问题
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.

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
