I have an aluminum iMac running leopard. Recently, I tried to modify the font size in Safari to make it easier to read web pages, and created some issues for myself - I increased the default font size. But then I found that if I printed something on the computer, it came out too large. So I starting fooling around with the font settings and zoom. Ultimately, I decided to go back to a larger font, 18 - but when I did that, it now looks tiny on the screen, maybe 10, and I have to zoom to enlarge it. What controls the default font? I think I would like to start from scratch but can't figure out how to go back. Thanks.
