Yeah.  The only thing I can think of is that the JD port 9100, 
understands postscript, where as the ipp port does not, and you need 
to then rely upon the printer to handle duplexing the document (i.e., 
page layout, not just the page flipping).  I'm speculating that using 
the JD port allows you to send the raw postscript to that port 
pre-formatted for duplex printing, and then the printer interprets 
that in order to be told which way to flip; long or short edge.

Of course, this all speculation, all I know is that I just printed a 
250 page doc 4-up/duplex through cups and it worked fine.  I'm happy
(well, not really, but it's working better than the old method of 
converting pdf->ps->a2ps for 4-up/duplex->smbprint :)

	It may look like I'm just sitting here doing nothing,
   but I'm really actively waiting for all my problems to go away.
