If the printer uses a dynamic IP address and has been without power, the DHCP lease may have expired, and the printer may have been assigned a new IP address. Devices attempting to connect using the old IP address will fail. * Why Not A (The printer has a static IP address): A static IP address would remain unchanged, so this would not cause the issue. * Why Not C (The printer has an APIPA): APIPA (Automatic Private IP Addressing) would occur only if the printer cannot contact the DHCP server, but this isn't described in the scenario. * Why Not D (The printer has a public IP address): A public IP address is irrelevant in a local network scenario.
