This confirms exactly what I suggested before, that the Durabrite inks 
(which are more like acrylic enamel with glue added than the usual 
watery dye and pigment inks every other printer on the market use) 
would indeed be able to print on a nonporous surface like metal. The 
next step, of course, would be for someone to use these inks in a 
R200/300 printer with the CD printing tray, which would allow you to 
print with a straight through path. Or to modify a C-series printer in 
order to create a straight-through path.
