I think the bug is in the jdk, and I'll write something small later to
prove this.
And here it is, I asked ChatGPT ("Create a program in java that uses the
Pageable interface to print a 10 pages document with the numbers from 1
to 10. The print option dialog should be used for additional manual
configuration.") and modified it slightly:
public class PageableTest extends Book
{
private final int numPages = 2;
public static void main(String[] args)
{
PrinterJob job = PrinterJob.getPrinterJob();
job.setPageable(new PageableTest());
// Show print dialog for manual configuration
if (job.printDialog())
{
try
{
job.print();
}
catch (PrinterException e)
{
e.printStackTrace();
}
}
}
// Return the number of pages
@Override
public int getNumberOfPages()
{
return numPages;
}
// Not needed for this example
@Override
public PageFormat getPageFormat(int pageIndex) throws
IndexOutOfBoundsException
{
if (pageIndex >= numPages)
{
throw new IndexOutOfBoundsException("Invalid page index");
}
return PrinterJob.getPrinterJob().defaultPage();
}
// Return the Printable that will render the content
@Override
public Printable getPrintable(int pageIndex) throws
IndexOutOfBoundsException
{
if (pageIndex >= numPages)
{
throw new IndexOutOfBoundsException("Invalid page index");
}
return new Printable()
{
@Override
public int print(Graphics g, PageFormat pf, int index)
throws PrinterException
{
Graphics2D g2d = (Graphics2D) g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
g2d.setFont(new Font("Serif", Font.BOLD, 72));
g2d.drawString(String.valueOf(index + 1), 100, 100);
return Printable.PAGE_EXISTS;
}
};
}
}
