Zusammenfassung:A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper, transported through a deposition region. The media transport device holds the print media against a movable support surface, such as a belt, by vacuum suction through holes in the media transport device and transports the print media though the deposition region. The airflow control system comprises one or more valves that are actuatable between an open state and a closed state, each valve blocking a subset of the holes in the closed state. The airflow control system also comprises one or more actuators to actuate the valve(s). The actuator(s) selectively actuate the valve(s) between the open and closed states based on a position of an inter-media zone between adjacent print media.
