Oh I see, you're not printing the whole thing in one go, but you're printing each of the images individually and then will be manually gluing them to a bristol board?

Are the images all different sizes on the virtual bristol board then? I.e. when you end up with your stack of printed images, they'll all be different sizes from big to small?

If that's the case, then I'm not sure how to get to the next step, other than measuring the size of each image in Photoshop somehow (ruler guidelines I guess) and then creating a new PSD file for each image and setting the physical size to the desired size (i.e. if one image measures 2" x 3" then create a new file and set the physical size to 2" x 3" and then paste the image into that and save it, then give the group of files to be printed).

Or it might be easier (and cheaper) to actually get the bristol board printed as you've designed it in one shot, there's places that should do that (though don't know the cost).
