OK, you do the following:
a) set up this script
#!/bin/sh
type=`file - `;
perl -e 'rewind(STDIN);'
case "$type" in
*text* ) break;;
* ) /usr/bin/printf "Your print job is not a text file\n\r";
exit 0;
;;
esac
exec /products/LPRng/libexec/filters/lpf
This is basically how all the 'magic filters' do it.
