Digital BW, The Print

I want to print an image on transparency film using my Epson 2400, but 
I only want printer output to be 720 DPI, which is fairly low 
resolution for this printer--but I still want a fairly good quality 
image with good blacks and no banding. 

Advanced BW mode only prints at much higher resolution. And I've tried 
selecting the "Fine" quality setting (which goes with the plain paper 
media and is supposed to be 720 DPI), but the print was poor quality, 
the BW was made up of colors which you could see, and the image had 
banding. 

I'm left with two other options I've though of: find the correct media 
to use "Image with Text" quality setting (or whatever its called, but 
that's close) which is also 720 DPI, or try using the Quadtone RIP, 
which allows me more choice in selecting output resolution. 

Any other suggestions or thoughs on these methods.

Best, David.
