Abstract: In a droplet ejection control apparatus according to the invention, a judgment section judges, taking a dot position that is assigned by a predetermined nozzle (incorrect ejection position) as a reference, whether or not a printing state is such that a second proximity dot lands earlier than a first proximity dot.
