Well, page counting in lpd is normally done via the accounting filter (if in printcap), but that's if you want to *log* the page count. It's expected to finish in a timely manner, so having it wait for a human user may screw things up. If you want the user who *submitted* the job to ok it being printed, you should just put a wrapper around the lp/lpr commands. If you want another human being to approve the job being printed, the input filter might be just the ticket. Or maybe you want to use the output filter (of) instead. Final note: counting pages can be *hard*. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
