Jeg ville høre om du ikke har et eksempel på en udskrift funktion.

Disse 2 klasser er et Java GUI program, som viser hvordan man printer i java:


import java.awt.*;
import java.awt.print.*;

import javax.swing.JComponent;

public class ComponentPrintable
    implements Printable {
  private Component mComponent;
 
  public ComponentPrintable(Component c) {
    mComponent = c;
  }
 
  public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
    if (pageIndex > 0) return NO_SUCH_PAGE;
    Graphics2D g2 = (Graphics2D)g;
    g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
    boolean wasBuffered = disableDoubleBuffering(mComponent);
    mComponent.paint(g2);
    restoreDoubleBuffering(mComponent, wasBuffered);
    return PAGE_EXISTS;
  }

  private boolean disableDoubleBuffering(Component c) {
    if (c instanceof JComponent == false) return false;
    JComponent jc = (JComponent)c;
    boolean wasBuffered = jc.isDoubleBuffered();
    jc.setDoubleBuffered(false);
    return wasBuffered;
  }
 
  private void restoreDoubleBuffering(Component c, boolean wasBuffered) {
    if (c instanceof JComponent)
      ((JComponent)c).setDoubleBuffered(wasBuffered);
  }
}







Og Main klassen:

import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import javax.swing.*;
import javax.swing.event.*;

public class SwingPrinter extends JFrame {
  public static void main(String[] args) {
    new SwingPrinter();
  }
 
  private PageFormat mPageFormat;
 
  public SwingPrinter() {
    super("SwingPrinter");
    createUI();
    PrinterJob pj = PrinterJob.getPrinterJob();
    mPageFormat = pj.defaultPage();
    setVisible(true);
  }

  protected void createUI() {
    setSize(300, 300);

    JMenuBar mb = new JMenuBar();
    JMenu file = new JMenu("File", true);
    file.add(new FilePrintAction()).setAccelerator(
        KeyStroke.getKeyStroke(KeyEvent.VK_P, Event.CTRL_MASK));
    file.add(new FilePageSetupAction()).setAccelerator(
        KeyStroke.getKeyStroke(KeyEvent.VK_P,
            Event.CTRL_MASK | Event.SHIFT_MASK));
    file.addSeparator();
    file.add(new FileQuitAction()).setAccelerator(
        KeyStroke.getKeyStroke(KeyEvent.VK_Q, Event.CTRL_MASK));
    mb.add(file);
    setJMenuBar(mb);
   
    JTextArea t = new JTextArea();
    getContentPane().add(t);

    addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }
    });
  }

  public class FilePrintAction extends AbstractAction {
    public FilePrintAction() {
        super("Print");
    }
   
    public void actionPerformed(ActionEvent ae) {
      PrinterJob pj = PrinterJob.getPrinterJob();
      ComponentPrintable cp = new ComponentPrintable(getContentPane());
      pj.setPrintable(cp, mPageFormat);
      if (pj.printDialog()) {
        try { pj.print(); }
        catch (PrinterException e) {
          System.out.println(e);
        }
      }
    }
  }

  public class FilePageSetupAction extends AbstractAction {
    public FilePageSetupAction() { super("Page setup..."); }
    public void actionPerformed(ActionEvent ae) {
      PrinterJob pj = PrinterJob.getPrinterJob();
      mPageFormat = pj.pageDialog(mPageFormat);
    }
  }
 
  public class FileQuitAction extends AbstractAction {
    public FileQuitAction() { super("Quit"); }
    public void actionPerformed(ActionEvent ae) {
      System.exit(0);
    }
  }
}

Her har du et par links som indeholder eksempler på hvordan du sender data til din printer.
