I actually figured out a really good process for transferring printed images.  I print the image at work (Not inkjet but the toner kind of printer).  Then tape it to the leather and use a cloth dampened with Xylene (available at home depot).  Then I dab the image with it a few times letting it dry in between.  I also rub with a spoon and even cover with a scrap piece of leather and cobble hammer the image in.  With practice it looks like it was printed on there!
