title: Label printer advancing 8 labels before actually printing simple label
body: <p>I'm just getting started with direct printing via ZPL and am currently connecting to the printer via a TCP socket, using PHP.</p>
  
  <p>Whenever I print a label, whether via the script I've written, or using the Windows based Zebra Configuration client, the printer advances ~8 labels, then prints.</p>
  
  <p>The ZPL I'm using to print the label is below:</p>
  
  <pre><code>^XA
  ^FO50,50
  ^ADN,36,20
  ^FDFront Shelf-2^FS
  ^XZ
  </code></pre>
  
  <p>Since I've had the same results from the configuration app, and via TCP socket, I'm a little stumped.</p>
  
  <p>I have configured the printer (a QLn220) with the correct label size (50mm x 40mm).</p>
  
  <p>I would like some suggestions on how to find out what is causing these extra labels to feed when I print.</p>
