Just for those who may need, your way worked smoothly in my Fedora Core 6 box.
Cups doesn't support EPL-6200L, simply it doesn't work.
In my box it wasn't possible to rebuild the source rpm and I just used the .tgz file and
following the instructions at http://epsonepl.sourceforge.net/?page=howto
then i followed your procedure.
It works fine in my box.
