The selection of gamma space will not effect the printed image per se.
However, if your concern is to obtain an accurate preview on screen of what
the image will look like when printed to a particular media (and you are not
using a colour managed workflow) you are much better off following the print
preview methodologies that have been highlighted in this forum in the past ­
particularly by Carl Schofield and others.  Here is an old post from Carl:

<<I recently discovered (stumbled across) a way to create standard icc
profiles that can be used for soft-proofing QTR prints in Photoshop. 
I've put a sample soft-proof profile that was created from an icc
profile for a QTR sepia curve that I use quite often in an archive on
my filesharing site.  Just drop the proof profile (sepia1.psf) in the
folder Library>Application Support>Adobe>Color>Proofing and follow the
illustrated instructions for using the soft-proof in the read-me file
that is also in the archive.  You don't need to be using or have QTR
installed to just see how any RGB or grayscale image you have will
actually look if it were printed with QTR and the sepia curve I'm
using. The read-me also has instructions for creating the icc profiles
if you want to make your own.  This can be applied to any inkset/paper
and probably with quad workflows other than QTR as well.  One of the
nice things about using standard icc soft-proof profiles is that you
can work up your image for printing in any mode (full RGB color or
grayscale) and get a preview of the printed results as you do RGB to
grayscale conversions, curve adjustments, etc. with the soft-proof
turned on.

The softproof archive with the profile and tutorial is in the QTR
Soft-proof folder at:

FYI My Apple Cinema HD display is calibrated with Gray Gamma 2.2 and I use
this as my gray work space in PS CS.

Hi John

The gamma you set can be from 1.8-2.4.  However, the purpose of the
gamma is to match the monitor's image display with the printed
image.  Currently, I am using a grayscale gamma of 2.0 but I am
printing through a lab service that uses Studioprint.  You might want
to leave a higher gamma because gloss papers seem to have a higher
DMAX than matte papers.
