[Evolution] Printing in a very small size

[Gentoo_Newbie <gentoo_newbie netcabo pt>]

Hello.

I'm using Evolution 2.0.3 on Gentoo (mail-client/evolution-2.0.3-r2).
All works fine except when printing emails. Despite having a font size
of 12, the emails are print with very small chars, completly unreadable.
They appear like dots. If I look in Print Preview, the result is the
same. I can even zoom in several times, and really see that letters are
there and not trash.
To get an "acceptable" print output, I need to put the font size to it's
maximum, 72... and in paper (or Print Preview) it looks like I'm
printing in size 8.
This is not my printer's or system's fault, because I can print well in
other programs, such as Gedit and OpenOffice.
I also tried to print to PDF, and the result is the same. You can look
it here in :

Can anyone help?

Thanks
