Distinguishable copies of invoice

Want to print three copies of the same invoice and distinguish each by a watermark, different background shading, or a different border. Is there a way to use a particular watermark(e.g. “FILE COPY”) via PCL and/or PJL, for example? A shaded background would be acceptable. This would be done on a dedicated laserjet printer that only prints invoices. Don’t know if I have to print the same invoice three times or can programmatically make changes via a macro to have each copy printe with the changes desired.
