Notes from an amateur. I'm a field technician but I also write some documentation for my fellow technicians. This is nothing fancy, done in ten point font size, printed on the printer beside a desk at 600 dpi (sometimes 300), and then sometimes photocopied. I'm on a Windows operating system using various software. I want to acquire a few more serif text fonts.
1. What fonts are good to use? Many fonts (early Garamond versions, for example) are not so readable at 10 points size. Here <http://www.creativepro.com/story/howto/24908.html> is a helpful article, but I'm trying to get a little more.
2. Alternately, what fonts are not good?
3. Why is this area of font use seldom mentioned in font reviews or discussions or books? There are lots (and lots!) of people who could benefit. I would think anyone covering any body-text font should work this into the review.
4. Are there methods (research paths, whatever) I should be using to identify and acquire good robust fonts? How do I separate the fonts that are good for my purposes from the fonts that look great at 14 points, 1200 dpi on glossy paper?
