Enabling LPD backend

["Jesse B. Crawford" <jeanluc nmt edu>]

Hello,
We (unfortunately) still use lprng for printing. In
/usr/lib64/gtk-3.0/3.0.0/printbackends we have libprintbackend-lpr.so.
In applications using gtk2.0 (e.g. Firefox) the Print menu has an "LPR"
option that allows the user to enter options to the lpr command in to a
text box below the list. In gtk3.0 applications this option is missing.
I have tried changing settings.ini to include gtk-print-backends =
"lpr,file,cups", but this doesn't seem to have done it. gedit, for
example, still does not have the lpr option. I suspect maybe this
setting should go in gconf now, but I can't see where.

How can I properly enable the lpr print backend for gtk 3.0?
