An inkjet printing system, comprising: one or more inkjet printheads for printing drops of ink onto a receiver medium, and an acoustic air impingement drying system positioned in proximity to at least one of the inkjet printheads. The acoustic air impingement drying system includes: an airflow source providing a supply flow rate; an acoustic resonant chamber having an inlet slot that receives air from the airflow source and an outlet slot that directs air onto the receiver medium; an exhaust air channel for removing the air directed onto the receiver medium by the acoustic resonant chamber; a blower for pulling air through the exhaust air channel at an exhaust flow rate; and a blower controller that controls the supply flow rate and the exhaust flow rate, wherein the exhaust flow rate is controlled to match the supply flow rate to within 1%, or to exceed the supply flow rate.
