Hold Ctrl and scroll up with the mouse wheel. Edited to clarify, go to the home screen and select a file at random, do not open it.  look at your keyboard and find the Ctrl button on the bottom left.  HOLD IT, grab your mouse and look for a little wheel that scrolls.  Scroll it up to enlarge, down to shrink text size.

I also need to know. The print is way too small and not sure why it has to be this way. 

still....Hold Ctrl and scroll up with the mouse wheel.

Yeah, Everyone understands what a mouse wheel does but that doesn't work when using a laptop with no mouse. I just enlarged the overall text size on my laptop. You can enlarge forms inside returns if you go to view and scroll down to whatever size you want.
