I had the same issue with my HP printer not printing black, and calibrating the printhead did the trick! It was easy to do through the maintenance menu, but if you’re not familiar with the process, getting expert help is definitely the way to go. By the way, I was exploring some [Three D Printing Riyadh](https://ksa3d.com/services/3d-printing/) options recently, and it’s amazing how quickly 3D tech is evolving here too!
