I shall resist the temptation to prove to all of you that I am a better
character asassin than Les Earnest. What I'd like to do instead is
remind you that this is a forum for the discussion of laser printers,
not restaurants, wine, or amateur comedy.

Further, I'd like to remind you that the way that we got onto this
tangent was that Les, more or less spontaneously, posted to this group
the statement "the character spacing on the Apple LaserWriter is
wrong". Since I know that this statement cannot possibly be true, given
that the LaserWriter can produce any character spacing that you like, I
tried simultaneously to assert the truth while exploring the motives of
someone who would make such an inflammatory statement. Les has
succeeded in throwing up a pretty good smoke screen to obscure and
distract from this spacing issue.

This is the end of the academic year at Stanford, and I do have other
things to do with my time than flame on Laser-lovers. When I get the
time, perhaps in the next few weeks, I will put together an explanation
of what the quantitative issues are in laser printer spacing, and why
statements like "the spacing on printer X is wrong" are often vacuous,
and why "blind tastings" have got to be done with a great deal of care.
A week ago I believed that Les was just being hostile about this issue;
I attributed his hostility to the fact that he is a major stockholder
in a company that perhaps stands to lose business if it ends up that I
am right and he is wrong. I now realize that Les really doesn't
understand the character spacing issues, and that he is just saying
what he thinks is right (as, of course, am I). Any system that offers a
lot of flexibility has got to have "options", or means of controlling
what it does. Any system that has "options" must have "default
options". If one has never used a system that offers any flexibility in
these matters, I can see how it could impair his ability to think in
terms of the big picture. 

I was hoping to find time to write the "tour de force" software, namely
a conversion program that would take an ImPress file and convert it
into a PostScript file that will print with exactly the same appearance
as the original Impress file did. This program is possible, though I'm
sure that until I actually produce it and show it around, nobody will
believe me (since I have given several times the explanation for why it
is possible, and nobody has paid any attention). I challenge Les, or
anyone else who believes that the Imagen graphics model is superior to
the PostScript graphics model, to write the inverse program, namely one
that takes a PostScript file and converts it into an ImPress file that
will print (on an Imagen printer) the same image that the PostScript
file did on a PostScript printer.
