I love reading printed books and blog posts. For those interested, a starting point for printable CSS is Gutenberg[1]. This has been my go-to for the print media in CSS. I believe I stopped looking for another one with my lack of deeper involvement in development of styles.

I'm also guilty of picking Baskerville as the default classic look to printable font-family and even had resorted to it for screen.

Besides the tools mentioned in the article (Vellum and Atticus), Ulysses also has a good option for print-ready output.
