Well I stopped avahi-daemon on the CentOS machine.  The CentOS machine is 
itself running BIND (it is the local DNS server) and does not use apt.  I 
stopped avahi-daemon on the CentOS machine.  The Ubuntu server is no longer 
reporting the HP printer in lpinfo.  Hopefully the workstations will stop 
reporting it too.  I don't run apt on the workstations -- they get updated 
when the Ubuntu server gets updated (their root and /usr file systems are 
shared off the Ubuntu server).

We really don't want i-device users sending lots of random stuff to the color
printer.
