I think that this is the kind of effect that you get when you turn on
"fractional fonts". The idea is to get the contents of the line on the screen
to match what it should be based on the fonts themselves. Since the pixel
placement sizing on the screen is fairly coarse relative to the definitions in
the fonts, the fractional font size capability mucks around with the screen
placement to get everything on a line that needs to be there, even at the cost
of cramming and spacing unnaturally.

The bottom line is fractional fonts on - lousy screen placement good
laserwriter plcement -- fractional fonts off - even screen placement good
imagewriter placement and spacey lines on a laserwriter.

Anyway this is just my guess from what I have observed :-)
