These lines define what resolution settings QTR supports for the

you noted in step 1.

I had the exact same problem with my 9600 causing banding with 
bidirectional printing.  I tried this edit in the print-9600.bat 
file in QTR and it completely solved my banding problem.
Original line "set RES=1440x720fourp"
New line "set RES=1440x720fourpuni"

Thanks for the info.
