Hello Micheal,
you just have to convince your printer, that it gets a .ps file -
add these two lines ahead of your .eps file:
%!PS-Adobe-1.0
save [ /showpage {} def
and append
cleartomark restore
showpage
at the end. We use the following little shell script ( called eps2ps)
#!/bin/sh
if [ $# -le 0 -o $# -gt 2 ]; then
echo usage: `basename $0` file.eps [ file.ps ] >&2
exit 1
fi
if [ ! -r $1 ]; then
echo Can\'t read file $1. >&2
exit 1
fi
epsfile=$1
output=""
if [ $# = 2 ]; then
output=$2
fi
(
cat <<EOF
%!PS-Adobe-1.0
save [ /showpage {} def
EOF
cat $epsfile
cat <<EOF
cleartomark restore
showpage
EOF
) | (
if [ "$output" = "" ]; then
cat
else
cat >$2
fi
)

As circuitous as this is, I learned that I can do this with ImageMagick:
convert file.eps file.pdf && convert file.pdf file.ps
Going through PDF in the middle causes the final Postscript file to keep
the vector information rather than changing it to raster image. The odd
thing is that the simpler command causes the PS created to be a raster
image.
convert file.eps file.ps
Strange behavior if you ask me.
-Mike
