Live editor - How to change the font size of the printout? And no output except plots

Hello I am running 2017a on a mac. My first problem is with the font size of the printout. It is rather small and I wonder if I can change it. I had a look at Preferences but didn't find anything that helps me with that.

My second problem is that I can not see the values of a variable on the right panel or even inline. What I did was to remove ";" as I normally on the matlab prompt. disp(variable) didn't work either. What am I doing wrong?

Many thanks

Ed
