why why why...

I have been reading about pixel fonts all morning and have studied them before this too.

The ONLY way I can get them to look decent is if I check "use device fonts"

BUT
if you check that, then others may not be able to view the fonts correctly right?

Well I am using them at the point size they specified, and have them on whole values etc.
Still fuzzy,

Please help. I have no clue.
