1. A printing system, comprising:
an ink deposition assembly comprising one or more printheads arranged to eject a print fluid to a deposition region of the ink 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 through holes in the media transport device and transport the print medium along a process direction though the deposition region;
an airflow control system comprising:
a damper that is moveable in a cross-process direction perpendicular to the process direction, the damper arranged to block airflow through a subset of the holes, the subset varying based on a position of the damper; and
an actuator operably coupled to the damper and configured to move the damper; and
a controller configured to cause the actuator to selectively move the damper to change the subset of the holes blocked by the damper based on a size of the print medium
wherein the controller is configured to cause the actuator to move the damper between a first position and a second position, the first position associated with a first size of the print medium and the second position associated with a second size of the print medium.
