How to fire paper cutter of ESC/POS from android application

Question

I am developing an Point-Of-Sale android application. My Tysso PRP 188 printer is connected by Ethernet. I can print on the printer but i don't know how to cut paper after print is finished.

The String i am using to print is below:

                msg = "\n" + 
                            "                   KOT \n"+
                            "Voucher No: " + vno + "  \t  Order No: " + ono + "\n" + 
                            "Waiter Name: " + wname + " \t  Table: " + tno + "\n" + 
                            "Time: " + time + " \n" +
                            "- - - - - - - - - - - - - - - - - - - - - - - -\n" +
                            "       Item                          Quantity  \n" +
                            "- - - - - - - - - - - - - - - - - - - - - - - -\n" + 
                            "\n" + 
                            itemslist +
                            "\n- - - - - - - - - - - - - - - - - - - - - - - -\n" + 
                            "\n\n\n\n\n\n\n\n";

and this is how i print it.

private class MyPrinter extends AsyncTask<String, String, String>
{

    Socket sock;
    PrintWriter oStream;
    DataInputStream is;
    ProgressDialog pDialog = null;
    Context context;

    public MyPrinter(Context context)
    {
        this.context = context;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(CustomerInformation.this);
        pDialog.setTitle("Print Order");
        pDialog.setMessage("Please Wait ...");
        pDialog.show();
    }

    protected String doInBackground(String... params) {

        try 
        {
            sock = new Socket(params[0], Integer.parseInt(params[1]));
            sock.setSoTimeout(300);

            is = new DataInputStream(sock.getInputStream());

            if(sock.getRemoteSocketAddress() != null)
            {
            oStream = new PrintWriter(sock.getOutputStream());

            oStream.println(params[2]);

            }
            else
            {
                Log.i("cycle", "Remote Socket Address");
            }



            oStream.flush();
            oStream.close();

            sock.close();

        }
        catch (UnknownHostException e) 
        {
            Log.i("cycle", "00");
            e.printStackTrace();
        } 
        catch (IOException e) 
        { 

            Log.i("cycle", "11");
            e.printStackTrace();
        }
        finally{

        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);

        if(pDialog != null)
            if(pDialog.isShowing())
                pDialog.dismiss();


        finish();

    }

}

I am not sure but i think to solve my problem i have to convert my Text-to-print in some kind of encoding which this printer understands so how to do it i don't know !!!

How you print that order detail? Can you please share your code? — Waqar Vicky, Sep 18 '18 at 10:32

Thanks to all. I achived this by:

oStream.println(new char[]{0x1D, 0x56, 0x41, 0x10});

In Typescript : this.cut = new Uint8Array(4); this.cut[0] = 0x1D; this.cut[1] = 0x56; this.cut[2] = 0x41; this.cut[3] = 0x10; – Gilsdav May 11 '18 at 16:52
Works great for me! – Sam Chen Nov 12 '19 at 17:49

To cut paper use this commands after printing text:

oStream.write(0x1D);
oStream.write(86);
oStream.write(48);              
oStream.write(0);

before this some new lines may be needed. I added oStream.println("\n\n\n"); to put new lines and cut – Alp Altunel Jun 11 '17 at 21:16

actually I sent this

 oStream.println(new char[]{0x1D, 0x56, 66, 0x00});

and it cut the paper. No need to add empty lines to the text. This automatically adds line feed and cuts.

Try adding the escape code for the auto cutter to the end of the print string. You may have to do a char(0x1B) . to get the right form of the output. This link might help you with the conversion between integer and character: can we convert integer into character

for new lines

osStream.println("\n\n");

osStream.println(new char[]{29,86,66});

or

printWriter.println(new char[]{0x1D, 0x56, 0x42});

is all done.
