QTR-Quadtone RIP

Hello, I'm new to this group, and new to the Quad Tone Rip.
Up until now I've been printing all of my gray scale images using the Epson ABW driver on my Epson 3800 along with ABW ICC profiles from Eric Chan in Lightroom.

I know that QTR wants gray scale images with a gamma of 2.2,  but Lightroom uses Prophoto color space with a gamma of 1.8
I'd like to hear what others on this list are doing in regards to this issue.

The fact that I'm only two days into the QTR I have many questions, but I'll start with this one first, thanks in advance.

I'm relatively new to QTR myself, but I work up my images in Photoshop,
Prophoto space, in color, even though they are destined to be monotone
images (I have my own workflow for B&W). I don't convert them to B&W and
have been printing them straight to QTR with carbon inks in a dedicated
printer and getting fantastic results so far. Still some work to do yet,
butŠ
I tried ABW and it was a joke compared to what you can do with QTR and full
B&W inks.
You do want Gamma to be 2.2 throughout your workflow. Otherwise, the print
will be farther off from what you see on the screen than what it needs to
be. It won't do any damage that I am aware of, you will just not have
anything close to WYSIWYG.

I'd like to hear what others on this list are doing in regards to this
issue.

I export (RGB PSD) to Photoshop Elements and then export to TIF Grayscale
(2.2 gamma) from there.

I\u02bbve been printing gray gamma 2.2 directly from Lightroom 4 to my Quad4880 printer, and seeing fairly good screen-to-print consistency, both with Cone profiles and with some Eboni profiles I made. I choose "printer manages color" in the print settings. (Of course, I might just have really low expectations.) 

Sounds like Photoshop CS6 is a disaster for B&W QTR printing. You might find this link helful:
