Hello, bobmax!
So that the Community can help you better, we will need to know exactly what model printer you're using (it's usually on the top or front of the unit), any error messages you're seeing, and how you connect to your device (USB or networked via WiFi or Ethernet).
Any other details you'd like to give will only help the Community better understand your issue!
