This is a 4-year HP support contract, not a physical product — specifically Next Business Day (NBD) hardware support with Defective Media Retention (DMR) for HP's LaserJet Enterprise M830 multifunction printer. NBD means a technician or replacement part arrives by the next business day after a fault is logged, while DMR lets the customer keep any failed hard drive or storage media rather than returning it to HP — a data-security requirement for many businesses printing sensitive documents. This SKU only covers the service itself; it must be attached to an already-owned or separately purchased M830 MFP unit rather than including the printer.
