Sharing Printer Features


I have a Canon MP780 attached to my powermac. When I print from that machine, I can select automatic duplex printing and all is well.

I have it set up for printer sharing. However, from my powerbook, I don't have the same options when I print, and cannot print duplex. Any ideas on how I can get this to work? I even installed the printer driver junk that came with the printer, just to be on the safe side.
