I am running OES NW 6.5 SP5 with iPrint. I created the Printer and
associated the printer driver profile (with duplex option enabled). I can
install the printer and it should up as duplex enable and everything looks

However, when I access URL hostname/ipp and click INFORMATION icon that is
associated with the printer. It has the Duplex and it is said to "No".

I tried to edit the printer object but don't see the option to specify
duplex feature.

Hope someone can help.
