                    .appendByte((byte) 0x1b).appendString("K1").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("C").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("K2").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("C").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("K3").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("C").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("K4").appendByte((byte) 0x0d)
                    .appendByte((byte) 0x1b).appendString("C").appendByte((byte) 0x0d);
                    socket.write(buf);

I don't think Buffer here is the standard Java buffer class - i.e. java.nio.Buffer

I suspect this is an internal class - in which case you'd need to look inside that class to see how it is representing the data and how to print it out.

If it contains a ByteBuffer then that has a getChar() method which you can use to read and print the current contents of the buffer.

thanks for your comments.

Yes I am using a 3rd party buffer class and the link to it is http://vertx.io/docs/apidocs/io/vertx/core/buffer/Buffer.html
