QTR-Quadtone RIP

I've been helping friends print out the ink pattern page through QTRgui. I'm a mac user and have been using QTR for several years to make digital negatives. When we print the pattern page through QTR gui, each bar prints out in magenta, with a bluish background. Essentially, it prints out how the original file appears when you first open it. When I print through PS on mac, it prints out as it should, with all the colours represented. Anybody know what could be going on here? They are set up on a PC, Windows 8, PS6. They have the lastest version of QTR. Thank you.
