Small laser printer for Ubuntu - recommendations?

[Chris Green]

I'm after a small, i.e. reasonably transportable, laser printer that
works well with Ubuntu (actually xubuntu but that makes no odds).
Mono is fine, a scan facility would be really nice.

I don't want to spend a lot, price of consumables isn't all *that*
important though as I have a big laser printer at home which does all
the bulk printing.
