a fluid jet precision dispensing device is a drop on demand device in which printing or dispensing of the substantially liquid fluid in question is achieved by precisely printing or dispensing in accurately specified locations with or without making a particular image on that which is being printed or dispensed on as such a fluid jet precision dispensing device is in comparison to a continuous precision dispensing device in which a substantially liquid fluid is continuously dispensed an example of a continuous precision dispensing device is a continuous inkjet printing device the fluid jet precision dispensing device precisely prints or dispenses a substantially liquid fluid in that the latter is not substantially or primarily composed of gases such as air examples of such substantially liquid fluids include inks in the case of inkjet printing devices other examples of substantially liquid fluids include drugs cellular products organisms chemicals and fuel which are not substantially or primarily composed of gases such as air and other types of gases therefore while the following description is described in relation to an inkjet printhead structure for ejecting ink onto media embodiments of the present disclosure more generally may pertain to any type of fluid jet precision dispensing device or.
