Abstract
A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a printhead to eject a print fluid through an opening of a carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system is to flow air through the carrier plate to the movable support surface via a port through the carrier plate on an inboard side the carrier plate and to control a flow rate of the air flowed through the port based on a size of a print medium transported by the media transport device.
