QTR-Quadtone RIP

I'm getting microbanding with the Epson 4800 when printig on film for digital negatives and 
and trying to determine if there are ways to adjust the settings to eliminate it.  I will try the 
various dithering patterns in QTR, but I have one additional thought...

Does QTR override the printer paper configuation settings?  I can set up a paper type in the 
printer that has a specific adjustment to reduce the advance rate.  That would eliminate the 
banding if the problem were through the Epson driver, and also if QTR uses the basic 
infrastructure to advance the paper that is part of the Epson command structure.

Roy, (or anyone) any thoughts on this?
