You can dispute it as much as you want but I am sitting in front of a
machine running ubuntu-10.04.4-desktop-i386 with a print queue set up
for an HL-3170CDW with Brother's packages. The GTK print dialogue shows
Two-sided printing as "Not available". Does your setup show something
different?

You didn't comment on this but I'll add that the greying-out is a
red herring (as is the invoking of poppler) as far as the cause of your
problem with duplex printing is concerned.
