In Excel The Problem sometimes is, that you have a perfect looking page. Table high font size and so on, but then you try to Print it and you ge that your page is way to smal or too big to fill tha paper perfectly.
At moment, you have to manually ajust a zoom value but miss a live Preview.
(In most cases my tables are too small, and I have to Print them above 120% zoom.)
I propose to have an editable Live Preview where I could see how it would be printed, but I could ajust inside.
