Hi. I'm David, and I'm happy to help you.
To be able to assist you better, could you share a few more details?
- Where does the error appear? Is it displayed on the printer's physical screen, or inside a Windows/app pop-up on your PC?
- What is the exact manufacturer and model of your printer?
- Is the printer connected using Wi-Fi, or an Ethernet network cable directly to your router?
- Were there any recent network changes? (e.g., a new Wi-Fi router, changed network password, or new internet service provider)
- Can you print a regular document from your PC, or is all printing completely blocked?
Looking forward to your reply.
