The HP 953 cartridges are part of the OfficeJet Pro series printers. This doesn't necessarily mean that every OfficeJet Pro printer supports the 953 cartridge line. If in doubt, it's good that you check this before purchasing them. This saves a lot of hassle when it turns out that they're not the right cartridges. The suitable printers are listed in the product description of the cartridges. The 953 line consists of separate cartridges and combo packs. This allows you to choose what suits you best.
