Abstract
An ink jet printing device including a printing head having a nozzle through which ink can be ejected. The head includes an internal chamber ink and ink ejection is caused by internal pressure pulses. The internal chamber is formed in part by a deformable diaphragm which prevents extreme ambient temperature variations from causing damaging liquid pressure fluctuations.
