I've read the official reply, but it's got me thinking.  Are these 
network connected? they sound like it, being an 'N' product.

It might be possible to create a totally separate duplex queue, pointing 
separately  to the duplex machine, and print to that?  It would 
certainly work with jetadmin on Solaris, I've done that sort of thing - 
an A4 queue and an A5 queue onto the same machine.

Never tried it with CUPS - my system was quite straightforward, two 
printers each with a unique queue, 'cos they were not physically close.
