Why don't my printed wiki entries look like they do online?

I don't want to have extra spaces between lines when I print out pages -- or more precisely, I want the wiki entries I print to look how they do in the web browser. ... Even when I do the "print version" button, additional spaces magically appear, especially around bullets...

Finally, I would like to be able to save wiki entries as Word docs or PDFs, if possible, and I would like to be able to copy and paste a word document into a wiki entry without losing the formatting.

I am trying to get a business on board to use the wiki, but these are some of the issues that bring about a lot of resistance.
