title: ESC / POS Thermal Printer - How to set line spacing inside page mode?
body: <p>I have an Sweda (same as SAM4S) thermal printer that supports ESC/POS.</p>
  
  <p>The issue is that I am not able to set line spacing inside the page mode. Here is what I do:</p>
  
  <ul>
  <li><p>Enter page mode</p>
  
  <p>{ESC, 0x4C}</p></li>
  <li><p>Set line spacing</p>
  
  <p>{ESC, 0x33, (byte)48}</p></li>
  <li><p>Set area Size</p>
  
  <pre><code>send((byte)(x &amp; 255), (byte)(x &gt;&gt; 8 &amp; 255),
        (byte)(y &amp; 255), (byte)(y &gt;&gt; 8 &amp; 255),
        (byte)(width &amp; 255), (byte)(width&gt;&gt; 8 &amp; 255),
        (byte)(height &amp; 255), (byte)(height &gt;&gt; 8 &amp; 255));
  </code></pre></li>
  <li><p>Sent text and line feeds (LF)</p></li>
  </ul>
  
  <p>According to the docs, line spacing should take effect on page mode, but it's not working. Only works outside "page mode".</p>
  
  <p>Any ideas?</p>
