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, the holes arranged in columns extending in the process direction and in rows extending in a cross-process direction perpendicular to the process direction; and
an airflow control system comprising:
a damper that is moveable in the cross-process direction between a deployed configuration and an undeployed configuration, the damper blocking at least one row of the holes in the deployed configuration and not blocking the at least one row of the holes in the undeployed configuration; and
an actuator operably coupled to the damper and configured to move the damper between the undeployed configuration and the deployed configuration.
