|I am having trouble using the standard GF fonts with
|a TI omnilaser.  I have been told that the problem is
|that the fonts that are normally distributed are
|designed for an Apple Laserwriter, which smudges
|pixels considerably, and hence look bad on a 'cleaner'
|output device.  Can anyone confirm or deny this?
|Does anyone have a set of Computer Modern fonts
|(either gf or pxl), that look nice on the TI Omnilaser?

The correct explaination is that the Ommilaser has a Write-White engine
as compared to the LW, which has a Write-Black engine.  This means the
white areas "bleed" into the black of the "ink".  As a result,
characters look "skinnier".

You don't mention what system you run TeX on. One solution is to
generate a set of fonts tuned for the Ommilaser with METAFONT.  Another
(I've heard) is to get fonts from TI in ROM.

By the way, why are you using gf or pxl fonts? Pk is more compact than
either.
