Abstract
An example of a printing apparatus comprising a scanning printhead and a controller is disclosed. The scanning printhead comprises a plurality of nozzles to print using a mask comprising a ramp area and non-ramp area. A first subset of nozzles of the plurality of nozzles is assigned to the ramp area and the second subset of nozzles of the plurality of nozzles is assigned to the non-ramp area. The controller is to calculate a number of spits of a nozzle from the second subset of nozzles for a pass. The controller is also to calculate a number of spits of a nozzle from the first subset of nozzles for the pass based on the number of spits of the nozzle from the second subset of nozzles. The controller is further to instruct the nozzle from the first subset of nozzles to eject online an amount of a composition on a service zone based on the number of spits of the first subset of nozzles.
