What about Oki's line of CMYW printers? I received a sample from one when they started the line and it was impressive. The $3400 price tag for a C711WT is a bit pricey for me but if someone wants to go into the decal business that cost is a tax write-off.
I haven't checked capabilities of that specific printed but as you point out, the price makes it out of reach for hobbyists. It might be viable for small businesses. Can it for example just print white? Some laser printers only use white as undercoat for CYM colors.
One thing I did notice with CYM (no K or black) ink jet printers was that solid black color was really a very dark muddy-looking brown. That is because black in those printers is made up of a mixture of CYM inks. Not sure if the same will be true with lCYM laser printers but I suspect it is.
As a hobbyist I often use the Alps' capability of printing metallic inks and the capability to overlay multiple layers of color inks. The CYMW laser printer cannot do any of that. Hopefully with some ink cartridges and a spare printer) squirreled away, I will be capable of printing my own decals for as long as I'm not the hobbies.
