Now here's an interesting datum:  I can print from the server's command
line using the lp command, but when I try to print a test page from
CUPS (2.4.2, if that helps) nothing prints.  The print job shows
"connecting to printer" then goes away, as though the printing had
finished.  I suspect this may be related to the reason I can't print
from my Ubuntu laptop.
