Wish you are having a great day and welcome to the community;
Your HP Color Laserjet 4550 is a commercial product. I will suggest posting in the forum for HP Business Support and also please expand the description and name OS, this will increase probabilities and provide for a better chance at finding a prompt solution.
You may find the commercial Laserjet board here.
