QTR-Quadtone RIP

John,
I print routinely from Photoshop without saving the files. This is on a Mac running Leopard.
The Photoshop dialog box offers me the QTR printer as an option. Even if I forget to select it 
there, it is still available as an option when I go to the Leopard print dialog box.

It may be that in the windows environment, using QTR as a stand along printing application 
it needs TIFF files.
