It's great to have you back and your patience is greatly appreciated.
I'm glad to hear you found the printer partially working however, you are still having issues printing in colour from your PC.
This looks like a Operating system issue, I would suggest you go ahead and follow the steps from the previous post to create a new user account and then try to install the printer software.
Let me know how it goes for further assistance.
Waiting for your response!
Regards,
