Hi Andrew
I'd be interested to know what you found. I've always used Roy Harrington's Print Tool to print patches w/o color management.
Getting back after some testing...
First yes, I have Roy's Print Tool too, it's great for printing without color management.
As to Qimage, I did some output testing and cut to the chase, I just purchased a copy. It's really nice and the output sharpening is impressive. Qimage will also print targets as it has a no color management mode.
