WEBSITES SHOULD BE PRINTABLE

Summary from the TLDR Design newsletter

Websites containing substantial text can provide a much better printed experience with a relatively small set of dedicated CSS rules. Print styles can remove navigation, introduce print-only information, resize typography, adapt code blocks, and turn colored links black so pages work better on paper. Supporting printing may be a niche requirement, but it reflects a broader approach to good software in which small, thoughtful accommodations give users more ways to experience content.
