This dual pack of cartridges provides great value for money for those looking for genuine HP toner for their LaserJet printer (see below for compatibility). Of course buying a pack of two cartridges not only makes sense from a cost saving point of view but also means you will have a spare cartridge on hand should the inevitable happen and first cartridge runs out in the midst of printing an urgent document. Official HP product This genuine toner cartridge will deliver professional level results allowing you to create eye catching documents and reports with crisp, finely detailed text and images. With unmatched consistency these results will be replicated from the first page to the last; something which ‘compatible’ products from other manufacturers cannot match. Page yield Each HP78A cartridge has a duty cycle of 2100 pages giving a combined yield of over 4000 pages. Ideal for schools, businesses and home users. Free to recycle We all like to do our bit for the environment and recycling these cartridges is easy thanks to HP’s free end of life recycling scheme. Full details on how to recycle your used cartridges are included in the box.
