After a lot of investigation and conversation with IBM folks, we concluded
that the -C support was omitted from the AIX 3.1 line printer code.  There
is some evidence that the generalized queuing mechanism of AIX, which is
layered above line printer support, is to blame.

Our reluctant choice to recover -C support has been to abandon the AIX
printer system and install our own local package.  That's not an attractive
answer, but if your need to pass printer-specific information matches ours,
I think it's the only choice right now.  (At least it wasn't too hard to
port our local line printer system.)
