"Black ink only" is a setting that people tend to use in order to
conserve the color carts when the printer is set up for general use.
If you set the printer to 'black and white' but not 'black ink only',
it will still use the color tanks in order to reproduce images in a
decent greyscale. If you use 'black ink only', it will force the
printer to NEVER use the color cartridges for greyscale, instead the
greyscale will be a dithered image created out of tiny dots of black
ink. If the image itself is solid black, then setting black ink only
should not have any effect on the output. For my Epson R340, it
doesn't matter what quality setting the printer is in, if the image
is solid black, then the printer only uses black ink. 'Black ink
only' only has an effect on greyscale prints. It is not selectable for
photo printing because dithered black is hardly photo quality and
would be a waste of paper and ink. I just find it highly unlikely that
any modern printer would try to create black out of triple colors.
