Halftone Mode slows down the transmission speed and may increase your
communication costs, especially if you use the Error Diffusion process. Higher
resolutions also do this. This is because these settings create larger amounts of
data to be sent. Messages are transmitted faster if you use the standard
resolution setting, and keep Halftone off.
