Are you are aware of the 'download code' option that outputs a nice, printer friendly version of any code that is within a node?
Just look for the d/l code link at the bottom of your node, or just append a &displaytype=displaycode to the end of the URL.
This works great for grabbing clean copies of code, but of course, this doesn't capture any normal text.
Update: Yeah, I did have this feeling that you would know that that one :-). I'll leave my suggestion here though, for others who might not be aware of it.
I don't personally see a need for a printer-friendly version, as the current layout prints neat on my printer. But it's a valid suggestion, and ++ for providing code, which I'm about to d/l using &displaytype=displaycode and test :-)
Update 2: should this be posted in the snippets section?
