The high capacity HP 973X black ink cartridge offers more than twice as many pages as the similarly compatible 913A alternative. This makes the Hewlett Packard L0S07AE great value as a genuine cartridge, and an absolute steal as a remanufactured alternative!With is substantial size and 10,000 page printing yield, you would be forgiven for thinking that the HP 973X black ink cartridge is in fact a toner cartridge. We love that Hewlett Packard have combined the economy of print of a toner with the print quality of an ink cartridge, and are very proud of our remanufactured version of the L0S07AE.
