This money saving four pack contains one each of the four colour toners for your printer, helping you buy each high capacity HP 203x cartridge and save money on buying them individually. Each toner is manufactured by HP specifically for your printer and, being the high capacity cartridges, last far longer than your normal toners, giving a huge 2,500 page yield in the cyan, magenta and yellow and 3,200 pages in the black.
High capacity simply means each HP 203X cartridge contains more toner for your prints, they're still the same size cartridge and install into your printer as normal. They contain the same high quality toner you expect from HP too, providing clear, professional prints perfect for work and presentation documents.
