Abstract: A system for interactively selecting and activating groups of electrically powered devices such as computer and computer peripheral devices. A preferred system includes computer and computer peripheral devices, an interactive video display and a controller. The computer and computer peripheral devices include a printer and at least two computers, each of the computers including a printer port. The computers include a controller interface computer which executes a controller interface software module to generate control signals including user interface control signals. The video display receives the user interface control signals and, in response to the signals, interactively prompts a user to provide user inputs to the controller interface computer. The user inputs include a designation of a selected group of devices from the plurality of electrically powered devices.
