Subject: [PATCH] import initiale provient de /usr/lib/cups/filter/pdftops

il ne fait que parser les arguments de type lp commencant par "pdf-" pour
les donner a pdftops.

+# pdftops.pl - wrapper script for xpdf's pdftops utility to act as a CUPS filter
+# ==============================================================================
+# 1.00 - 2004-10-05/Bl
+#	Initial implementation
+#
+# Copyright: Helge Blischke / SRZ Berlin 2004
+# This program is free seoftware and governed by the GNU Public License Version 2.
+#
+# Description:
+# ------------
+#	This program wraps the pdftops utility from the xpdf 3.00 (and higher) suite
+#	to behave as a CUPS filter as a replacement for the original pdftops filter.
+#
+#	The main purpose of this approach is to keep the properties of a PDF to be
+#	printed as undesturbed as possible, especially with respect to page size,
+#	scaling, and positioning.
+#
+#	The pdftops utility reads a configuration file 'pdftops.conf' in the 
+#	CUPS_SERVERROOT directory, which must exist but may be empty. The sample
+#	configuration file accompanying this program sets the defaults which
+#	seem plausible to me with respect to high end production printers.
+#
+#	To give the user highest possible flexibility, this program accepts and
+#	evaluates a set of job attributes special to this filter, which are 
+#	described below:
+#	
+#		pdf-pages=<f>,<l>
+#				expands to the -f and -l options of pdftops
+#				to select a page range to process. This is independent
+#				of the page-ranges attribute and may significantly
+#				increase throughput when printing page ranges.
+#				Either of these numbers may be omitted.
+#
+#		pdf-paper=<name>
+#		pdf-paper=<width>x<height>
+#				<name> may be one of letter, legal , A4, A3, or match;
+#				<width> and <height> are the paper width and height
+#				in printers points (1/72 inch). This expands to
+#				either the -paper or the -paperh and -paperw options
+#				of pdftops
+#
+#		pdf-opw=<password>
+#		pdf-upw=<password>
+#				expand to the -opw and -upw options of pdftops,
+#				respectively and permit printing of password
+#				protected PDFs.
+#
+#		pdf-<option>	where <option> is one of
+#				level1, level1sep, level2, level2sep, level3, level3sep,
+#				opi, nocrop, expand, noshrink, nocenter.
+#				See the pdftops manpage for a detailed description of
+#				the respective options.
+#
+#	All other pdftops commandline options are refused.
+#
+#	When printing from STDIN, the program copies the input to a temporary file
+#	in TMPDIR, which is deleted on exit.
+#
+#	The return code of the pdftops utility, if nonzero, is used as the exit code
+#	of this program; error messages of the pdftops utility are only visible
+#	if 'debug' is specified as LogLevel in cupsd.conf.
+
+#
+# Site specific parameters - modify as needed
