Rather than implementing a printer as a single set of rendering parameters, a printer can be implemented as a meta-printer that comprises one or more virtual printers. A shut-in device is positioned in the casing so as to be below the surface of the formation. Each pulse may be chosen to be less than about nanoseconds, while a \u201crest period\u201d between pulses typically is chosen to be on the order of about a hundred nanoseconds or greater. The first dummy region is formed under the conductor pattern so the grooves are not formed under the conductor pattern. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.
