To check and change the status from "Samsung Printer Offline" to "Online," begin by ensuring the printer is powered on and connected to the same network as your computer. Access the control panel on the printer or use the printer software on your computer to check the connection status. If it displays as offline, attempt restarting both the printer and the computer. Confirm that the network settings, including Wi-Fi connectivity, are stable. If the issue persists, reconfigure the printer settings through the control panel or the printer software on your computer.
