Ken,
I underestimated your powers of analysis. I stand corrected... or sit as the case may be.

If the postscript print driver were taking "grayscale" images and printing it with black only, then this image also should have only had black toner. But that image had all four color toners to make the grayscale, so the conclusion that the driver expects CMYK images I believe is correct.

He sent a CMYK file that had zero CMY values and a grayscale on the black if I remember rightly. My guess is that most office copiers would just ignore the CMY and treat the black as if it was a greyscale image.
