I just posted a poor review of the printer that's related this very question you've asked. HP just recently (in the last few months) provided printer software updates to all printers, under a "security update" banner. Unfortunately, I had non-HP branded ink (A-MAZING ink from Amazon, for $50!) and after the update, my printer completely locked up with an "ink supply error" message. I received a wonderful message form the ink supplier on Amazon offering a workaround, but it seems HP has thought of everything and has made it VERY VERY difficult to install any previous software version. My printer is still locked up, a month later. They actually took the previous software version off of their website, so people can't revert back. I WOULD NOT BUY an HP printer if I had it to do over again. HP made such a sneaky move, and will not get better. Their branded ink for these printers runs $400-$500 for a full supply... and they obviously don't care about the consumer.
Sorry, there was a problem. Please try again later.Hello. Thanks for your question. We recommend using HP genuine toner for compatibility, security, and consistent print quality.
