Is there a similar method in Java to Printer.print in VB or do you have to write your own.

And how would you print a text file to a printer.

Hi

Following is the code for printing in java.

PrinterJob printJob = PrinterJob.getPrinterJob(); // Get a printing object
        printJob.setPrintable(theApp.getView()); // The view is the page source
    HashPrintRequestAttributeSet printAttr = new HashPrintRequestAttributeSet();
    if(printJob.printDialog(printAttr)) // Display print dialog
        { // If true is returned...
          try
          {
            printJob.print(printAttr); // then print
          }
          catch(PrinterException pe)
          {
            System.out.println(pe);
            JOptionPane.showMessageDialog(SketchFrame.this,
                                          "Error printing a sketch.",
                                          "Printer Error",
                                          JOptionPane.ERROR_MESSAGE);
          }
        }

Hope this helps

Hi

Following is the code for a sample application which has a simple menu and the content of the window is printed.

import javax.swing.JFrame;
import javax.swing.JEditorPane;
import javax.swing.JMenuBar;
import javax.swing.JMenu;
import java.awt.*;
import java.awt.event.*;
import javax.swing.JMenuItem;
import java.awt.print.*;
import javax.print.attribute.HashPrintRequestAttributeSet ;

public class PrintExample extends JFrame implements ActionListener,Printable
{
    private JEditorPane textarea;
    private JMenuBar mbar;
    private JMenu print;
    private JMenuItem mitem;
    String str = "This is some sample text which will be printed by this program as a test for printing";
    public PrintExample()
    {
        super("Simple Text Editor Example");
        setSize(600,600);
        this.getContentPane().setBackground(Color.white);
        init();
        show();
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }
    private void init()
    {
        mbar = new JMenuBar();
        setJMenuBar(mbar);
        print = new JMenu("Print");
        mitem = new JMenuItem("Print Text");
        mitem.addActionListener(this);
        print.add(mitem);
        mbar.add(print);
        textarea = new JEditorPane();
        textarea.setContentType("text/plain");
        textarea.setText(str);
        getContentPane().add(textarea);
    }

    public void actionPerformed(ActionEvent ae)
    {
        if(ae.getSource() == mitem)
        {
            PrinterJob printJob = PrinterJob.getPrinterJob(); // Get a printing object
            printJob.setPrintable(this); // The view is the page source
            HashPrintRequestAttributeSet printAttr = new HashPrintRequestAttributeSet();
            if(printJob.printDialog(printAttr)) // Display print dialog
            { // If true is returned...
                 try
                  {
                    printJob.print(printAttr); // then print
                  }
                  catch(PrinterException pe)
                  {
                    System.out.println(pe);
                }
            }
        }

    }

    public int print(Graphics g, PageFormat pf, int index)
    {
        if(index>0)
            return NO_SUCH_PAGE;
        Graphics2D gr2 = (Graphics2D)g;
        gr2.translate(pf.getImageableX(),pf.getImageableY( ));
        paint(gr2);
        return Printable.PAGE_EXISTS;

    }

    public static void main(String[] args)
    {
        PrintExample px = new PrintExample();
    }
}
