Abstract

An ink jet droplet generator 1 including an acoustic chamber 2 for squirting ink under pressure through a nozzle aperture 3 toward a printing medium. A typical Raleigh-type ink jet printer comprises a piezoelectric crystal driver 4 for pro-ducing pressure waves in the ink. These waves insure that ink droplets break off from the ink column 5 at a specific distance from the generator to form uniform sized ink droplets.
