JQuery / Javascript或其他方式静默只打印一次 [英] JQuery/Javascript or other way Silent Print once only

问题描述

任何人都知道如何在不显示跨浏览器，API或类库（如jQuery或JavaScript或其他）的情况下显示打印预览的情况下打印文件。
$ b 打印内容时无需打印预览（只是无声打印）

打印一次，当打印软拷贝时，软拷贝过期，因为我想避免为了安全而多次重印软拷贝理由，特别是如果那是收据是为了报销。

那很简单吗？

为什么我们不会显示打印预览，因为用户可能有
的可能性

• 截图文件然后photoshop文件值


• 更改内容


• 可以复制副本

通过这种方式，很难监控谁在线打印敏感文件。

解决方案

从网页打印e始终与用户交互。但是，您可以防止显示文档。这里显示的是我公司XtremeDocumentStudio .NET产品的HTML5控件。

Anyone knows how to print a file without showing print preview in cross browsers, API or libraries like jQuery or javascript or else.

• Print a content without print preview (just silent print)
• Print once, when softcopy is printed then the softcopy is expired because I want to avoid reprint the softcopy more than one by the user for security reason, especially if that is receipt is for reimburstment.

that is simple or not?

Reason why we won't show the print preview because there is possibility that user could

• screenshot the file then photoshop the file values
• change the contents
• can duplicate copy

In that way it is difficult to monitor who printed the sensitive file in online.

解决方案

Printing from a web page is always with user interaction. However, you can prevent the document from being displayed. Shown here is the HTML5 control from my company's XtremeDocumentStudio .NET product. http://www.gnostice.com/nl_article.asp?id=291&t=Print_without_preview_using_XtremeDocumentStudio_NETs_HTML5_document_viewer_control
