Print from tab to a printer connected through LAN to same network

Question

I have a printer connected through LAN to the same network that of an android tab. The printing should be a specific format with images and tables. I don't want any dialogs shown during the printing process. The printing process should be automatic.

try {


                Socket sock = new Socket("192.168.10.22", 9100);
                PrintWriter oStream = new PrintWriter(sock.getOutputStream());
                oStream.println("HI,test from Android Device");
                oStream.println("\n\n\n");
                oStream.println("Printing works!!!");
                oStream.println("\n\n\n");
                oStream.close();
            } catch (Exception e) {

                e.printStackTrace();


            }

I tried the above code but I can't change the font size or print images
