"The device shown has been blocked by printer firmware because it contains non-HOP chips," messages displayed on the u/grhhull read printer screen. Instead of displaying bypassable messages showing HPs can't guarantee the quality of their prints, u/grhhull says their printers won't use third-party ink tapes at all. One of the Reddit users, u/grhhull, said they could no longer use third-party ink tapes with their HP printer. However, it appears that HP is expanding its dynamic security policy to more devices that used to be compatible with non-HP tapes. This means prohibiting the use of ink or toner tapes that do not contain "new or recycled HP chips or electronic circuits" on some printers, something the HP has faced with criticism and some class action lawsuits.

Introduced for the first time in 2016, dynamical security is part of the HP cassette authentication process that the company says should "protect the quality of our customers' experience, maintain the integrity of our printing system, and protect our intellectual property." Various reports are spread across Reddit, Twitter, and a community HP forum showing that the latest printer firmware updates hinder the use of non-HP ink as part of the company's strict "dynamic security" policy, as reported first by Ars Technica.

JAKARTA World printer manufacturers, HPs again prevent more customers from using third-party ink with their printers.
