Digital BW, The Print

Roy, apropos of the exchange below, what DPI should we be using when
sending an image to QTR for printing on the Epson 2100?  720 or 360?

I'm using Qimage on a PC to send the image to QTR via QTRGui, although
this doesn't really matter.  UC inks and both matte and
pearl/semi-gloss papers.
