[pdftex] Duplex printing?

[Geoff Russell]

Hi,

I have just got a duplex printer (Kyocera). From openoffice I set the
duplex box and it works.
I can set the printer to duplex with kyocera magic codes and send it
some handwritten
postscript and it works.

But when I send it a pdftex'd file, it prints simplex every time. I can't find
anything in the pdftex manual. Is there a way to get duplex?


Cheers,
