The HP LaserJet Pro M12a uses one toner: the HP 79A (CF279A), a black cartridge of standard capacity rated at about 1,000 pages. The compatible toner here replaces that part number. The same toner also fits the LaserJet Pro M12w, LaserJet Pro MFP M26a and LaserJet Pro MFP M26nw. Same-day shipping on most orders.
