Abstract: A printer is configured for printing with conductive ink for applying a conductive pattern to a surface including a wheeling structure for moving the printer over the surface and a transfer unit for applying a layer of electrically conductive ink to the surface. To provide accurate printing with the ability to obtain fine tolerances, the transfer unit has a printing drum rotatable about a printing drum axis and defining a printing drum periphery moving between a first zone and a second zone by rotation of the printing drum. The printing drum periphery, in the first zone, receives the conductive ink and in the second zone transfers the ink to the surface.
