Wax technology has come a long way. Now the Xerox Colorqube 8880 can go a blazing fast 51 pages a minute and is still super inexpensive for doing color prints.
One of the things to consider if you choose to get a Xerox Colorqube printer is the different quality settings go at vastly different speeds.
Fast Color: Up to 51 ppm
Standard: Up to 30 ppm
Enhanced: Up to 19 ppm
High Resolution: Up to 6 ppm
So if you need to go fast all the time, and have high quality color needs, this would be a bad printer for you. It may go as slow as 6 pages a minute. That is pretty scary slow, but the output looks amazing, so it is all a trade off.
