I've used Gray Gamma 2.2 for some time now in a Windows environment.  My workflow involves saving a "printing only" file to the desktop that has been re-sized to whatever I want and also has a curve applied to it to adjust for the differences between the linear QTR space and the non-linear GG 2.2 space.  

See http://www.paulroark.com/BW-Info/Eb1400.pdf at page 10 for a graph that illustrates the different spaces' characteristic curves.  The Photoshop *.acv curve I use for the adjustment is in the following Zip file:

The PDF at http://www.paulroark.com/BW-Info/Eb1400.pdf includes my basic (Windows) QTR ICC and RIP workflows.  I used the 1400 and this modified Eboni-6 (with HP PK black only option) at the Golden Trout Photo Workshop this year.
