Hi.

Most emacs users that I have talked about this problem aggree that hitting
accidentally the print screen buttom prints the buffer WITHOUT prompting
is really annoying. I have lost a lot of paper and pacience in this way,
and so a lot of people for sure. If developers don't want just unbind the
print buttom (the best solution), a simple yes-no confirmation would not
harm a printing friendly user. Just a y-n confirmation is not enough,
because printing is always expensive. There is the "Print Buffer" menu
item for that.

I have solved globally binding [print] to some message in my .emacs.

Amazing how this unfortunate "feature" resisted so long...

Thanks.

Miguel.

If I start emacs-21.3 with the -q and --no-site-file command line options,
`C-h k` tells me <print> is undefined.  Perhaps you or Redhat have bound it
in site-start.el, default.el, or ~/.emacs.

I recommend using advice for this:

(defadvice print-buffer (around confirm activate)
   "Request confirmation when called interactively."
   (if (or (not (interactive-p))
	  (yes-or-no-p (format "Print %s buffer? " (current-buffer))))
       ad-do-it))

The Emacs maintainers might consider adding a confirm-print option.
