I want some API to control loaded document printing with specified orientation and size without any kind of hacky with CSS

I have developed HTML-based report generation library. Some documents always need to be printed in landscape mode, others have portrait style. For Internet Explorer, we apply third party tool that can internally change print template to landscape before print and/or preview document by inserting some ActiveX component into the HTML layout. It would be great if such functionality have been embedded in the browser already, maybe through some API.

It seems like the simplest solution here is for all browsers to implement CSS3’s @page size. Unfortunately, it looks like only Chromium projects support it right now (possibly because the module is still a draft).
