Digital BW, The Print

Jerry - a suggestion for why this may be the case...

When printing dark blacks or greys, I believe the Epson driver uses all four
colours CMYK (don't know what it does with the 'photo' colours  on a Photo
printer... but this would suggest that 'blacks will end up getting printed
with all three greys + black on top of each other... Piezo driver will print
Black only, or black + darkest grey.

Just a guess.
