1. A printing system, comprising:
a print fluid deposition assembly comprising a printhead module comprising a plurality of printheads configured to eject print fluid to a deposition region of the print fluid deposition assembly;
a media transport device comprising a movable support surface, the media transport device configured to hold a print medium against the movable support surface by vacuum suction and the movable support surface is configured to transport the print medium along a process direction through the deposition region of the print fluid deposition assembly; and
an airflow control system arranged to flow air toward the movable support surface at locations upstream and downstream of the printhead module, wherein upstream and downstream are defined relative to the process direction,
wherein the airflow control system is configured to selectively flow the air based on a location of a print medium transported by the media transport device relative to the printhead module.
