Look at the extended page-label feature of the alternate pstops filter
(to be found via
the links on the CUPS home page).
I recently posted I'm thinking of inserting code to make certain job
attributes and
environment variables available to the PostScript code - so you could
patch a bar code
onto the first page as a page label, for instance.
