servlet/jsp中的打印对话框

servlet/jsp中的打印对话框,jsp,servlets,printdialog,Jsp,Servlets,Printdialog,我想在servlet/jsp中显示打印对话框。下面是我的代码: DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE; PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet () ; PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras); PrintService

我想在servlet/jsp中显示打印对话框。下面是我的代码:

DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet () ;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService service = javax.print.ServiceUI.printDialog(null, 200, 200, printService, defaultService, flavor, pras);

if (service != null)
{
  DocPrintJob job = service.createPrintJob();
  Doc doc = new SimpleDoc(decodedImageData, flavor, null);
  job.print(doc, null);
}

它在独立应用程序中运行良好。但是,我无法在servlet/jsp中显示打印对话框。

您需要知道,在这里执行代码的不是客户机。是服务器


您必须创建一个javascript函数才能工作。

我将调用
window.print()在javascript中。在下面试试

<html>
<body>

<a href="javascript:print()">Print</a>
</body>

</html>
