A printing cartridge ( 1230 ) includes a housing ( 1231 ). An array of switch actuators ( 1232 ) is positioned on the housing. The array of switch actuators represents data relating to at least one of: a serial number of the cartridge, a media and a media colorant so that when a switch array ( 1236 ) is actuated by the array of switch actuators, a signal carrying such data can be generated.
