pdfpre - a CUPS prefilter to "normalize" PDF documents
===============================================================
This filter makes a (nearly) identical copy of the input PDF
without the use of "object streams" which are a feature of
PDF versions 1.5 or greater and compress the parts of the
PDF document which are written as plain text by default.
Using this filter permits printing of PDF documents which
are otherwise not printed as expected by PDF interpreters
that do not understand these "object streams".
The filter must be activated by the statement
*cupsPreFilter: "application/pdf 20 pdfpre"
in the printer's PPD file.
