I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand the HP printer isn't printing color anymore,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Have you ensured genuine cartridges are being used?
Did you reseat or replace any low or empty cartridges?
While you respond to that, here's what I recommend for you:
Step 1: Use genuine HP cartridges
HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to hp.com/go/anticounterfeit.
Step 2: Check the estimated ink levels
Check estimated ink levels to see if any ink cartridges are critically low or empty.
Step 3: Replace any low or empty cartridges
Replace any critically low or empty ink cartridges, and then try to print again. Skip this step if all ink cartridges display full ink levels.
