I am the only Mac user in an office of Windows users. We use a ImagePrograf TM-305. When I print from PDF to Arch-D, 36" wide x 24" high, no matter whether I print in Portrait or Landscape, it prints 36" x 36". The image prints in portrait with the wasted 12" on the left side of the print. Obviously, this is a waste of paper but also make the prints awkward and I either have to go to the trouble of cutting off the excess manually, or folding, etc. I have downloaded all the latest drivers.

Any suggestions how to resolve? Thanks.
