Randy, having used the B9180 fairly extensively it is my experience 
that the HP inkset really needs GO to avoid GD on all PK papers when 
just using black and gray inks. GD does not show up using the full 
color inkset to print BW but does so badly when just using the grays. I 
guess that is why the wide carriage HP printers have GO on board.
