PostScript fonts and the printers they run on are not cheap.  Downloadable
fonts usually cost more than $100 each and Adobe PostScript printers sell at
a premium of well over $1000 to non-PostScript printers that use identical
marking engines.  Having invested large sums of money in PostScript fonts
and printers, it seems reasonable that a customer can expect a font upgrade
option that is at least slightly cheaper than repurchasing the font *for each
printer*.  The vendors of popular software packages like WordPerfect, Lotus 123
and Adobe Illustrator-88 have such policies.  Is there such an upgrade policy
for Adobe fonts?

In a small configuration of a single computer and a single printer, this is
a straightforward task.  But in a large network of several printers and
computers this quickly becomes a big system management problem.  Do you have
any advice on how to deal with this problem other than to upgrade every
printer in lock step?
