我知道我们已经有了这个问题，但他们根本无法帮助我。如何在图片上创建和打印一个漂亮的收据/票据：
这是我打印的VOID：
public void ReceiptPrinter(Node node){
Printer printer = Printer.getDefaultPrinter();
PageLayout page = printer.getDefaultPageLayout();
double X = page.getPrintableWidth() / (node.getBoundsInParent().getWidth());
double Y = page.getPrintableHeight() / (node.getBoundsInParent().getHeight());
System.out.println("X = "+X);
System.out.println("Y = "+Y);
Scale SCL = new Scale(X, Y);
node.getTransforms().add(SCL);
PrinterJob PJ = PrinterJob.createPrinterJob(printer);
if(PJ != null){
boolean Success = PJ.printPage(page, node);
if(Success){
PJ.endJob();
}
}
node.getTransforms().remove(SCL);
}
这样调用并执行：
new ReceiptPrinter().ReceiptPrinter(My_TableView);

您可以使用JasperReports创建收据/帐单。
由于JasperReports无法与普通JavaFX完美配合，因此您应该使用＆＃39;连接器＆＃39;或观众。
您可以使用：
