Raw ESCP Printing through Socket JAVA - socket.io

Question

I have this Raw ESC/POS command for LX-300+, and i want to print it through Print Server using Socket.
String escp = " '\x1B' + '\x40', // initialize the printer, reset printer to defaults " +
" '\x1B' + '\x78' + '\x31', // Set Print Quality NLQ " +
" '\x1B' + '\x6B' + '\x31', // Select typeface San serif " +
" '\x1B' + '\x43' + '\x00' + '\x06', // set Page Length to 6 Inch " +
" '\x1B' + '\x4D', // Select 12 cpi Spacing " +
" '\x1B' + '\x45', // SET Bold Font ";
Question is, can we parse that String of escp with Socket? i use this code,
Socket socket = null;
OutputStream output = null;
BufferedReader reader = null;
try {
socket = new Socket("10.0.5.30", 9100);
socket.setSoTimeout(5000);
output = socket.getOutputStream();
reader = new BufferedReader(new java.io.InputStreamReader(socket.getInputStream()));
} catch (UnknownHostException e) {
// TODO: handle exception
}
if (socket != null && output != null) {
try
{
output.write(escp.getBytes());
output.flush();
socket.shutdownOutput();
output.close();
socket.close();
}
catch (Exception e)
{
System.out.println(e.toString());
}
}
The result is, printer LX-300 is not converting the ESC/POS Command. Just print the String inside escp variable. Any solution to this? i'm using linux 18.04 FYI.
