On my MacBook Pro I have changed the operating system recently to Sequoia 15.3.2 and all of a sudden my HP Printer Officejet 6600 started to not print the colours properly. I have new ink cartridges and has as well changed the HP Printer driver to the latest version as well as run the various programs on the printer for cleaning and aligning but, still it gives the same bad result. The colours impacted are for sure the Magenta and Black. What can I do ? Yours, Mikael

@Mikael59, Welcome to HP Support Community. 

 

Thank you for posting your query, I will be glad to help you. 

HP Officejet 6600 e-All-in-One Printer supports up to macOS 15. 

You can however, use Airprint - About AirPrint - Apple Support
AirPrint is a built-in printing solution for Mac, iPhone, and iPad. You can print from most apps that have a print feature.

I hope this helps. 

 

Take care and have a good day.
