printout quality: how to get rid of pixelated fonts

[urlwolf]

I have sent a few email reports on this, but just in case.

I have printout quality problems (paper only - on screen it looks beautiful) that force me to use acrobat to print. When using Xchange, I get pixelated fonts. even if the settings are 'always' use curves. Why is that? acrobat does it ok.
Is there any way to get rid of the pixelated fonts? Why I mean is that you can see grey dots in the fonts if you look closely, whereas it's solid black when using acrobat.

I sent examples over email.

Thanks

I am using xchange viewer 2.5. I have the same problem. But why no one reply it. The same pdf document printed by acrobat reader is very clear, but with xchange its fonts are with little dots.
