A report by Which? suggests that Hewlett-Packard have pre-programmed their printers to reject cheaper generic cartridges and to give an error message. Which?’s report from September, and updates, are shown below.
We believe this gores beyond the list of printers HP have identified, and consider that HP’s action may breach EU and UK consumer law. if this is the case, a class action or supercomplaint may be possible.
