An ink jet printing scheme which utilizes drop-on-demand (DOD) technique, and which solves two major problems faced when designing asynchronous, multinozzle DOD devices. These problems are, first, compact design of individual ink chambers and piezoelectric (PZT) drives for the different nozzles in an array and, second, close spacing between nozzles required for high print quality (high resolution).
