It's nothing fancy. It accepts one filename as parameter, copies this file
to a temporary file - even if it comes from a pipe - and lets gs print
it, using the gs options needed for my type of printer. If anyone can do
this better, let us hear it. You have to modify the script to work on your
type of printer. It's just an example.

#/bin/sh
PRINTFILE=/tmp/temp.ps
if [ -f "$1" ]; then
	PRINTFILE=$1
else
	cat > $PRINTFILE  # if coming from a pipe
fi

gs \
-q -sDEVICE=cdjcolor \
-r300x300 \
-sPAPERSIZE=a4 \
-sOutputFile=/dev/prn \
-dNOPAUSE \
-dBATCH \
$PRINTFILE

rm -f $PRINTFILE
unset PRINTFILE
printf "\x1bE" > /dev/prn  # reset HP printer
exit 0

Maybe it's not very useful on a standard Atari. But what about Milan,
Hades, CT60, Aranym, the Atari Coldfire Project ?
