QTR-Quadtone RIP

All,

I am new to this group and just started to use QuadtoneRIP. So far, I 
am quite impressed my the neutral prints from my Epson Pro 7600 using 
QuadtoneRIP.
However, I am wondering if there is a way that I can print A2 format 
from 24'' roll feeder horizontally? I know that you can select portrait 
or landscape, but at the end Quadtone always print the picture 
vertically from roll, no matter whether you set the image in landscape 
or portrait.
When I print out from CS2 with the Epson driver in roll feeder mode, I 
have the function of auto rotating. What this means is, if I have a 
roll of 24'' and print in A2 the auto rotate will flip the A2 image 
horizontally so that no paper is wasted and less cutting is required.

Any hints or advices are welcome.

Thanks,
Thai
