title: CUPS page accounting with custom filters
body: <p>I got two Konica Bizhub printers and want Windows machines to print via Samba. </p>
  
  <p>The problem is, these printers work with account tracking for copy/scanning. I dealt with it that way: <a href="http://casa.apertus.es/blog/2011/06/howto-account-tracking-konica-minolta-c220-under-linux/" rel="nofollow">http://casa.apertus.es/blog/2011/06/howto-account-tracking-konica-minolta-c220-under-linux/</a> (modified by another post: adding *cupsFilter to the printer PPD).</p>
  
  <p>But now I can't account the printed pages, because every job is accounted with 1. </p>
  
  <p>If I understand everything right, the "<code>pstops</code>" filter has to be applied to count correctly. Is there a way to chain filters?</p>
  
  <p>Another printer managed by CUPS (without custom filters) is accounted correctly and uses the same driver approach (Windows PS driver with printer specific PPD).</p>
