That matches what I saw on Windows.

My guess is that the Epson driver uses every jet on each line of 
printing as it goes up the page, while the dither that QTR uses uses 
fewer jets (possibly only one or two) and so the impact of one misfiring 
is much greater. (With the Epson driver you can see the image gaining 
density as it moves past the print head if you lift the lid and hold in 
the front while printing)
