The @page rule has been cut down in scope from CSS2 to CSS2.1. The full CSS2 @page rule was reportedly implemented only in Opera (and buggily even then). My own testing shows that IE and Firefox don't support @page at all. According to the now-obsolescent CSS2 spec section 13.2.2 it is possible to override the user's setting of orientation and (for example) force printing in Landscape but the relevant "size" property has been dropped from CSS2.1, consistent with the fact that no current browser supports it. It has been reinstated in the CSS3 Paged Media module but note that this is only a Working Draft (as at July 2009). Conclusion: forget about @page for the present. If you feel your document needs to be printed in Landscape orientation, ask yourself if you can instead make your design more fluid. If you really can't (perhaps because the document contains data tables with many columns, for example), you will need to advise the user to set the orientation to Landscape and perhaps outline how to do it in the most common browsers. Of course, some browsers have a print fit-to-width (shrink-to-fit) feature (e.g. Opera, Firefox, IE7) but it's inadvisable to rely on users having this facility or having it switched on.

你也可以使用非标准的IE-only css属性写入模式

div.page    { 
   writing-mode: tb-rl;
}

你可以尝试以下方法:

@page {
    size: auto
}

你可以使用css2 @page规则，它允许你将“size”属性设置为横向。

如前所述，size属性是您所需要的。要在打印时设置页面的方向和大小，您可以使用以下命令:

/* ISO Paper Size */
@page {
  size: A4 landscape;
}

/* Size in mm */    
@page {
  size: 100mm 200mm landscape;
}

/* Size in inches */    
@page {
  size: 4in 6in landscape;
}

下面是@page文档的链接。

我用横向设置创建了一个空白的MS文档，然后在记事本中打开它。复制并粘贴以下内容到我的html页面

<style type="text/css" media="print">
   @page Section1
    {size:11 8.5in;
    margin:.5in 13.6pt 0in 13.6pt;
    mso-header-margin:.5in;
    mso-footer-margin:.5in;
    mso-paper-source:4;}
div.Section1
    {page:Section1;}
</style>



<div class="Section1"> put  text / images / other stuff  </div>

打印预览以横向大小显示页面。这似乎在IE和Chrome上工作得很好，没有在FF上测试。
