The bug report was already submitted, and it is classified as "high priority". The author wasn't complaining about the printer not working; he was complaining that the bug wasn't fixed (and that it shouldn't have been let to the system in the first place (the printer worked on previous version)).
I would assume that the printer was meant just as an example of the problem (which is that new releases may break things that used to work).
That said, I've been using Ubuntu as my main OS for about 2 years and I've never had any real problems (that I didn't cause myself...) with it, so I don't quite agree with the author.
