Debian and Ubuntu both briefly used a patch (around version 2.5.1 IIRC) that bypassed the pdf2pdf filter. It worked well for simply passing documents that were already in PDF format over to CUPS for output to a PDF spool. However, it completely broke CUPS-PDF's primary functionality which is to convert arbitrary document formats into PDF, and it also prevented users from further manipulating the documents via CUPS-PDF's configuration file options before outputting them to the PDF spool. This resulted in complaints from users who depended upon these features, so I removed the patch. Martin-Éric
