I have a presentation with several images and a dark background. So it should be very expensive printing it.
Is there a way to printing in a "toner saving mode", ie, just black/gray color font over white background.
Mostly I ask for a software configuration way. But hardware solution is welcome too.
I am using "libreoffice" in linux and my printer is a Samsung ML-3471ND (laser B/W).
EDIT: Something like
Edit->[print in a very economic mode] or
Format->[automatically turn background to white and foreground to gray scale] etc... or maybe some printer setting.
EDIT 2: @diogo-rocha Why deleted your answer and my (an another user's) related comments? What is the constructive idea behind that behavior? Please think first in the community convenience.
