[OS X Emacs] how to control colors when printing

[Pete Siemsen]

I tried various permutations of this in my startup file:

(require 'htmlize)
(setq htmlize-font-size-scaling-factor 0.02)

Nothing I tried affected the size of the font in the printed output.
Whether I setq the variable or not, or set its value to different numbers,
or did the require or not, the result was the same. 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.

I tried making the font smaller with Apple -, and that worked. To get a
good size for me, I had to do Apple - twice. That makes the displayed font
temporarily so small as to be unreadable (see attached screenshot).

I noticed that if I select text before doing Command-p, the text was
printed in black, which is what I want. With no text selected, the buffer
was printed with the colors that the text has in the buffer. I'm not sure
if that's useful, but it's nice that I can make it come out black.

So to print, I'll usually do:

Apple - (twice)
C-x h
Apple-p
Apple + (twice)

The problem will be if I forget to shrink what's on the screen before I
print.  When I do, not only will I waste the first printout, my vi-loving
colleagues who share the printer will certainly give me a hard time :-)
