“HP is preventing more customers from using third-party ink with their printers. Numerous reports scattered across Reddit, Twitter, and the HP community forum suggest that a recent printer firmware update is blocking the use of non-HP ink as part of the company’s stringent ‘dynamic security’ policy, as first reported by Ars Technica. … In 2020, HP reached a $1.5 million settlement with customers in the US as part of a class-action lawsuit that claimed the company’s firmware acted as ‘malware’ by ‘adding, deleting or altering code, diminishing the capabilities of HP printers, and rendering the competitors’ supply cartridges incompatible with HP printers.’ The company also paid out millions to customers affected by dynamic security in the European Union and Australia after barring users from installing more affordable third-party ink cartridges.” (03/11/23)
