What should I do before using my HP LaserJet P2055 for the first time?

Before first use, carefully remove all packing materials, tapes, and protective films from the printer, then install the included toner cartridge by opening the top cover, shaking the cartridge to distribute toner evenly, removing protective seals, and inserting it until it clicks into place. Load paper into the main input tray, connect the power cable to a grounded outlet, and install the appropriate printer drivers from the HP support website.
