It could have a filter added to send a file through a2ps on its way to the physical printer. You could wrap a one or two line shell script around lpr to do the same thing. a2ps generates postscript for the text input It adds a flag to print duplex in that postscript. The printer interprets that and does what you asked. You can send a postscript command string to set the printer into duplex mode and another to reset it. I don't remember it offhand. It's one or two lines to set a value into devicedict or systemdict. If you look at the a2ps sources it's in there. Geoff Steckel
