Digital BW, The Print

Just to make sure things aren't getting confused...David, you're talking
about the desktop HPs, right? John I think was talking about the Z series
and from the beginning HP has said that whether the driver is set to color
or grayscale, equal RGB values are printed with black and gray inks
exclusively. It's been a while since I pulled out the loupe, but some test
prints I did when the printer came out showed no difference in grayscale
files printed in either color or mono driver modes and no difference between
a grayscale print and a grayscale portion (equal RGB) of an otherwise color
image. The Canon IPF driver is a different story, and indeed the color
driver adds CMYs to a grayscale image. The grayscale driver supposedly does
not.
