Thanks for looking into this. I would be happy to test this. I'll
get back to you at some point.

I don't think this is right. If I have configured my printer to do
duplex, this would force it to simplex for this document.
The correct behaviour is simply not to mess with this at all. I can
see no reason for anything generating PS output to do so, and frankly
I think it's mind-boggling that this code is in Poppler at all.
The right patch is probably this:
" /PageSize exch def",
" /ImagingBBox null def",
" /Policies 1 dict dup begin /PageSize 3 def end def",
- " { /Duplex true def } if",
" currentdict end setpagedevice",
" } {",
And that is what I plan to test.
Ian.
