Printing on paper is ONLY possible as CMYK. RGB and CMYK are kind of opposite approaches (additive vs. subtractive) to color rendition. Conversion from RGB must be done with quality professional software (e.g. Photoshop) if the color balance is to be reasonably preserved. Some scanners offer the conversion in their proprietary software, but to be sure, use Photoshop or something equivalent. And as Tim says, CMYK has four channels.
