title: Converting PDF to PCL via Ghostscript only without colour?
body: <p>We are trying to convert some PDF files into PCL files using Ghostscript.
  The commandline we're using:</p>
  
  <pre><code>gswin32c -dBATCH -dNOPAUSE -sDEVICE=pxlcolor \
   -f ..\examples\pu.pdf -sOutputFile=..\examples\pu.pcl
  </code></pre>
  
  <p>This generates a black&amp;white PCL file. </p>
  
  <p>Please help, what's wrong?</p>
