QTR-Quadtone RIP

I am also having difficulty with centering!

I am using QTR 2.5 which I installed after uninstalling the prior 
version completely (and deleting the QuadtoneRIP directory).

I just upgraded to the R1800 from the R800 and am having a different 
experience printing from the R1800 rear manual feed (roll paper) 
slot.

I have a photo that is 6.67 by 10 inches (portrait orientation), 
which I am printing on letter sized paper in QTR. 

I've tried a number of ways to modify the file in Photoshop and 
print it in QTR using the manual roll (rear) input.

Printing at 100% in QTR - Perfectly centered.

Printing at 90% (to get 6x9 size) - Not centered. Prints off the top 
edge.

Resized to 6x9 in Photoshop, printed at 100% - Not centered. prints 
off top edge.

Resized to 6x9 in Photoshop, with white border added to make it 7x10 
inches, and printed at 100% - Not centered. prints off top edge.

Resized to 6x9 in Photoshop, with white border added to make it 7x10 
inches, and then a black 4-pixel frame around the edge of the 7x10 
image, all that printed at 100% - Perfectly centered.

I don't know if this is reapeatable - need to get some cheaper paper 
before I do any more experimenting! But thought I'd post in case 
this information sheds some light on the centering problem from the 
rear manual feed slot.

Roy, thanks for all your hard work on QTR - it produces amazing B+W 
prints!
