Sometimes there are delays caused by suppliers not keeping pace with Apple changes. If there is no formal software update you will have to go to the HP official site.
Their instructions should help you identify what you need.
If it's any help, I recently had cause to use them and unlike most support sites I managed to update my HP C6250 all in one software with little trouble.
