How to change print size in Yahoo

[Beth]

I spent hours trying to fix this. Suddenly, all of the e-mails in Yahoo that I wanted to print were so tiny that I couldn't read them. None of the help online does a thing. I finally paid $5 for help from Yahoo and after a lot of annoying answers from Yahoo that didn't fix a thing, the help person finally hit on a solution--change your browser from Mozilla to Chrome. It worked like a charm. She didn't understand why this worked, but I don't care. It works.
