HP faces backlash for a firmware update (version 20250209) issued for LaserJet MFP M232-M237 models, which allegedly renders these printers inoperable despite using HP-brand toner. Released on March 4, 2023, the update includes typical security updates and bug fixes, but users now report encountering an Error Code 11 and flashing toner lights after the update. Despite efforts like cleaning toner contacts and reinstalling cartridges, many users find their printers unusable, raising significant concerns, particularly from small business owners reliant on these devices for daily operations.
"Insanely frustrating because it's my small business printer and just stopped working out of nowhere[,] and I even replaced the tone[r,] which was a $60 expense."
