问题 I really like how http://www.honorshaven.com/ looks printed (to pdf). I've looked through the source to try to figure out how they did it (my navigation always turns into ugly bullet lists on print...) -- and I'm at a loss. Anyone know? Any help would be awesome!

问题 Ok, so I'm trying to print from a webpage (the typical "print" button, but I don't want the print dialog to appear) so I decided to use my already existing node.js backend to do the task (mainly because printing from browser is nearly impossible without the printing dialog).
