... and I've found what produces it, thought it's still a bug.  For
some reason the presence of the printer on the LAN is what creates
these 'phantom' printers.  If I power the printer down both the
OKI-MC342-AE529C in Firefox and the 'print' in AbiWord disappear.

So their print option seems to somehow 'see' the network printer and
thinks it can be used.  As I said early on LibreOffice does things
right and doesn't see this phantom printer.
