maybe you mean uni vs bi directional?, bi is faster, but you have to align dots in the two directions, so very small knocked out graphics can be hard to keep registered
our printer also has the option to do extra passes to increase the ink density. This is useful when you're doing backlit work that looks washed out unless you get the extra density.
hi friend:
First of all, what brand of print head is used and how many is it? the more print head, the faster its printing speed.
