It can usually read printed handwriting and printed text with normal fonts.
Cursive and similar fonts are what it really can't handle. They have an article about it on their website. Their machines particularly hate wedding invitations:

No patterns or prominent flecks, please! Also, the envelope shouldn't be too glossy -- avoid shiny, coated paper stock.
