Using Print Setup Dialogs (The Java™ Tutorials > 2D Graphics > Printing) Traditionally, the user wants to see the page setup and print dialog boxes. From the print dialog you can select a printer, specify pages to print, and set the number of copies. An application displays a print dialog when the user presses a button related to the print command, or chooses an item from the print menu. To display this dialog, call the printDialog method of the PrinterJob class: PrinterJob pj = PrinterJob.getPrinterJob(); ... if (pj.printDialog()) { try {pj.print();} catch (PrinterException exc) { System.out.println(exc); } } ... This method returns true if the user clicked OK to leave the dialog, and false otherwise. The printDialog method in the above code snippet opens a native print dialog. You can change the page setup information contained in the PageFormat object by using the page setup dialog. To display the page setup dialog, call the pageDialog method of the PrinterJob class. PrinterJob pj = PrinterJob.getPrinterJob(); PageFormat pf = pj.pageDialog(pj.defaultPage());
