Hmmm.  And how does this differ from what happens in Cygwin when GV
sends PDF to a printer via LPR?

Hmmm.  Still something I am not getting:

1. GV under Cygwin can display the PDF fine.  That's what GV is meant to
do -- be a viewer for PDF/PS.
2. GV has a print capability.  By default, it (seems to) uses LPR for
the printout mechanism.

Therefore, if #2 ever works, then there must be an assumption about how
it works that works for most (all?) printers.  What is that assumption?

Undoubtedly.  Under Adobe, the print capability works whereas, under GV,
it doesn't seem to work.  I still do not have a means of determining
why.
