An electronic printer is described that puts dots of ink on paper using the magnetic properties of some superconducting materials. The property is that the superconductor will not tolerate a magnetic field. When subjected to a magnetic field, the superconductor will try to escape from the field. This effect is used to propel particles of superconducting ink towards the paper to be printed on. The superconducting ink is applied to a printhead that has an array of tiny solenoids. When a magnetic field is created by a current pulse applied to each solenoid, the superconducting ink will be expelled from the solenoid and land on the paper, strategically located in front .of the array. The printer will need a mechanism to control the current pulses, a way to supply ink to the printhead, and a paper motion system.
