Digital BW, The Print

I am looking for a printer to do B/W printing. I need the best of the 
best as far as quality is concerned and need to make prints at least 
16x20 in size.

Fortunatley, I have a large job and money is not an issue.

Based upon today's state of the art what would be the best combination 
of machine/ink/quality/rip etc. available.

Thanks
