使用iText打开PDF时自动打开打印对话框 [英] Open print dialog automatically when PDF opened, using iText

问题描述

我需要能够在打开pdf时自动提供打印对话框。我需要用javascript来做这件事，我想知道我是否有可能使用iText附加所述javascript？这样做会更加清晰，因为我目前已经在使用iText库了。否则有更好的方法吗？目前使用：

I need to be able provide the print dialog automatically when a pdf is opened. I need to do it with javascript and I was wondering if it is possible for me to append said javascript using iText? It would be much cleaner for me to do so because I am currently already utilizing the iText library. Otherwise is there a better way to do this? Currently using:

Document document = new Document();
document.add(New Paragraph("<script type="text/javascript">print();</script>"));

但是，这不会对pdf进行任何更改，但在打开时仍然无法打印。

This, however, makes no changes to the pdf but still does not print when it is opened.

提前致谢。

推荐答案

我做了类似的事，没有Javascript ，使用iText API调用：

I did something like this without Javascript, using iText API calls:

PdfWriter writer = ...;
PdfAction action = new PdfAction(PdfAction.PRINTDIALOG);
writer.setOpenAction(action);
