You can set a footer using generated content to write into a page margin box at the bottom of the page box. The content you set in a page margin box will appear on every page, unless specified otherwise via CSS.

The content property can contain text, textual content or page numbers. For example, this code will write the content "RealObjects GmbH" in the bottom center margin box of every page:

@page {
    @bottom-center{
        font-family: Times New Roman, serif;
        font-size: 0.5cm; text-align: center;
        content: "RealObjects GmbH";
    }
}
