I never got around to writing a print stylesheet for posts when I redesigned this site the last time, so I went ahead and did so tonight. It’s very minimalist and uses a serif font for printed readability (Georgia to be exact).
I’ve tested the output in Safari and Firefox on some of my more complicated posts with success. You can see the results by printing (duh) or just appending ?printonly=1 onto the end of any post URL on this site. Like so. Enjoy.
Obligatory screen shot.
