I don't print out much code. But when I would travel in the midst of developing some code I couldn't part with for a while, I have been known to use a2ps (anything to postscript). I'd have to review the man page again, but I would print out a module two columns to a page to good effect. It lost very little in translation and offered some suprisingly useful highlighting.

The other day I read something here about editors for working in perl and based on a recommendation in that thread, installed and tried out scite. It provides menu options for exporting to html, rtf, pdf, latex and xml. I'm curious to see the LaTeX. And I tried the pdf and it looks good. If I have X available and am not limited to cli tools, it has likely just become my preferred tool for this task.
