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

I tried Denis's answer and hit some problems (portrait pages didn't print properly after going after landscape pages), so here is my solution:

body {
  margin: 0;
  background: #CCCCCC;
}

div.page {
  margin: 10px auto;
  border: solid 1px black;
  display: block;
  page-break-after: always;
  width: 209mm;
  height: 296mm;
  overflow: hidden;
  background: white;
}

div.landscape-parent {
  width: 296mm;
  height: 209mm;
}

div.landscape {
  width: 296mm;
  height: 209mm;
}

div.content {
  padding: 10mm;
}

body,
div,
td {
  font-size: 13px;
  font-family: Verdana;
}

@media print {
  body {
    background: none;
  }
  div.page {
    width: 209mm;
    height: 296mm;
  }
  div.landscape {
    transform: rotate(270deg) translate(-296mm, 0);
    transform-origin: 0 0;
  }
  div.portrait,
  div.landscape,
  div.page {
    margin: 0;
    padding: 0;
    border: none;
    background: none;
  }
}

  

    First page in Portrait mode
  


  

    

      Second page in Landscape mode (correctly shows horizontally in browser and prints rotated in printer)
    
  


  

    Third page in Portrait mode
