Question: will the interface between lpd and this program be an internal one, or a officially supported interface ? Will this be for instance where we will plug in ghostscript or a bidirectional communication postscript driver in the future ? I would be really neat if we simply changed it to have a generic queing frontend, to which you could submit files and processing directives, a queue manager which will take care of submitting one job at a time, in right priority/order and so on, and then configurable backends to do the job. That would allow the backend to du many other things than just printing. Can you say "job-queue" :-) -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
