You can do this very acceftively using Photoshop, or any ICC aware application that lets you convert from CMYK to RGB during the Print Process. Applications that spring to mind are Illustrator 9/10, Indesign 2, Photoshop 5/6/7.

Its to do with how printer drivers interact with the system. Even the Epson 10600 driver is RGB based. I wouldn't call that printer a consumer device. > By printing from a CMYK image file you are limiting the range (aka gamut) of > colours that your image can contain.

If you are generating the work yourself and are using your printer as the final device, then use a good RGB colour range such as Adobe RGB (1998) as this will give you an optimum range of colour to work with.
