The problem of write-white fonts has already been answered in part in
the Laser-Lovers list, but here are two more details.  My paper in
the Protext III Proceedings (Boole Press, P.O. Box 5, 51 Sandycove Road,
Dun Laoghaire, Co. Dublin. Ireland) discusses precisely that problem, 
and illustrates it quite effectively.  We are about to release the first
version of a font editing program which allows you to see the effect on
the screen, and further studies are in the mill.  The problem is
extreme in printers, and somewhat less so on black-character white-background
screens.  The Protext III paper (I am told that the proceedings are
through the press and about to be mailed) includes the listing of some
lines of code which will correct the effect somewhat in cmbase.mf if
you are using METAFONT.
