"intelligent" load balancing or duplex detection

[Elvin Lee]

Hello everyone,

Many apologies if this has been addressed before in this newsgroup ... I 
tried to do searches for this subject, but I did not find anything 
appropriate.

I have two printers down here at the undergraduate labs -- an HP 
LaserJet 8100N and an HP LaserJet 8100DN. The latter supports duplexing, 
the former does not. Currently, the two printers are configured on a 
machine which functions as our print server. A class is also present, 
which contains both printers. Client computers print to the 
ipp://server/classes/balance class, so their jobs are sent to one of the 
two printers, as appropriate.

The problem, of course, is that only one of the printers support 
duplexing. Is there a way that I can configure cups on the server to 
automatically send duplex jobs to one of the printers in the class, 
rather than choosing between the two?

Any other elegant solutions are welcome as well...

Thanks in advance to any who can help. :)
