Thanks to all who replied:

The solution I've chosen for the moment is a slight variation
of a script by David Jackson:


#!/bin/sh
if test $# = 0
        then
                filename="-"
        else
                filename=$1
fi

/usr/local/bin/gs -q -dNOPAUSE -sDEVICE=laserjet -r300 \
-sOutputFile=\|"/bin/cat" $filename /usr/local/lib/ghostscript/quit.ps

exit

where /usr/local/lib/ghostscript/quit.ps contains the single word 'quit'.


As an alternative, Wolfgang Steger suggests file redirection:

gs [gs options] -sOUTPUTFILE='cat >&3' files ... 3>&1  2>logfile 1>&2
