Ross,
Thanks for your response. All the printers are networked and none are
connected to the server's usb ports. In fact there is nothing
connected to this server's usb ports.
In looking at the cups error logs I am getting abundant entries of :
(/usr/lib/cups/backend/ipp) crashed on signal 11!
I turned on cups debug, but did not learn anything else.
Thanks again for your help,
Greg
