An apparatus including a dot matrix transfer head that includes an impact wire housing. A plurality of impact wires are disposed within the impact wire housing and extend out of the impact wire housing. A splaying element attached to a bottom surface of the impact wire housing. The plurality of impact wires extend into and through the splaying element. A guide head attached to a bottom surface of the splaying element. The guide head includes multiple holes that arrange the plurality of impact wires in a matrix configuration. The splaying element is designed to direct the plurality of impact wires toward the multiple holes in the guide head.

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.
