How to print in Java?

[thelordoftherings]

Hello,

I would like to create a button that by clicking on it will open the print component of the PC, just like when I click File->Print... in a browser or in any other window.
What is the code I need to put at the button click event in order to do that?

Hey sedj,

Thank you for the link, I do have few questions though.
These examples show how to print something from an input stream, I simply want to open the default printer object and the user will click the "print" once it is opened. I tried to play with this code a bit but haven't managed to acheive this. Could you please show me a code example?

Thank you in advance,
Roy

1) What exactly do you want to print ?

2) If you just want to print to the default service, what is the point of opening the OS gui bit ? You may aswell just print straight out.

I just want to open the print service, like the window that opens when I choose File-> Print... at Internet explorer for example...

Well if you want the OS print dialog :

PrinterJob pjob = PrinterJob.getPrinterJob();
pjob.printDialog();

But thats not actually going to do a lot on its own - you have to have a class that implements Printable, and is aware of what it actually needs to print ...

eg :

	class PrintableClass implements Printable {
		public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) {
			return 0;
		}
	}

	public void doit() {
		PrinterJob pjob = PrinterJob.getPrinterJob();
		pjob.printDialog();
		PageFormat pf = pjob.defaultPage();
		pjob.setPrintable(new PrintableClass(), pf);
		try {
			if (pjob.printDialog()) {
				pjob.print();
			}
		} catch (PrinterException e) {
			e.printStackTrace(System.out);
		}
	}
