This means a couple things. First, your zone is configured to allow
dynamic DNS updates, which can be okay, but usually you don't want
this for a zone containing fixed records.
Second, it means that client updates is allowed. This can be bad, and
generally when I set up dynamic DNS zones, I only allow updates from
the dhcp server (usually the same box, so it's restricted to localhost
doing the updating).
Essentially your printer is trying to update its record and removing
the old one, but not publishing the right one, either through
permissions or some other reason.

How do you have your zones and/or dhcp server configured? Can you
sanitize them enough to post them?
