If that is all your filter contains then it is probably not enough.
You are not cat(1)'ing the file to be printed. Try this
#
# Plain text or HP/PCL, so just print it directly; print a form
# at the end to eject the last page.
#
printf "\033&k2G" && cat && printf "\033&l0H" && exit 0
If you want to be able to print PS as well then use this filter
(you'll need ghostscript installed and will probably have to change
the ghostscript options, these are for an HP 610C):
#!/bin/sh
#
# hpif - Simple text input filter for lpd for HP-PCL based printers
# Installed in /usr/local/libexec/hpif
#
# Simply copies stdin to stdout. Ignores all filter arguments.
# Tells printer to treat LF as CR+LF. Ejects the page when done.
# printf "\033&k2G" && cat && printf "\033&l0H" && exit 0
# exit 2
#
# Read first two characters of the file
#
read first_line
first_two_chars=`expr "$first_line" : '\(..\)'`
if [ "$first_two_chars" = "%!" ]; then
#
# It is PostScript; use Ghostscript to scan-convert and print it.
#
# Note that PostScript files are actually interpreted programs,
# and those programs are allowed to write to stdout, which will
# mess up the printed output. So, we redirect stdout to stderr
# and then make descriptor 3 go to stdout, and have Ghostscript
# write its output there. Exercise for the clever reader:
# capture the stderr output from Ghostscript and mail it back to
# the user originating the print job.
#
exec 3>&1 1>&2
/usr/local/bin/gs -dSAFER -sPAPERSIZE=a4 -dNOPAUSE -q \
-sDEVICE=cdj550 -sOutputFile=/dev/fd/3 - && exit 0
else
#
# Plain text or HP/PCL, so just print it directly; print a form
# at the end to eject the last page.
#
printf "\033&k2G" && echo $first_line && cat && \
printf "\033&l0H" && exit 0
fi
exit 2
