With the HP 973 cartridges, you can replace the empty cartridges with new ones for HP PageWide Pro and HP PageWide Managed series printers. If you have a printer from this series, check whether your printer model supports the 973 cartridge line. You can read this in the product text of the cartridges. As a result, you no longer doubt whether they fit. You can buy the cartridges separately or as a combo pack. Choose the right cartridges that suit your printing use.
