Dear Friend I would like know how can tell how much space left on my Mathematica notebook in an A4 paper format. So I would have to use page breaker or pdf generator to address my presentations.
Thank you.
As far as I know, you can only do this in the vertical direction, though Mathematica does an OK job of the horizontal for you.
