1. A printer configured for printing with conductive ink for applying a conductive pattern to a surface, the printer comprising 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,
wherein the transfer unit comprises a printing drum being rotatable about a printing drum axis and defining an outer printing drum periphery moving between a first zone and a second zone by rotation of the printing drum,
wherein the printing drum periphery, in the first zone receives the conductive ink and in the second zone transfers the ink to the surface.
