I own a OfficeJet Pro L7780 which requires the 36 volt 2.5 amp AC adapter with the special end on it. Many are interchangeable between models so be sure to check which adapter yours will except. And the ampere output of the adapter as some that look similar and have the correct plug type at the printer, only have a 2.0 amp output. This particular model of the HP adapter has an LED indicator on the end that plugs into the printer which makes it nice in the fact that you know when it's on, you have power ask the way through up to the plug in point at the printer. When you need one, you need one. As long as it works and provides the power needed for your printer. You'll be a happy camper.
