QTR-Quadtone RIP

Hi,
I am a registered user. I hope it is ok to discuss this issue here.

I have a TIF file (kind of large).

That I printed with QTR by opening the file.
	Windows Vista x64
	Epson Stylus photo 1400

When I print it on either 11 x 17 or letter size, There are bands
on either side as exhibited in this scan of the 8.5 x 11 print.
