打印窗格或整个FXML页面JAVAFX

如何打印窗格或整个FXML页面。 我尝试这两种方法（doPrint和doPrintSecond在控制器中）打印，但不起作用； 请纠正我哪里错了。 是否有其他方法打印fxml页面或窗格

FXML代码

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.text.*?>
<?import com.jfoenix.controls.*?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane id="AnchorPane" prefHeight="186.0" prefWidth="457.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="javafxapplication10.PrintPaneController">
   <children>
      <Pane fx:id="printPane" prefHeight="139.0" prefWidth="457.0" style="-fx-background-color: grey;">
         <children>
            <Label layoutX="179.0" layoutY="21.0" text="Print">
               <font>
                  <Font size="45.0" />
               </font>
            </Label>
            <Label layoutX="152.0" layoutY="93.0" text="JavaFX print Pane">
               <font>
                  <Font size="18.0" />
               </font>
            </Label>
         </children>
      </Pane>
      <Pane layoutY="139.0" prefHeight="56.0" prefWidth="457.0" style="-fx-background-color: white;">
         <children>
            <JFXButton buttonType="RAISED" layoutX="192.0" layoutY="14.0" onAction="#printActionPane" text="Print">
               <font>
                  <Font size="20.0" />
               </font>
            </JFXButton>
         </children>
      </Pane>
   </children>
</AnchorPane>

您可以使用此代码打印窗格。此外，借助页面布局，您可以设置所需的纸张大小、方向，还可以设置页面的边距

我希望这有帮助

    Printer printer = Printer.getDefaultPrinter();
    PageLayout pageLayout = printer.createPageLayout(Paper.A4, 
    PageOrientation.PORTRAIT, Printer.MarginType.HARDWARE_MINIMUM);
    PrinterJob job = PrinterJob.createPrinterJob();
    if (job != null && job.showPrintDialog(printPane.getScene().getWindow())) {
      boolean success = job.printPage(pageLayout, printPane);
      if (success) {
        job.endJob();
      }
    }

    Printer printer = Printer.getDefaultPrinter();
    PageLayout pageLayout = printer.createPageLayout(Paper.A4, 
    PageOrientation.PORTRAIT, Printer.MarginType.HARDWARE_MINIMUM);
    PrinterJob job = PrinterJob.createPrinterJob();
    if (job != null && job.showPrintDialog(printPane.getScene().getWindow())) {
      boolean success = job.printPage(pageLayout, printPane);
      if (success) {
        job.endJob();
      }
    }
