I did examine the print with a very strong loupe and there was only black
toner. The other image I printed the same way was an RGB grayscale
(gradated from 0 - 255) with R=G=B. 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.
