To confirm whether a network printer has connectivity issues, the technician should use: * ping: This command checks the connectivity to the printer by sending packets and measuring the response time. It helps determine if the printer is reachable on the network. * netstat: Provides statistics and current network connections but does not directly confirm connectivity to a specific device. * net: Used for network resources management but not specifically for checking connectivity. * nslookup: Used for querying DNS to obtain domain name or IP address mapping, not for checking connectivity.
