QTR-Quadtone RIP

I think I found the problem in Adobe Forums:

"...yes, printing in OS X 10.5.8/10.6.2 and Photoshop CS4 with certain driver (notably the recent Epson drivers) is problematic. The reason is that Apple, in their infinite wisdom (NOT) has decided there is no such thing as an "intentionally untagged file". So, unless the print driver reports CORRECTLY under both the application _AND_ ColorSync what the correct ICC profile is, ColorSync will "helpfully" to a transform from untagged to "Generic RGB"...which in the case of printing intentionally untagged targets, will totally screw up up the process...
 
If you can, print out with an earlier version of Photoshop (before CS4) or, alternatively in CS4 take the target and actually "assign" and arbitrary color space profile such as Adobe RGB. Then in the CS4 Photoshop Print dlog, be sure to select the ICC profile "Adobe RGB" as the color space and then inside the printer dlog be sure to select "No Color Management". What this does is "fools" ColorSync to avoid an unwanted (and unwarranted) arbitrary color space transform of the printer target..."

(http://forums.adobe.com/thread/501124)

Unfortunately, the problem with this solution is that you can't select 'No Color Management" with the QTR driver.
So it looks like my only avenue is purchasing CS3.
