Cannot print from mate desktop

[James B. Byrne]

FreeBSD-11.2p8

Following a massive pkg update this morning, followed by a
freebsd-update install and restart, I now discover that I cannot print
from the mate desktop.  When I print from any application on the
desktop, libreoffice, pluma, firefox, the printer dialogue shows up,
the print job is generated, but nothing prints on the printer.  Nor
can I find any printer management applet in the toolbar.

I can print test pages from cups web admin. At least that is what the
software claims.  But they do not appear on the printer either.  Nor
are they reported in the lpr queue or on the CUPS web admin page.  The
printer self test page can be generated from CUPS.

The spooler appears to be working.

But CUPs reports two jobs as stopped and restarting them does not get
to print. Instead they show up in the completed job list as aborted.

cat /var/spool/lpd/np4172/status
sending to np4172

Enscript from the command line prints, but the duplex option selected
did not have any effect.  I reused an earlier command which had
previously printed as duplex.

Is there a package required for mate to have printing capabilities? If
what is its name?
