It’s a never ending story, HP once again has forced a firmware update unbe-known to its users. The end result being that these cartridges are no longer recognised by the printer.
The affected cartridges are HP 950 & 951 Set, HP 932 & 933 range.
For now we have stopped selling these cartridges but rest assured a solution is being worked on and we hope to have these cartridges back on sale soon.
We do advise customers who wish to continue using compatibles to stop automatic updates. You can find instructions on how to achieve this by following this link.
