Hi Tim,
See if you can find an ALPS 5000. They are discontinued, so ebay is about the only source. Microscale sells the decal paper to use in it, and it is "laser paper". Then make sure you have all the color cartridges you need for at least the decal you are going to print first. The 5000 carries 7 cartridges at a time (one slot has to be open so the printer can "exchange" carts. while it's printing. You will need to have some fairly recent coreldraw program (and learn how to use it if you don't already) to make your artwork. Make your color "layers", and use the "single ink" function to underlay all the decal with white as the first layer. All the images on that layer (1st one) will need t be any color that the printer can "see'. It cannot "see" white. Then print each layer. As you hit "print", go to the settings and use "overlay" under the the selections. Other wise, the printer will spit the paper out when it prints and you can never get it to register correctly again. There is a "project manager" feature which will automatically go from layer to layer, but i have never used it. The ALPS 5000 is the "sharpest" printer you can get. It prints at 2400dpi dots per inch). Also, use "cardboard" (not "laser paper") for the setting when you go to print. Otherwise you will burn up the anti curl motor. Done correctly, you can print an object that is totally clear that you will need an optivisor to read any lettering. Oh, yeah, you will need to use a Windows 98 or older system. There are no drivers available for newer operating systems. But then there is no other printer under a couple thousand dollars that will actually print "WHITE". The are very fragile printers, but I have taken care of mine, been very cautious and it is getting pretty old. The printer alone usually goes for around $300 last time I checked, as long as it's a working one. No service available in North America anymore.
