Code to reproduce:
//-----------------------------------------------
import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import javax.swing.*;

public class PrintingPageSize extends JFrame implements Printable {

    public PrintingPageSize() {

        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        JButton print = new JButton("Print...");
        print.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) { showPrintDialog(); }
        });

        getContentPane().add(print, BorderLayout.CENTER);
        pack();
    }

    @Override
    public int print(Graphics g, PageFormat f, int p) { return 0; } // dummy

    private void showPrintDialog() {
        PrinterJob printJob = PrinterJob.getPrinterJob();
        printJob.setPrintable(this);
        printJob.printDialog();
    }

    public static void main(String args[]) {
        EventQueue.invokeLater(new Runnable() {

Please go to "System Settings" -> "Printing", select any printer, right-click -> "Properties" -> "Printer Options" -> "Page Size" and set some value (e.g., "A4").

Then please run the application, push "Print..." button and go to "Page Setup" tab of the print dialog: size is "Custom" instead of "A4".
