Write-white printers are, in general, a problem. They are, also, usually
quite fast and on occasion inexpensive. Many moons ago, it was suggested
in TUGboat that one make a mod to the macros of MF to prevent any line
from being less than two pixels wide. This, however, is not a very
robust solution (Levy's Greek fonts, for example, break under the 
pressure).

In experiments at Texas A&M University whose results were never
published, it was found that for optimum results, no fewer than
10(!) mode_def's were required to create fonts for their Xerox
high speed printers (9700s and 4050s). Because this work was 
never published, I doubt that similar mode_def "sets" exist for
other printers.
