If you're printing B&W using color inks, converting back to RGB allows you
to use the color balance sliders to adjust the overall tone. Also, I've
found that the Epson 2200 printed with a horrible color cast, if I printed a
grayscale image with color inks, but printed correctly if I converted to RGB
first--but I suspect that was just a bug in that particular driver version.

The image will automatically be reduced to 8bpc on the way to the printer
driver.
