QTR-Quadtone RIP

Dave,

One thing that wasn't clear before is that your image seems to be in landscape
orientation i.e. 18in wide is really 18in length as printed.  So the whole image
must be rotated before printing.  I'm not sure whether Qimage tries to take
care of this but if not both the QTRgui front end and the QTR print code have
to do this rotation.   Although its not obvious the front end and print code are
completely separate and an error message from QTRgui really doesn't tell
whether the backend will work (this is why Stephen suggested to print even if
you can't see the preview). Anyway you might try rotating the image in Photoshop
before sending to Qimage.  This would at least see if that is part of the problem.
