The Xerox high-speed printers are indeed write-white printers, while
the LaserWriters, LaserJets and others based on Canon engines are write-black.
We have found that some Computer Modern fonts work better with some
modedefs, while other CM fonts look better with other settings.
We have also found differences between the write-white modedefs for
the Xerox printers and those devised for Ricoh-engine based printers.
In fact, the Metafont settings for a given font often vary among Xerox
high-speed printers, or the little Xerox 4045 Model 160 PostScript printer,
which is also a write-white printer.

I will be sending Michel a private message with the modedefs we have
for our high-speed Xerox printers. I am interested in modedefs for
the 10ppm Xerox 4045 Model 160 where we print TeX via PostScript.

Also, in my humble opinion, I think the best way of printing TeX on
the Xerox high-speed printers is via the TeXrox driver, available at
no charge from Thomas J. Reid from Texas A&M University (email addr:
x066tr@tamvm1.bitnet). TeXrox runs on Unix, VAX/VMS, AOS/VS, VM/CMS
and MVS. It is an excellent DVI driver.
