I bought a printer in April 24 and used instant ink for a while. After it got too expensive I bought other brand cartridges - which HP have disabled me from using. This is such a scam 😮 I am totally shocked that a company is able to use software to stop me choosing what ink cartridges I want to use in MY printer that I paid for in full. Oh and by the way if you buy HP ink cartridges for your printer (which will work) they don't fill them all the way up, so they can continue to rip you off. I think legal action should be taken against them. I will never buy anything from HP again. Please avoid at all costs and save yourself a lot of stress!!!!!!!!!¡?
