Abstract: A printer includes a printhead assembly, a service station assembly, and a controller. The printhead assembly includes nozzles to eject fluid drops. The nozzles are divided into a least two groups with each group assigned a burst drop count, a post-burst delay, and a burst order. The service station assembly is to receive fluid ejected from the nozzles during spits. The controller is to control a spit of the printhead assembly by ejecting fluid from the nozzles of each group based on the burst drop count, the post-burst delay, and the burst order of each group until a target drop count for the spit is reached.
