It's thin 11" X 8.5" sheets of self-adhesive plastic film. You can
get them for laser printers and copiers or for inkjet printers. Print
on the sheet like paper, spray a protective coating over it if
necessary, cut then peel off the backing and apply. Bought mine
(opaque white for laser) several years ago from a place called Pearl
Paint but they no longer stock it. A Froogle search indicates a place
called Mister Art having it in stock. Here is a link for laser ready
products, they should also sell inkjet ready equivalents;

A simple plug-n-play setup using drivers from here;

Before getting the above I also bought and evaluated one of these
which just about everyone seems to use and recommend;
