        Reply to: SUMMARY : Printcap spool file

Thanks to Stephen Harris and Gene Rackow for the replies. I have not really
find time to test out but Gene's filter looks pretty promising and seems to be
what I wanted.

From: (Stephen Harris)

It's a filter so the file is on stdin - just "cat" to send it to stdout and
thus the printer

From: Gene Rackow <>

The problem is that the filters get the data on stdin, not as a file name.
Here is a segment of the code I use to pre-precess input. It's not very
nice in that it requires that there is tmp space to copy the spool file,
but it was a quick and dirty hack that works on several systems.
the ps?f filters are all the same script with a case statement to switch
actions on name. There are also some better ways to deal with this
depending on the software that you are using and the type of printer.
I've got a couple that require some real oddities, and this method was
the only one that worked reliably for the lpd spoolers.

while test $# != 0
do case "$1" in
        -c) ;;
        -w*) width=$1 ;;
        -l*) length=$1 ;;
        -i*) indent=$1 ;;
        -x*) width=$1 ;;
        -y*) length=$1 ;;
        -n) user=$2 ; shift ;;
        -n*) user=`expr $1 : '-.\(.*\)'` ;;
        -h) host=$2 ; shift ;;
        -h*) host=`expr $1 : '-.\(.*\)'` ;;
        -*) ;;
        *) afile=$1 ;;
case $prog in
    cat > $tmp
    file $tmp | grep -i -s Postscript
    if [ $s -eq 1 ] ; then
     /usr/local/bin/enscript $PSAVE -q -l -p $ $tmp
      mv $tmp $
    rm -f $tmp ,* gs_*
 psnf) psdit > $
cat $ >$DEV
