One of the nice things about the product is the quality of B&W prints since they use a mode to eliminate the yellow ink and supply quite good profiles for this mode of printing. Since it bypasses the Epson driver all together, a lot of the OSX/Epson print issues vanish. The supplied color profiles look good (I make my own but I suspect most users without this expensive hardware and software will be quite happy with the color). This and ImagePrint (much more expensive) are both nice for the user who wants to print the best possible image quality or for those that want to deal with vector files.
