I'm not sure this is even possible.   Tray select, duplex, etc... are
often encoded in either the PCL preamble of a print job or in a PJL
envelope [common for Postscript].  They really are attributes of the
*job*.

I'd guess that Gtk/GNOME would have to 'emulate' this behavior by
splitting the ob silently into multiple jobs.  That could get wierd.
