How to print strings with line breaks in java

OK, finally I found a good solution for my bill printing task and it is working properly for me.

This class provides the print service

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;
    }
}

This class demonstrates the bill printing task,

public class HelloWorldPrinter implements Printable {

    @Override
    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
        if (pageIndex > 0) { /* We have only one page, and 'page' is zero-based */
            return NO_SUCH_PAGE;
        }

        Graphics2D g2d = (Graphics2D) graphics;
        g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());

        //the String to print in multiple lines
        //writing a semicolon (;) at the end of each sentence
        String mText = "SHOP MA;"
                + "Pannampitiya;"
                + "----------------------------;"
                + "09-10-2012 harsha  no: 001 ;"
                + "No  Item  Qty  Price  Amount ;"
                + "----------------------------;"
                + "1 Bread 1 50.00  50.00 ;"
                + "----------------------------;";

        //Prepare the rendering
        //split the String by the semicolon character
        String[] bill = mText.split(";");
        int y = 15;
        Font f = new Font(Font.SANS_SERIF, Font.PLAIN, 8);
        graphics.setFont(f);
        //draw each String in a separate line
        for (int i = 0; i < bill.length; i++) {
            graphics.drawString(bill[i], 5, y);
            y = y + 15;
        }

        /* tell the caller that this page is part of the printed document */
        return PAGE_EXISTS;
    }

    public void pp() throws PrinterException {
        PrinterService ps = new PrinterService();
        //get the printer service by printer name
        PrintService pss = ps.getCheckPrintService("Deskjet-1000-J110-series-2");

        PrinterJob job = PrinterJob.getPrinterJob();
        job.setPrintService(pss);
        job.setPrintable(this);

        try {
            job.print();
        } catch (PrinterException ex) {
            ex.printStackTrace();
        }

    }

    public static void main(String[] args) {
        HelloWorldPrinter hwp = new HelloWorldPrinter();
        try {
            hwp.pp();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Do this way:-

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;

String newline = System.getProperty("line.separator");
System.out.println("First line" + newline);
System.out.println("Second line" + newline);
System.out.println("Third line");
