Abstract
A printer is configured to provide a jet of extraction gas that extracts a printing fluid from a printing nozzle in the presence of an electric field that accelerates the extracted printing fluid toward a printing substrate. The printer is also configured to selectively turn the electric field and the jet of extraction gas off and on to enable printing in gas-extraction mode, an e-assisted gas-extraction mode, or an e-jet mode. The jet of gas can be provided by a second nozzle concentric with the printing nozzle. A third nozzle can discharge a focusing gas around the extracted printing fluid.
