Why does this piece of code make text center align?
<p>I am doing some Android programming for a receipt printer from Star Micronics. In the sample code it provides, there is a line I do not quite understand. I am puzzled by the fact that it is somewhat linking to assembly language or some sort of machine specific instructions.</p>

<pre><code>ArrayList&lt;Byte&gt; list = new ArrayList&lt;Byte&gt;();
Byte[] tempList;

// Alignment (center)                   
list.addAll(Arrays.asList(new Byte[]{0x1b, 0x1d, 0x61, 0x01}));
</code></pre>

<p>Can someone tell me how that line achieves the center alignment?</p>
