This code hangs forever on the last line.

The result should probably be an exception since one is trying to print after the last page.

PrinterJob pj = PrinterJob.createPrinterJob();
pj.getJobSettings().setPageRanges(new PageRange(1, 1));
pj.printPage(new Label("Page 1"));
pj.printPage(new Label("Page 2 - one too much"));

Labelling as critical since a small programming error might hang the whole app without any way of knowing the reason.
