     Got this in the mail today, regarding the need for PrGeneral in
printer drivers...

     I don't have Canvas 2.0, but HyperCard 1.2.1 works fine with my
DMP-110 printer driver, and this driver has no PrGeneral.  In fact, it
has only PDEF 4 and PDEF 0.  It may be that the printer driver Ian
tried with HyperCard needs something else, or that HyperCard wants a
PrGeneral under some combination of circumstances unknown to me.

     From looking at the TechNote in question (128), I don't think it
would be too difficult to write one, if it became obvious that
PrGeneral were a necessary part of the printer resource file.  Since
there has been no official word on this as yet, I assume for now that
it is not necessary, however.
