I have edited the question "How can I get the serial no. or mac address of a printer dynamically through java." to "How can I get the id of a pri开发者_如何学Pythonnter dynamically through java."
Please try this one ... I hope you find it helpful!
public class MacAdd {
public static void main(String[] args) {
try {
InetAddress add = InetAddress.getByName("192.168.46.53");
NetworkInterface ni1 = NetworkInterface.getByInetAddress(add);
if (ni != null) {
byte[] mac1 = ni1.getHardwareAddress();
if (mac1 != null) {
for (int k = 0; k < mac.length; k++) {
System.out.format("%02X%s", mac[k], (i < mac.length - 1) ? "-" : "");
}
} else {
System.out.println("Address doesn't exist ");
}
} else {
System.out.println("address is not found.");
}
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e) {
e.printStackTrace();
}
}
}
