title: Apache POI: change page format for Excel worksheet
body: <p>Is there a way to change the page size and layout while creating the Excel document using Apache POI? The default one is A4-vertical, while I need A6-horizontal (landscape).</p>
  
  <p>I don't think that this question requires code sample, the Excel document is created just as described in the manual:</p>
  
  <pre><code>Workbook wb = new HSSFWorkbook();
  Sheet sheet = wb.createSheet("new sheet");
  </code></pre>
