## Displaying a Page Setup Dialog

> You can allow the user to specify page characteristics, such as the paper size and orientation, by displaying a Page Setup dialog. The page information is stored in a `PageFormat` object. Like the Print dialog, the Page Setup dialog is displayed by calling a method on the `PrinterJob` object, `pageDialog`.

> The Page Setup dialog is initialized by using the `PageFormat` passed to the `pageDialog` method. If the user clicks the OK button in the dialog, the `PageFormat` is cloned, altered to reflect the user's selections, and then returned. If the user cancels the dialog, `pageDialog` returns the original, unaltered `PageFormat`.

> `ShapesPrint` could easily be modified to display a Page Setup dialog by adding a call to `pageDialog` after you get the `PrinterJob`.

> >     // Get a PrinterJob
> >     PrinterJob job = PrinterJob.getPrinterJob();
> >     // Ask user for page format (e.g., portrait/landscape)
> >     PageFormat pf = job.pageDialog(job.defaultPage());
