Landscape printing from HTML

Question

I have a HTML report, which needs to be printed landscape because of the many columns. It there a way to do this, without the user having to change the document settings?

Answer 1

If you want to see landscape on the screen before you print, as well as printing, then in your css, you can set the width to 900px, and the height to 612px.

OP didn't mention A4 size. I assume it's Letter size in my numbers above.
