QTR-Quadtone RIP

I normally use ColorburstRIP. I downloaded QTR today to try out.

I have issues printing on 16inch roll paper with an Epson 7900 Printer.
Roll Paper length of 25.5 cm the print comes out the correct width and placement, but...
1 - with a black line printing down the  RH edge of the print. 
      (Side away from print head park position)
2 - the bottom 5mm of the image missing

At a Roll paper length of 15 cm things go very strange. I get a black line printing down the middle of the paper followed by the left hand half the image being printed.

OS is 10.6.8, CS5.5

Peter Miles
