Digital BW, The Print

I understand that the Epson 2400 driver doesn't do Black Only printing. 
What about using QTR for this?

My two 1160s are overdue for retirement, and I'm considering replacement 
options. The 2400 looks like a good do-it-all A3 size printer that can 
do both colour and B&W. But I'm interested in ways to keep ink costs 
down, and in the aesthetic attractions of BO printing.
