“Insanely frustrating”: HP printers stop working with HP toner due to update – Ars Technica

HP is facing criticism after a recent firmware update, version 20250209, released on March 4 for its LaserJet MFP M232-M237 models, reportedly caused issues with printers using HP-brand toner. Users have experienced problems such as Error Code 11 and flashing toner lights, rendering their printers unable to print despite using official HP toner. This has caused significant inconvenience, particularly for small business owners who rely on these printers for their operations.

The update was intended to include security enhancements, regulatory updates, and general improvements. However, there was no mention of changes affecting toner usage. This incident adds to HP’s controversial history of firmware updates that disrupt printer functionality, including a previous instance in May 2023 where an update caused HP OfficeJet printers to malfunction.

The ongoing issues have led some customers to switch to other brands, such as Brother, despite similar accusations against Brother for firmware updates affecting third-party toner usage. HP has not yet provided detailed comments on the scope of the problem or solutions for affected customers. This situation underscores ongoing customer frustrations with printer manufacturers over firmware updates and printer functionality.
