unnecessary space from top

[amanItdose]

While we are working with the below code, we are getting unnecessary space on barcode slip and last line is not printing completely here on slip..

                            "! 0 300 300 210 1" + "\r\n"//set the height of the bitmap and the quantity to print
                                    + "TONE 50" + "\r\n"//print intensity tone 0-200
                                    + "CENTER"                                         + "\r\n"//print speed (less = more accurate) 1 2.5cm/s | 2 - 5cm/s | 3 - 7.6cm/s*/
                                    + "TEXT 7 0 0 50 " + firstLine.toString() + "\r\n"
                                    + "COUNT 1"+ "\r\n"//print speed (less = more accurate) 1 2.5cm/s | 2 - 5cm/s | 3 - 7.6cm/s
                                    + "TEXT 7 0 0 100 " + barcode + "\r\n"
                                    + "B 128 1 1 50 20 66 " + barcode + "\r\n"
                                    + "COUNT -10" + "\r\n"//get the image we stored before in the printer
                                    + "TEXT 7 0 0 140 " + secondLine.toString() + "\r\n"
                                    + "COUNT 1"+ "\r\n"//get the image we stored before in the printer
                                    + "TEXT 7 0 0 160 " + thirdLine.toString() + "\r\n"
                                    + "COUNT 1"+ "\r\n"//get the image we stored before in the printer
                                    + "TEXT 7 0 0 180 " + fourthLine.toString() + "\r\n"//get the image we stored before in the printer

                                    + "FORM" + "\r\n"
                                    + "PRINT" + "\r\n";//print
