Hi
Thank you for joining HP Forums.
This is a great place to get support, find answers
I understand that the printer is not printing in color.
No worries, I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Are you using genuine HP cartridge?
Is copy in color working fine?
However, click here for the troubleshooting steps.
Do get back to me as I have a few more tricks up my sleeve. Said that, if I have helped you resolve the issue.
Feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon followed by clicking on 'Accepted as Solution'
Have a great day Ahead!
