Rough fonts

Pretty sure there is a setting somewhere cuz, all my fonts are very pixilated when I print out my invites.
Photos look good, but even the simplest fonts are rough. What do I need to change?
Thanks

make sure next to your fonts there is a box with the pixel size, next to that on the right, is a box with text styles. i had this problem once and it was because i didnt use one of these. simply pick one of those and voila your text should be smooth (h)
