A printer having a media transport with a rigid, air-transmissive platen. A movable air-transmissive flexible web overlays the platen, and a suction device communicates with the platen to draw air through the web and through the platen, such that a sheet of media carried on the web is biased toward the platen. A second movable web below the first web limits air flow through at least a selected portion of the platen other than a portion overlaid by the sheet. The movable web may be a continuous belt, which may have two separate air-blocking regions that are positioned beyond the platen when full airflow is desired, and at least partly registered with the platen to block airflow to peripheral platen portions.
