Abstract (en)
An acoustic ink printhead employing a flowing stream of ink past the ejectors to maintain a fresh ink supply at the ejector sites. An aperatured plate-like member aligned with the ejector sites suppresses sideways droplet ejection components. A secondary pressure field using acoustic pulses or a pulsed heater provides dynamic liquid level control in addition to controlled switching of the ink droplets. <IMAGE>
