Printing in landscape

[Pepito]

First of all, sorry about my English. I'm Spanish. Well, i have to print
one html document change its orientation to landscape and i wish to do
this, without going to the print configure menu a change the paper
orientation. Does anybody knows how to do this with Javascript or CSS
sheet style??? I spend many time, but i don't find any solution yet. I
found something about "@page rule", but it doesn't work or i don't know
how it works.


Thanks in advance...
