Okay... I can ping the printer via it's ip address. I cannot ping by
name and, I am not running bind nor is dnssec-conf installed. This
problem is also network wide because none of my machines can print
anything anymore.  I still get the message 

"paused /usr/lib/cups/filter/hpcups failed"

And CUPS administration won't let me unpause the printer nor carry out
any administrative function.
