I have an inkjet printer , HP office jet pro 6970 . Good printer too . I've just cancelled my subscription to HP direct ink .(it's over 12 months old now so out of warranty . I can't believe that HP would be so petty and vindictive . After clicking cancel I got the message "do you really want to cancel ? You do realise that when this month's subscription ends , you will be charged another month's rent to cancel , and also you won't be able to use the ink that's left in your printer after this time ". I' m not that bothered because I'll use my laser printer , so I won't be stuck , Really I only use the inkjet for colour jobs that the laser isn't just up to - photos etc. I wouldn't mind betting that when I buy my own cartridges , I'll get a nag - message about using spurious cartridges too . If I'd ever contemplated going back on to HP's scheme , I certainly wouldn't now . F.U. Mr. Hewlett , and Mr Packard too ! Now to Google "ink cartridges" ! I notice that an old black cartridge has a little embedded chip , so I'll need to check this with the new supplier .
