Thats really interesting.

Most Professional Printers (as in a business not the things that print your documents out) for body text (paragraphs where font sizes are 12 point or less) tend to use Serif fonts because they help the eye to read each character more easily. Serifs for those who don't know are the little feet used at the ends of characters such as X.

However Verdana is a Sans Serif font (without feet at the end of the characters) which is used extensively for headings (larger font styles) in documents. Serif fonts do not lend themselves to large font styles 14 point or more.

Serif fonts are considered more readable for lengthy text printed in books, newspapers and magazines, whereas sans-serif fonts are considered more legible on computer screens. Most web pages employ sans-serif type for this reason.

I find long documents that use Sans Serif fonts for paragraphs difficult and tiring to read. I don't mean 1 or 2 paragraphs.
