Summary: Omnilaser uses a "write-white" engine

The Omnilasers use a Ricoh "write-write" engine while the
Laserwriter uses a Canon "write-black" engine.  You will
need fonts that are optimized for the Ricoh engine.  I think
they exist, but can't remember who has them.  If you can
get a copy of the latest TUG (TeX Users Group) Newsletter,
there's an article that talks about fonts and laser printers.
There's also a table that shows who has done fonts for the
various laser printer engines.  TI is not the the only vendor
using the Ricoh engine.  I believe QMS and Talaris are using
it also.

I have been told that "write-black" engines create slightly
oversized pixels whereas "write-white" engines create slightly
undersized pixels.  I've noticed that half-tone patterns with
few pixels look "OK" on the Laserwriter, but are very washed-out
or even invisible on the Omnilaser.
