Abstract
A system that incorporates teachings of the present disclosure may include, for example, an apparatus having a tube with an ingress opening to receive a liquid, and an egress opening to release the liquid, a conductor positioned in a conduit of the tube, the conductor and the conduit having dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening, and a power supply coupled to the conductor to apply a charge to the liquid to overcome the surface tension and form at the egress opening a single jet stream of the liquid applicable on a substrate to create a pattern. The single jet stream can be controllable in part by a viscosity of the liquid. Additional embodiments are disclosed.
