Pretty much any distro will get a web browser up and running. However, the problem is going to be all the plugins and codecs that allow for a rich browsing experience (Youtube videos, java apps, other multimedia). No linux distro (of which I’m aware) has all that stuff configured “out of the box” due to legal/licensing concerns. (there may be some I just don’t know of any). So there is a one time cost involved with getting all that stuff going. Printers the same way.
Least painless way to get that going is probably to pay or barter with a known expert to get over that one time hump. After that it should be smooth sailing for an install that just has to do basic browsing.
From a net cost perspective you’d still be way ahead particularly if you can work something out via barter.
