Well, not entirely -- the Updating your software, OS X & printer driver
certainly pertains. Those are always foremost considerations. However,
problem as you describe it now is a little different than what I understood
from the "prints up" expression in your first message.
It sounds like what you're saying now is that increasing the font size
causes the row height to change but -- on screen -- the size of the
characters doesn't appear to increase. Apparently it has nothing to do with
printing at all... Is that correct?
If so, the first thing I'd suspect is that the formatting of the cell is set
to include the Shrink to Fit attribute. Select the cell then go to Format>
Cells - Alignment. Clear the Shrink to Fit checkbox & see if that fixes it.
