I have a picture behind my text on the slide master. When I print, even if I
select "Black and White only," it still prints this graphic, using huge
amounts of toner and making the slides basically unreadable. In color,
they're readable, but again that uses huge amounts of toner or ink and not
everyone has a color printer.

Is there any way to define something like a print Master that lets me
specify to leave out the graphics behind the text for printing? Any other
options?

Thanks,
Colin
