Don't use PSP for the printing. It's limited in that respect.
Use IV. But I think it would be better if you can cut up
the quadrants. With the original open in PSP, measure
out 4 equal quadrants, copy those, then Edit - Paste
as new image. You should end up with 4 images about
600x900 each. Save each one separately:

TL.bmp TR.bmp BL.bmp BR.bmp

Then open each in IV and print it, selecting a
size of 6"x9". The result will be 4 pieces that
can be taped together. no overlap.

so much effort for such a simple task.
