Printing 'landscape' as an ASP.NET Web Form button click event

ASP.NET (code behind VB.NET)

Is there a printer-friendly method that will set the Printer Layout Orientation mode to "Landscape" for an ASP.NET Web Form button click event?

Printing depends on the browser. Your code-behind can do nothing about it. Neither can your JavaScript (AFAIK). There are some very dirty hacks, mostly based on sending misterious WM_ messages to windows and the like, but beware: they may stop working without notice with any Windows release! And they're not even guaranteed to work across all versions either...

Someday, all browsers will fully support the new CSS standards (http://www.w3.org/Style/CSS/), and you will be able to control all aspects of printing with a simple stylesheet attached to media:print.
