description A drug delivery device and method of using the device. The device includes a cartridge body; a fluid outlet nozzle attached to the cartridge body; and a cartridge disposed in the cartridge body. A fluid ejection head is attached to the cartridge and is in fluid flow communication with the fluid outlet nozzle. The cartridge contains a liquid pharmaceutical drug. A logic board is disposed in cartridge body and is electrically connected to the ejection head on the ejection cartridge. A processor is disposed on the logic board or on the fluid ejection head for executing a control algorithm to control the ejection head to modify plume characteristics of fluid ejected from the ejection head by controlling one or more operating parameters selected from (a) a number of fluid ejectors fired per ejection burst, (b) a position of fluid ejectors fired per ejection burst, and (c) both (a) and (b).
