The ejection of droplets in an ink jet printer is accompanied by the generation of capillary waves that spread out radially from the central region where the drops are ejected. These capillary waves interfere with the ejection of succeeding droplets. In order to suppress these capillary waves, the pressure in the pool of liquid feeding the printer is varied periodically at twice the maximum repetition rate of droplet ejection. |
