I don't remember seeing this problem on the list.
KMail print on screen is clear and most letters are
separated. When I print out a mail, some letters,
particularly the "t", the "si" and the "sk" combinations
are scrunched together with adjoining letters.
I am printing to an HP 2200D laserjet. The
typeface on screen (and on paper) is a
sans-serif font. Even on screen, it is slightly
scrunched in spots. "ri" and "ti" and "tt" and
too close together.
