从ASP.Net打印PDF而不preVIEW [英] Print PDF from ASP.Net without preview

问题描述

我使用iTextSharp的生成PDF文件，我可以在ASP.Net preVIEW这非常好，但我需要直接发送到打印机，没有一个preVIEW。我希望用户点击打印按钮，并自动打印文档。

I've generated a pdf using iTextSharp and I can preview it very well in ASP.Net but I need to send it directly to printer without a preview. I want the user to click the print button and automatically the document prints.

我知道，一个页面可以直接发送到使用JavaScript window.print（打印机），但我不知道如何使它为PDF。

I know that a page can be sent directly to printer using the javascript window.print() but I don't know how to make it for a PDF.

编辑：它不是嵌入式的，我产生像这样;

it is not embedded, I generate it like this;

                ...
                FileStream stream = new FileStream(Request.PhysicalApplicationPath + "~1.pdf", FileMode.Create);
                Document pdf = new Document(PageSize.LETTER);
                PdfWriter writer = PdfWriter.GetInstance(pdf, stream);
                pdf.Open();
                pdf.Add(new Paragraph(member.ToString()));
                pdf.Close();

                Response.Redirect("~1.pdf");
                ...

和我在这里。

推荐答案

最后我做到了，但我不得不使用一个IFRAME，我在ASPX中定义一个IFrame并没有设置src属性，在CS文件我国产生成的PDF文件和设置的iFrame的src属性作为生成的PDF文件名，这样的;

Finally I made it, but I had to use an IFRAME, I defined an IFrame in the aspx and didn't set the src property, in the cs file I made generated the pdf file and set the src property of the iFrame as the generated pdf file name, like this;

Document pdf = new Document(PageSize.LETTER);
PdfWriter writer = PdfWriter.GetInstance(pdf, 
new FileStream(Request.PhysicalApplicationPath + "~1.pdf", FileMode.Create));
pdf.Open();

//This action leads directly to printer dialogue
PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);
writer.AddJavaScript(jAction);

pdf.Add(new Paragraph("My first PDF on line"));
pdf.Close();

//Open the pdf in the frame
frame1.Attributes["src"] = "~1.pdf";

和，使得的伎俩，但是，我认为我应该实现您的解决方案斯特凡，问题是，我是新来asp.net和JavaScript，如果我没有一个完整的源$ C ​​$ c口不能code你的建议，但至少是第一步，我感到非常惊讶如何HTML和JavaScript多code，我需要学习。日Thnx。

And that made the trick, however, I think that i should implement your solution Stefan, the problem is that I'm new to asp.net and javascript and if I don't have a complete source code I could not code your suggestion but at least is the first step, I was very surprised how much code in html and javascript i need to learn. Thnx.
