An anonymous reader quotes some harsh allegations from Myce.com: Thousands of HP printers around the world started to show error messages on the same day, the 13th of September… HP printers with non-HP cartridges started to show the error message, “One or more cartridges appear to be damaged. Remove them and replace them with new cartridges”… When [Dutch online retailer 123ink] emailed their customers asking them if they wanted to check if their printer also had issues, they received replies from more than 1, 000 customers confirming the issue… Consumers who complained to HP were told the error was caused by using non-HP cartridges. A day later HP withdrew that statement and explained the issues were a side effect of a firmware update, [but] printers without any internet access started to reject non-HP cartridges. Therefore it’s very unlikely that a firmware update caused the issues and the only other logical explanation is that HP programmed a date in its firmware on which non-HP cartridges would no longer be accepted. “Printer worked fine for nine months, ” complains one of many angry users on HP’s web site. “Then on 9/13 HP uploaded without my permission a firmware update that caused a message ‘damaged cartridge’ for all my cartridges and then it refused to print.” Read more of this story at Slashdot.
