How to print string with newline character in Java

I need to use java to print a string, so I like the following solutions, which have been searched a lot by Google I made some changes to print the string without displaying the print dialog box My problem is that although this method prints the string correctly, it does not break the line as I defined Please tell me how to print a string with a newline character

public class PrintBill implements Printable {

    private static final String mText = "SHOP MA\n"
            + "----------------------------\n"
            + "Pannampitiya\n"
            + "09-10-2012 harsha  no: 001\n"
            + "No  Item  Qty  Price  Amount\n"
            + "1 Bread 1 50.00  50.00\n"
            + "____________________________\n";

    private static final AttributedString mStyledText = new AttributedString(mText);

    static public void main(String args[]) throws PrinterException {
        PrinterService ps = new PrinterService();
        PrintService pss = ps.getCheckPrintService("Samsung-ML-2850D-2");//get the printer service by printer name


        PrinterJob printerJob = PrinterJob.getPrinterJob();
        printerJob.setPrintService(pss);

        Book book = new Book();
        book.append(new PrintBill(),new PageFormat());       

        printerJob.setPageable(book);


        try {
            printerJob.print();
            System.out.println(printerJob.getPrintService().getName());
            System.out.println("Print compleated..");
        } catch (PrinterException exception) {
            System.err.println("Printing error: " + exception);
            exception.printStackTrace();
        }

    @Override
    public int print(Graphics g,PageFormat format,int pageIndex) {
        Graphics2D g2d = (Graphics2D) g;

        g2d.translate(format.getImageableX(),format.getImageableY());

        g2d.setPaint(Color.black);        

        Point2D.Float pen = new Point2D.Float();
        AttributedCharacterIterator charIterator = mStyledText.getIterator();
        LineBreakMeasurer measurer = new LineBreakMeasurer(charIterator,g2d.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(g2d,pen.x + dx,pen.y);
            pen.y += layout.getDescent() + layout.getLeading();

        }
        return Printable.PAGE_EXISTS;
    }
}

Printer service delivery course

public class PrinterService {

    public PrintService getCheckPrintService(String printerName) {
        PrintService ps = null;
        DocFlavor doc_flavor = DocFlavor.STRING.TEXT_PLAIN;
        PrintRequestAttributeSet attr_set =
                new HashPrintRequestAttributeSet();

        attr_set.add(new Copies(1));
        attr_set.add(Sides.ONE_SIDED);
        PrintService[] service = PrintServiceLookup.lookupprintServices(doc_flavor,attr_set);

        for (int i = 0; i < service.length; i++) {
            System.out.println(service[i].getName());
            if (service[i].getName().equals(printerName)) {
                ps = service[i];
            }
        }
        return ps;
    }
}

Solution

Do this: –

String newline = System.getProperty("line.separator");

private static final String mText = "SHOP MA" + newline +
        + "----------------------------" + newline +
        + "Pannampitiya" + newline +
        + "09-10-2012 harsha  no: 001" + newline +
        + "No  Item  Qty  Price  Amount" + newline +
        + "1 Bread 1 50.00  50.00" + newline +
        + "____________________________" + newline;
