Font Squirrel is collecting free fonts which you can use in your business and for commercial print work.
On other free font sites you always have to read the font license agreements after downloading to make sure they are not just free for personal use, but also for business use, but not on this site.

This is what they have to say:

Free fonts have met their match. We know how hard it is to find quality freeware that is licensed for commercial work. We've done the hard work, hand-selecting these typefaces and presenting them in an easy-to-use format. Please help us by submitting your own free fonts or showing us where to find more. Thanks and enjoy!

So, head over there for your free fonts and help them find more.
