This was my suggestion!

Then maybe sed is not in the path as seen by lpd.
Try a full path: i.e. /usr/bin/sed in place of sed.

I should have thought of this possibility in the first place.
(I believe the 'cat' should be superfluous)

For the record, my original suggestion was:

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
