Abstract: A method is disclosed. The method may involve obtaining information indicative of a number of printing passes of a print head to print a swath on a printable medium. The method may comprise determining that the print head is to perform a particular printing pass which is one of: a printing pass during which an amount of print agent to be deposited from nozzles of the print head differs, by an amount that exceeds a defined threshold, from an amount of print agent to be deposited from the nozzles during a printing pass immediately preceding said particular printing pass; and a printing pass to print a swath which is the first of a plurality of adjacent swaths in which each swath has an area coverage exceeding a defined threshold. The method may comprise preparing, based on said obtained information, a schedule for a nozzle spitting procedure to commence before the print head performs the particular printing pass.
