TI Omnilasers use a write-white print engine.  The other printers you 
mentioned as having used previously use a write-black print engine.  This
causes differences in the effective pixel size (consider forming a character
by marking the background with round dots vs. marking the character itself
with round dots). 

You will need to make a new set of fonts for the Omnilaser.  If you don't
already have a recent version of Metafont, get it and look for the file
README.WRITE-WHITE.  You may also need to modify your spooling software
so that the correct fonts are used for each printer.
