Netware 6.5, sp2
iPrint client 3.0.9

We have set up the drivers in the Broker, set up several iPrint
printers, created a couple of printer driver profiles, most of which are
to include duplexing and an extra 500-sheet tray. I modified the
printers and their drivers to select the appropriate profile.

I go to the iprint.<domain>.com page and install one of the printers. I
check the details, and none of them have the duplex selected and no
extra trays.
