Why not just use good microfiche. Then it would be waterproof, as well as more compact than any dot printer could achieve.

  Good points, but I think it would be a lot easier to keep paper dry than microfiche cool; the former can be done passively, the latter requires active systems for most of the world.

    Just dig a big hole. Once you get into the earth a bit, the temperature is a constant coolness. Plus, an old mineshaft is a pretty good candidate for surviving some "end of the world" scenario.

      Yeah, but that cuts against the "people being able to find it again" problem.
