print from K-Mail run together

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 "th" are too close together. Suggestions? TNX--doug
