: Watermark, in the Options dialog box, you can configure an optional watermark that can be added to printed documents. For instance, you might want to indicate that documents are company owned or that they should not be redistributed. You could use a watermark that said "CompanyName" or "Do Not Copy."
Note: If you have a group watermark assigned to you, or if a document already has a watermark due to a tag applied to it, you will not be able to apply an optional watermark to that document.
Note: You can use tokens in optional watermarks. For instance, you could use the %(Time) token to keep track of the time you printed the document.
