That's exactly what I do for both mine and my wife's non resident license for MI. (I do the same for our Indiana license also.) When it comes up for you to print your license just hit the <Print Screen> key which saves a copy of the web page. Then paste it into Paint and save it to your hard drive. Wala, any time you need to reprint, it's right there. I also put a copy in the boat, both ice shantys, my wallet, and the glove box of the Suburban.
