where N is an integer greater than one; each ejector ejecting onto the recording medium at most one
drop of ink during each actuation interval of the spot cycle forming a spot of ink having up to N

a memory, coupled to said first printhead and said second printhead, for specifying a set of
ejectors from said printhead for a first actuation interval of the spot cycle and a set of ejectors from
said second printhead for a second actuation interval of the spot cycle, with the first actuation
interval of the spot cycle of said first printhead being out of phase with the second actuation interval
of the spot cycle of said second printhead by an integral number of actuation intervals less than N;
