Lani,

The Imagewriter II, in Best mode, uses screen fonts which are twice the
displayed size, scaling them down.  In other words, normally, screen fonts
have a resolution of 72 dots per inch.  2X fonts, scaled down, have a printed
resolution of 144 dpi.

The Imagewriter LQ, in Best mode, uses 3X fonts and scales them down to a
third.

E.g., to Print 24-pt characters, you'd need a 72-pt size of the same font.
The printed image (LQ) will be 24-pt characters, but with a resolution of
216 dpi.  The Apple Laserwriters have a resolution of 300 dpi, so this may
give you some idea of the quality of the LQ. (about half-way between IW II
best mode and LaserWriter output).

As for speeds, I'm not really sure, but I think that in printer draft mode,
the IW II, is about 180 char per sec., and the LQ might be about 300 cps.

Hope this helps,

Jeff
