QTR-Quadtone RIP

I'm printing just fine to QTR from Lightroom.  I'm using a Mac and an R1800 with NK7 inks.  
The R1800 is set up for the NK7 profiles and shows up as just a regular printer to Lightroom, 
and all i do is select it, adjust the settings in the print dialog, and it prints.

I haven't printed from Windows in a long time, but I'm guessing you just need to export as a 
TIFF and print through the QTR GUI.
