HP is backtracking on a firmware update that recently blocked some printers from using third-party ink cartridges. Some users reported that the update sometimes mistakenly marked legitimate ink as fake, so HP’s CEO Jon Flaxman wrote today that the company will issue a new update to turn off the DRM.

HP also clarified that third-party cartridges still work with the original update, so long as they’re built with HP security chips — aka HP is getting a cut of their business. The first mandatory update took effect on September 13th and forced printers to display "damaged cartridge" whenever a bad third-party cartridge was loaded. Following its activation, at least one company vowed to create new chips that could subvert the security check. It looks like that won’t be needed for now.
