I have an RFP where one of the RM requirements is to print an Expiry Date on
the bottom of every hardcopy of a document when it is printed. The Expiry
Date is to be calculated from the Current Date + 7 Days. I can easily
imagine how to do this for Word documents (using a custom Word template) but
do you know of a way to do this, for example, for PDF documents?

For example, I'm wondering if there is a Printer on the market that can be
pre-programmed each morning to print a watermark on every document printed
...regardless of the application or document that is printed on the printer.
