Anyone print on adhesive vinyl?

Not to hijack the thread, but how does that work? It looks like the 800PS is a just a standard printers. Does it require special ink? Where do you purchase the vinyl stock? I'm just curious because I have access to an HP DJ 500 (24") plotter at work but it is basically just a glorified Ink Jet Printer. It works well, but I've never thought of printing on vinyl with it.
