An ink-jet printhead and a method of manufacturing the same include a substrate on which a heater and a passivation layer protecting the heater are formed, a passage plate on which an ink chamber corresponding to the heater and an ink passage connected to the ink chamber are formed, and a nozzle plate in which an orifice corresponding to the ink chamber is formed. Because the user equipment devices in the home network may have different capabilities, the user may wish to deliver different types and amount of content, different amounts of data, and different versions of interactive applications to the user equipment devices in the home network. Since replacement of the main fan unit would involve a prohibitively large fan due to starting currents, the larger component that would have multiple cooling purposes is replaced with smaller single function electrical components.
