Although the HP 659A black toner cartridge offers less than half the pages of the 659X also available, the price has been reduced noticeably to compensate. The Hewlett Packard W2010A is the choice for those offices that do not use their printer a huge amount and it would take them a good while to gt through its estimated 16,000 prints.Compatible with several LaserJet Enterprise M776 multifunction laser printers, the HP W2010A is only used in high end machines. This Hewlett Packard 659A cartridge comes filled with genuine black toner powder, so each print comes with a quality that we have all come to associate with the manufacturer.
