Rendering Intent is a term to describe how colors both inside and outside the gamut of the printer are 'mapped' into the colors available on the printer (as described by the printer's ICC profile). The range of colors that a printer or monitor can show or that a scanner or digital camera can capture varies from device to device. It also varies with the whiteness of the paper, in the case of a printer.
