            double width = pageformat.getImageableWidth();
            g2d.translate((int) pageformat.getImageableX(), (int) pageformat.getImageableY());
            FontMetrics metrics=g2d.getFontMetrics(new Font("Arial",Font.BOLD,7));
            int idLength=metrics.stringWidth("000");
            int amtLength=metrics.stringWidth("000000");
            int qtyLength=metrics.stringWidth("000000");
            int priceLength=metrics.stringWidth("00000");
            int prodLength=(int)width-idLength-amtLength-priceLength-17;

            int productPosition = 0;
            int discountPosition=prodLength+0;
            int pricePosition =discountPosition+idLength + 10;
            int qtyPosition = pricePosition + priceLength + 4;
            int amtPosition = qtyPosition + qtyLength;
            try {
                int y=20;
                int yShift = 10;

                g2d.setFont(new Font("Monospaced",Font.PLAIN,9));
                g2d.drawString("............................", 12, y);y+=yShift;
                g2d.drawString("  Restaurant Bill Reciept   ", 12, y);y+=yShift;
                g2d.drawString("----------------------------", 12, y);y+=headerRectHeighta;


                g2d.drawString("......................................", 10, y);y+=yShift;


                g2d.drawString("......................................", 10, y);;y+=yShift;

                g2d.drawString("          Free Home Delivery          ", 10, y);;y+=yShift;

            }
            catch(Exception r)
            {
                r.printStackTrace();
            }
            result = PAGE_EXISTS;
        }
        return result;
    }


}

Here the error i got is like this The type bill.BillPrintable must implement the inherited abstract method Printable.print(Graphics, PageFormat, int).Dont know how the problem arises and how to solve the problem.please help me to solve thanks in advance This is my imported statements.please have a look

import java.awt.Font;
import java.awt.Graphics2D;
import javafx.print.Paper;
import com.sun.prism.Graphics;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
import java.text.*;
import java.awt.print.*;
import java.awt.print.PageFormat.*;
import java.awt.print.Paper.*;
import javax.swing.UIManager;
import java.awt.FontMetrics;

Answer 1

You import class Graphics from a wrong package:

import com.sun.prism.Graphics

must be

import java.awt.Graphics

Also the following imports are unessasary:

import java.text.*;
import java.awt.print.*;
import java.awt.print.PageFormat.*;
import java.awt.print.Paper.*;

Pay attention: You should not use com.sun classes directly
