Digital BW, The Print

I would like to print B&W photos using the Epson driver and ABW
with an R2400 and/or a Pro4800.
However, I would like to force the driver to use only the three 
black inks of the K3 inkset, with no intervention of the colored
inks. Which settings should  use in order to do that?

Cheers,
   Daniela
