Thanks for taking the time to do this.

The reporting of rdar://problem/15008524 might have been occasioned by
the discussion at

  https://discussions.apple.com/thread/5505965?tstart=0

and there seems to be some relevance to the problem here:

The raw queue test can printed to with

  lpadmin -p rawq -v ipp://127.0.0.1/printers/test -E

and

  lp -d rawq /etc/services

If test is shared it can process a job sent from a remote machine.

Regards,

Brian.
