A non-direct contact ink-jet style printer is disclosed herein, which uses a superfluid cryogenic fluid such as superfluid helium as the ink medium. Superfluid helium is non-viscous thus enabling the print head of the present invention to print nanoscale characters onto a substrate. In one exemplary embodiment, dopants are injected into the ink droplets to load the droplets with dopants, which then deliver the dopants onto the substrate. Multiple nozzles and different dopants may be used with the embodiments disclosed herein to provide different outputs on the substrate. Spent or un-used droplets and dopants may be educted away and discarded or scrubbed for reuse. Methods for printing using superfluid helium are also discussed herein.
