[Pkg-cups-devel] Bug#343192: cupsys: infrastructure for dvi autodetection and printing missing.

[Wilfried Goesgens]

Package: cupsys
Version: 1.1.23-12
Severity: serious
Tags: patch
Justification: dvis can't be printed automagically like that.

with some magic cups can be convinced to directly print dvi files. 
i achieved this with:
* adding to mime.convs:
application/x-dvi	application/postscript  33  dvips
* adding to mime.types
application/x-dvi       dvi contains(0,2048,"TeX output")

creating a tiny shellscript in /usr/lib/cups/filters/dvips
#!/bin/bash

# See if we have a filename on the command-line...
if test -z "$6"; then
TMPFILE=`mktemp`
cat >$TMPFILE
	ifile="$TMPFILE"
	else
	        ifile="$6"
		fi
		# try to figure out the dpi's...
		DPI=`cat $PPD |grep -i "resolution " |tail -n 1|sed -e
		"s;\*Resolution.*dpi/;;" -e "s; DPI.*;;"`

		ARGS="-D $DPI "
		if test "$DPI" -gt "400"; then 
		 ARGS="$ARGS -Z "
		 fi
		 echo INFO: Starting dvips. 1>&2
		 echo DEBUG: Running /usr/bin/dvips $ARGS -f \< "$ifile"
		 1>&2

		 exec /usr/bin/dvips $ARGS -f <"$ifile"
		 rm -f $TMPFILE
