A system and method for controlling one or more appliances includes a control system where one appliance is in a condition such as having operated at full capacity for a predetermined period of time, and activation signal is sent to a secondary appliance. For example, by transmitting data using radio formats which are different in each band or at each radio frequency, the radio transmission method is made different in each band or at each radio frequency. The printer is operated by a controller PCB located within the housing that is responsive to commands from the computer.
