## **1. What Does “Printer Offline” Mean?**
When your computer shows your Epson EcoTank ET-3850 as “Offline,” it means the computer cannot communicate with the printer.
This doesn’t always mean the printer is completely broken — it usually means:
✔ The device isn’t reachable over Wi-Fi or USB
✔ The computer’s printer settings are incorrect
✔ A driver or software issue blocks communication
✔ Network configurations have changed
Understanding the difference between a *truly offline hardware state* (no power, hardware failure) and a *software offline error* is key to resolving this.

**professional help by phone at 1-866-203-7571**
### **D. Check Network Band (2.4 GHz vs 5 GHz)**
