title: How to save an IPython Notebook as PDF?
body: <p>So, as the title say, i'm  having a little trouble saving my notebooks as PDF, 
  when i try:</p>
  
  <pre><code>ipython nbconvert --to latex --post PDF MyNotebook.ipynb 
  </code></pre>
  
  <p>i get the error:</p>
  
  <pre><code>File "&lt;ipython-input-4-329ffed1c22e&gt;", line 1
  ipython nbconvert --to latex --post PDF Presentacion.ipynb
                  ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>and i have no idea how to solve this, plus i also want to save it as a slide, but i get same error, does anyone know how to solve this problem?</p>
