Abstract: In some examples, a carriage for a printing system includes a printhead, a conduit to carry a cooling airflow to the printhead, a return chamber to receive a heated exhaust airflow produced from heating of the cooling airflow by the printhead, and a seal between the printhead and the return chamber to prevent the heated airflow from flowing to a location below the printhead.
