Generate a random then sequential number for each printed copy

Prefacing with the fact that I know next to nothing about javascript programming, but I'm curious if what we're trying to accomplish is possible with it.

I have a single page PDF on a file server that is printed repeatedly throughout the day at varying quantities (usually less than 100 copies).  I know I can inset Bates numbering, but that seems to only number the page itself, not any copies.

I pretty certain I can use js to generate a random number when the document opens and add it to the PDF, but could I extend that idea and add numbers sequentially to the number of copies being made?
