How to print an Html Document

P: n/a
I was just wondering how I should go about printing an html document. I can
read it in and print it out as source but I would like to print it as it
should display. At the moment I hace been having it scan the source for tags
and set formatting based on them. The problem with this is it is long, slow
and means I have to manually draw tables and coloured backgrounds. I know I
am probably doing it the long hard way but the only nfo I keep finding
doesn't seem to help me out.

Thanks in advance

Raymond

Hi Raymond,

use to display your HTML a modified JEditorPane, like in the example
below. Create a class, which extends JEditorPane and implement the
printable and serializable interfaces. It's very important, that you
set
the content type of the editor to "text/html", than read your
HTML-document
into the editor. For printing create a new PrinterJob and set your
painter.
In your case the painter is your editor. If you want to display the
standard
printer dialog call the printDialog() method of the PrinterJob.
Call print() to print out yout HTML document.

Regards,
Klaus
// Part of code

printableEditorPane jEditorPane = new printableEditorPane();

jEditorPane.setContentType("text/html");
jEditorPane.read(new BufferedReader(...), ""); /* Read your HTML File
*/

PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(jEditorPane);
if (job.printDialog()) /* Displays the standard system print dialog
*/
{
try
{
job.print();
}
catch (Exception ex)
{
System.out.println(ex);
}
}

// End
public class printableEditorPane extends JEditorPane implements
Printable, Serializable
{
public int print (Graphics g, PageFormat pf, int pageIndex) throws
PrinterException
{
Graphics2D g2 = (Graphics2D)g;
g2.setColor (Color.black);

RepaintManager.currentManager(this).setDoubleBuffe ringEnabled(false);
Dimension d = this.getSize();
double panelWidth = d.width;
double panelHeight = d.height;
double pageWidth = pf.getImageableWidth();
double pageHeight = pf.getImageableHeight();
double scale = pageWidth / panelWidth;
int totalNumPages = (int)Math.ceil(scale * panelHeight /
pageHeight);

// Check for empty pages
if (pageIndex >= totalNumPages) return Printable.NO_SUCH_PAGE;

g2.translate(pf.getImageableX(), pf.getImageableY());
g2.translate(0f, -pageIndex * pageHeight);
g2.scale(scale, scale);
this.paint(g2);

return Printable.PAGE_EXISTS;
}
}
