Is it possible to print applet using the printer. If yes, how?
I have a button on my applet. When the user clicks on that button, the applet should be printed. My applet is not signed.
Thanks

public void printPage() {
try{
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.pageDialog(printJob.defaultPage());
printJob.setPrintable(this, printJob.defaultPage());
if(printJob.printDialog()){
printJob.print();
}
return;
}
catch(PrinterException pe) {
EuamAppletLogger.error(pe, "Exception Caught");
}
}

/**
* Prints the page at the specified index into the specified Graphics context in the specified format.

* @param g
* @param pg
* @param page

* @return int
*/
public int print(Graphics g, PageFormat pg, int page) throws PrinterException {
Graphics2D g2 = (Graphics2D) g;
if (page >= 1)
return Printable.NO_SUCH_PAGE;
g2.translate(pg.getImageableX(), pg.getImageableY());
paint (g2);
System.gc();
return PAGE_EXISTS;
}
this code pops-up 'An applet would like to print. Do you want to continue?' but the browser just hungs there. I am not able to click on yes/no option. Any thought?
Thanks

So Tim, I can not print java applets on an browser? There must be some way we can print the applet.
Any utility which converts applet to html? basically, I have jtree in applet which is to be printed. Any suggestions on how to print the jtree?

There's no simple correspondence between an applet's contents and HTML so it can't be converted. An applet can be made to print, however - it's just that the applet has to be signed. This is a security precaution so that rogue applets that print obscene pictures on 3700 pages can't be let loose indiscriminantly on the Internet.
A common alternative is to send the data that you want back to the server that the applet loaded from and have a servlet or JSP construct a printable page either in HTML or PDF form. That page can then be printed via the browser File/Print menu command. This isn't quite as convenient as printing straight from the applet, but sometimes you can format better and there's no need to sign the applet.
