Digital BW, The Print

The problem with QTR, at least in its Windows incarnation and the 
smaller printers, is that it is much less tolerant of blocked and 
misfiring nozzles than the Epson driver is, and that is possibly the 
cause of the banding. If you watch the print being laid down on the 
paper on for example the R2400 you'll see the ink is being laid down in 
a much narrower band as the paper passes through using QTR than it is 
with the Epson driver. (The lid is locked down on the 3880 while 
printing so I can't see how it works there, but suspect the same)
