Typeface colours in postscript

Typeface colours in postscript

[Edward Lilley]

When I print messages from within Gnus (with A-P), the resulting
postscript file uses exactly the same colours as are used when messages
are displayed within Gnus.
However these colours are generally a bit too close to white to be
legible when printed on ordinary white paper -- is there an easy way to
quickly adjust all the colours in the Gnus face, or am I stuck with
telling M-x customise to never allow any colours in postscript files?

thanks,
Edward Lilley

I've had a peek at the article printing code, and it seems quite
suboptimal.  It redoes some of the highlighting, but not other bits, so
I've now rewritten it to print the article buffer as is instead of
semi-re-highlighting it.

Anyway, the problem seems to be a more general Emacs problem: If you
have an Emacs that you're running with a dark background, then the fonts
you're displaying are usually quite light.  Using
`ps-spool-buffer-with-faces' will then print stuff on white paper that's
totally illegible.

I don't really see any way to fix this is a general way -- what text
colour is too light to print, in general?  So I think if you use a dark
background, you really have to set `ps-print-color-p' to nil.
