[OS X Emacs] how to control colors when printing

[David Reitter]

You know that you can just do C-x C-e with the cursor behind an s-expression (like the seta-expression) and try out its effects?  Faster than starting up Aquamacs.

I tried it now, and it doesn’t work for me, either.  I’ll look into it.

I've attached a sample that I scanned. As you wrote, it allows about 60 characters across the page. I think the font is a bit too large. I'm likely to print some source code, which wall rarely fit at that size.
