Abstract
A printing system comprises an ink deposition assembly and a media transport assembly. The ink deposition assembly comprises a printhead arranged to eject a print fluid to a deposition region of the ink deposition assembly. The media transport assembly comprises a vacuum source and a movable support surface. The movable support surface comprises valves having holes through the media support surface. The media transport assembly is configured to hold one or more print media against the movable support surface by vacuum suction communicated from the vacuum source through valves. The valves are each configured to transition between a closed state in which airflow through the hole of the respective valve is prevented and an open state in which airflow through the hole of the respective valve is allowed.
