I, and you, probably, are not dealing with printing confidential
documents. Those entities which are should be more concerned.

Remember, good though the research might be, there is as yet no
published POC and the ideas behind it do not appear particulary
easy to implement. I'm not expecting anyone with the necessary
equipment to be sitting in a car outside my house any time soon.
If I got concerned (and HP did nothing about it) I wonder whether
running arp would do anything to discover what is essentially a
MitM situation?

A timely fix arrives in Debian. Users who update are once again safe.
What more could you ask for? What can you say apart from "thanks"?
