title: Scanning Multiple pages using (py)twain
body: <p>Here is my code:</p>
  
  <pre><code>import twain
  for i in range(10):
      twain.acquire(str(i) + ".jpg", ds_name=b"B110,192.168.1.112 TWAIN",
                    dpi=200, pixel_type='gray', bpp=8, show_ui=False)
  </code></pre>
  
  <p>I assume that each <code>acquire</code> calls a scan to the scanner but that is not the case </p>
  
  <p>How can I scan multiple pages using pytwain?</p>
  
  <p>Thanks</p>
