HP recommends that you use only genuine HP ink and toner cartridges. And HP's cartridge-protection measures mean your HP printer won't be able to recognize generic ink cartridges, as they're incompatible with HP printers. There are some workarounds. However, that may disable HP's cartridge protection. If your printer isn't internet-enabled, go to the Settings menu on your printer and look for Disable HP Cartridge Protection. Select this option, then select Disable. If your printer is internet-enabled and you're using a Windows PC, navigate to Devices and Printers, select your printer, and open its Settings. Select Estimated Ink Levels to open the HP Toolbox. Click Cartridge Protection, then choose Disable HP Cartridge Protection.
