Prints OK, but seems to be incompatible with printer software - This item works OK (I can print documents), however the software of my HP Officejet 7210 all-in-one does not recoginze the cartridge, and as such it keeps showing annoying messages on its screen to install a black cartridge (it is already installed!). This also means that I cannot check the levels of ink remaining from the printer s utilities. The printing speed seems to be slower as well. The only thing I have done is take out the old used cartridge and install this one, so I can t see why it is not recognized by the printer.I give it 2 stars instead of 1 as I can still print however.
