Digital BW, The Print

Hi everyone, this is my first post but already this group has helped
me a good deal in getting started with digital B&W printing.  Now I'm
trying to find out if anyone has found a BO solution for the 2400, but
there doesn't seem to be much information about this anywhere.  I
suppose most people aren't interested in the 2400 for BO printing, as
it is an advancement upon its predecessors primarily for its
continuous-tone B&W, but I was hoping to be able to do color,
continuous-tone B&W, and BO all on the same printer, as I'm moving
abroad and need to take a minimum of equipment.  I thought the Epson
2400 was the machine for this and bought one last week, rather taking
it for granted that I could do BO on it.  Now I'm reading that the
Black mode uses color inks, which is frustrating to say the least. 
Why is such an expensive and sophisticated printer incapable of one of
the simplest and oldest B&W printing approaches out there?

Naturally there's no point in such questions.  What I'd really like to
know is if anyone has had luck in finding a workaround.  Perhaps
printing from a RIP like QTR would do the trick, as I understand that
this bypasses the Epson driver?  Has anyone experimented with this?

Thanks in advance for any help.
