I have a requirement to print PDF through a background job in the application. I am planning to set up a Job scheduler and invoke a activity. However this code only seems to connect to a printer but unable to print. any ideas?  

java.net.Socket socket = null; java.net.InetAddress addr = null; java.net.InetSocketAddress socketAddress = null; java.io.BufferedReader reader= null; java.io.BufferedWriter writer= null; java.io.InputStream input = null; java.io.OutputStream output= null;

int port =9100; int timeout=5000; byte[] bodyBytes = null; //byte[] modifiedBodyBytes = null; //String bodyString = null;

try{

    addr = java.net.InetAddress.getByName(hostName);     socket = new java.net.Socket(addr, port);     socket.setSoTimeout(timeout);        bodyBytes = new com.pega.pegarules.pub.util.Base64Util().decodeToByteArray(pyStream);     oLog.infoForced("TestPrinter bodyBytes length "+bodyBytes.length);    // BodyString = new String(bodyBytes, "US-ASCII");    // modifiedBodyBytes= BodyString.getBytes("US-ASCII");

    output = socket.getOutputStream();       oLog.infoForced("TestPrinter output stream "+output);           input = socket.getInputStream();     oLog.infoForced("TestPrinter input stream "+input);            // kick it out     output.write(bodyBytes);     output.flush();     oLog.infoForced("TestPrinter output stream "+output);        socket.shutdownOutput();        reader = new java.io.BufferedReader(new java.io.InputStreamReader(input));      oLog.infoForced("TestPrinter read input stream "+reader);     printerResponse = reader.readLine();     oLog.infoForced("TestPrinter printer response "+printerResponse);          status = "success";     }   catch (Exception e) {   e.printStackTrace();     //oLog.error("TestPrinter Error in sending to printer ");   oLog.error("TestPrinter"+e);

  status = "fail"; } finally {     if (input != null) try { input.close();oLog.infoForced("TestPrinter closed input stream ");} catch (Exception e) {oLog.infoForced("TestPrinter Issue closing input stream ");   }   if (socket != null) try { socket.close(); oLog.infoForced("TestPrinter closed socket connection ");} catch (Exception e) {oLog.infoForced("TestPrinter Issue closing socket ");   }     if (output != null) try { output.close(); oLog.infoForced("TestPrinter closed output stream ");} catch (Exception e) {oLog.infoForced("TestPrinter Issue closing output stream ");} }
