My Windows 7 computer has now become inconsistent in the specific failure.
This morning I tried the check printing module again and printing a report
and somewhere in the sequence I got a "not enough memory" error and GnuCash
crashed.  This machine has 24 Gig of RAM and 296 Gig free on the C drive.
Skip the next paragraph to read my conclusions.

After restarting GnuCash 2.6.18 working on a file on my local C drive when
I try printing I get the dialog to select a printer, I notice that it is
pointing to my favorite LAN printer, press print and the dialog box
disappears, but nothing goes to the printer.    Looking at the printer
queue I now see four 15 meg 2 page documents from Gnucash sitting there
growing grass or whatever documents do when they do not come out to the
print tray.  I discover that the paper tray is empty.  Oops!  I pause the
documents in the Queue and reload the paper tray.  Page 1 of 6 of a 2 day
old document comes out.  The rest of that document seems to have gone to
the bit bucket in the sky.  Now I try resuming one of the reports from
GnuCash and it appears in the printer output tray.  Similarly, a 1 page
test document from Libre Calc comes out and it is identical to the one that
was stuck in the printer memory from yesterday.

I see that GnuCash does have a different interface to the system printers
than most other programs.  My current hypothesis is that interface somehow
choked when the printer 'went offline' because it was out of paper and when
it crashed it took GnuCash with it.  After restarting GnuCash the printing
interface was able to route jobs correctly to the system queue for the
selected printer.  Since I am currently unable to reproduce the out of
memory error or program crash so far, that is just a hypothesis, but the
developers may be able to suggest a better test.  This could still be
related to recent Windows updates because some recent hardening seems to be
fiddling with permissions to work with printers.

I have had a different computer with Ubuntu 16.04 suddenly become unable to
print due to an obscure permissions issue to that same LAN printer after an
update, and I still have not been able to fix it.
