Since it is a binary file I'm not sure how well it will go (I guess it is= PCL for which I can't remember off hand the coding) but if you canedit it wit= h vi and still get a reasonable result there is a good chance sed will manage = it. Try replacing the filter line: printf "\033&k2G" && cat && printf "\033&l0H" && exit 0 with printf "\033&k2G" && sed -e 's/@PJL SET DATE=3D[0-3][0-9]-[01][0-9]-20= [0-9][0-9]/@PJL SET DATE=3D01-12-2000/g' && printf "\033&l0H" && exit 0 (This assumes that day and month are always encoded as 2 digits each) It might not work but I think it is at least worth a try ;-) Please let us know what happens. If it doesn't work a simple filter written in C should easily do the tric= k. > > Other pertinent information I left out.
