I have 2, 8 port switches, a newer managed one here and an umanaged one 
in the garage.

One of the machines on the garage switch has all the profiles showing in 
its print requester, but logs no permissions in the error_log here when 
I try to print something.  Another machine plugged into an adjacent 
socket shows nothing but cups-pdf in that same menu. I could move cables 
to see if that has an effect, tomorrow maybe.
