HP Envy 5544 won't print in colour despite having brand new ink cartridges.

Hi,

I'm hoping someone can help with this. My HP Envy 5544 won't print in colour, despite having brand new ink cartridges. I have tried everything suggested on previous posts (uninstalling and reinstalling the driver etc.) to no avail. I have spent a long time trying to sort this out so am hoping someone has a solution.

Thanks.
