When I bought this desk top, I also got the ALPS MD1300, specificly because it can print white (and silver and gold). I usually set up everything on the laptop and print black, to proof the sheet, then scan to the Alps. I keep a "black" label on the white ribbon so I don't have to mess around with settings. So far, the decal have been really good. I don't know about dry transfers
though. The print has to be mirror image, it has to release from the backing, and there has to be an adhesive to hold the letters on the model surface. I would imagine that mirror image can be done with a photo or drawing program, and the backing might not be too hard to find, but the application of adhesive could be tricky enough to rule out home use.
