Normal on the things I've seen, (not Wintel), this is done by enabling banner page printing on the print queue which then prints this sort of information.
Still unsure how this is done mate.
Banner pages are what they are called in Novell Netware. I dont think he was refering to a Microsoft network method.
added: take a peek at the following page, it should give you a bit of an insight into MS seperator pages:
