My code is
-------------------------------------------------
package src;

import com.dao.dto.LrMasterDTO;
import java.awt.*;
import java.awt.font.*;
import java.awt.geom.*;
import java.awt.print.*;
import java.io.BufferedReader;
import java.io.FileReader;
import java.text.*;

/**
* Using JAVA to print simple text file to a printer
*/

public class LRPrint implements Printable {

static AttributedString myStyledText = null;


public static void main(String args[]) {
/**Location of a file to print**/
WriteText wt=new WriteText();
InvoiceText it=new InvoiceText();
// it.main();
wt.main();
String fileName = "D:/dddd.txt";

/**Read the text content from this location **/
String mText = readContentFromFileToPrint(fileName);

/**Create an AttributedString object from the text read*/
myStyledText = new AttributedString(mText);

printToPrinter();

}

/**
* This method reads the content of a text file.
* The location of the file is provided in the parameter
*/
private static String readContentFromFileToPrint(String fileName) {
String dataToPrint = "";

try {
BufferedReader input = new BufferedReader(new FileReader(fileName));
String line = "";
/**Read the file and populate the data**/
while ((line = input.readLine()) != null) {
dataToPrint += line + "\n";
}
} catch (Exception e) {
return dataToPrint;
}
return dataToPrint;
}

/**
* Printing the data to a printer.
* Initialization done in this method.
*/
public static void printToPrinter() {
/**
* Get a Printer Job
*/
PrinterJob printerJob = PrinterJob.getPrinterJob();

/**
* Create a book. A book contains a pair of page painters
* called printables. Also you have different pageformats.
*/
Book book = new Book();
/**
* Append the Printable Object (this one itself, as it
* implements a printable interface) and the page format.
*/
book.append(new LRPrint(), new PageFormat());
printerJob.setPageable(book);

/**
* Calling the printDialog will pop up the Printing Dialog.
* If you want to print without user confirmation, you can directly call printerJob.print()
*
* doPrint will be false, if the user cancels the print operation.
*/
boolean doPrint = printerJob.printDialog();

if (doPrint) {
try {
printerJob.print();
} catch (PrinterException ex) {
System.err.println("Error occurred while trying to Print: "
+ ex);
}
}
}

/**
* This method comes from the Printable interface.
* The method implementation in this class
* prints a page of text.
*/
public int print(Graphics g, PageFormat format, int pageIndex) {

Graphics2D graphics2d = (Graphics2D) g;
/**
* Move the origin from the corner of the Paper to the corner of the imageable
* area.
*/
graphics2d.translate(format.getImageableX(), format.getImageableY());

/** Setting the text color**/
graphics2d.setPaint(Color.black);
/**
* Use a LineBreakMeasurer instance to break our text into lines that fit the
* imageable area of the page.
*/
Point2D.Float pen = new Point2D.Float();
AttributedCharacterIterator charIterator = myStyledText.getIterator();
LineBreakMeasurer measurer = new LineBreakMeasurer(charIterator,
graphics2d.getFontRenderContext());
float wrappingWidth = (float) format.getImageableWidth();
while (measurer.getPosition() < charIterator.getEndIndex()) {
TextLayout layout = measurer.nextLayout(wrappingWidth);
pen.y += layout.getAscent();
float dx = layout.isLeftToRight() ? 0 : (wrappingWidth - layout
.getAdvance());
layout.draw(graphics2d, pen.x + dx, pen.y);
pen.y += layout.getDescent() + layout.getLeading();
}
return Printable.PAGE_EXISTS;
}

}

You've already been told once to EaseUp. Folk on here tend to ignore people who think all their problems are urgent.
I suggest you edit the title of your post if you want to get help.
