printing an article in black and white

[Allan Gottlieb]

My fast printer is a black and white laser printer (HP P2055dn).

>From the summary buffer, gnus-summary-print-article prints the article
with light colors printed in lighter grey.  This causes some to be
nearly unreadable.

Can I arrange for gnus to print all the characters in black (or at least
no lighter than a fairly dark gray)?

I would then invoke this revised function when printing to the fast B&W
and the normal gnus-summary-print-article when printing to the slower
color all-in-one.

thanks,
allan
