I need a way to automatically place a dynamic stamp onto a document when it is printed to the default printer. The dynamic stamp would include the current date and time of printing (the dynamic aspect) and also include some static text, something along the lines of "This document expires 8 hours after the date and time listed." Customizable text here would be sweet.
This needs to work with any printed document type, be it .TXT, .PDF or whatever, and this stamp must appear on every printed page.
All of the programs I have found seem to allow dynamic stamping but require the document be stamped and then saved prior to being printed. In other words, sure I can place a dynamic date and time stamp on a batch of .PDF's and save them in one sitting, but then they will have the date and time on them from the stamping session instead of an "on the fly" stamp with the current date and time at the moment of printing, as is needed.
Thank you for your consideration, and any input would be greatly appreciated.
