Many responses in a short period of time, and most of them zeroed in on the
exact cause.
HP Jetadmin software caused a printer to use /dev/null as its device, which is
the cause.
Solution is to run latest release of Jetadmin software.
The command lpstat -s will show any such printer.
Thanks to the many who responded...
