Description of problem:

Trying to figure out why I am getting an output scaled down by
a factor of 0.8 I removed the only configured printer and tried
to configure one from scratch.  Actually of a precisely the same
type and configuration as the one which was there previously.
'system-config-printer' decided to throw many errors while doing
that.  To wit:

After all that noise I got a configured printer back.  There is only
one on that system.
