# This is a gLSB 1.1 complient start script for LPRng. See
# http://www.linuxbase.org/spec/refspecs/LSB_1.1.0/gLSB/sysinit.html
#
### BEGIN INIT INFO
# Provides: lpd
# Required-Start: $network $remote_fs syslog
# Required-Stop: $network
# Default-Start: 2 3 5
# Default-Stop: 0 1 4 6
# Short-Description: Start lpd to allow printing
# Description: lpd is the print daemon required for lpr to work properly.
# It is basically a server that arbitrates print jobs to printer(s).
### END INIT INFO
# Source gLSB script
. /lib/lsb/init-functions
# replace with the path you installed LPRng's lpd into:
LPD_PATH=/usr/sbin/lpd
test -x $LPD_PATH || exit 5
# Return values acc. to LSB for all commands but status:
# 0 - success
# 1 - misc error
# 2 - invalid or excess args
# 3 - unimplemented feature (e.g. reload)
# 4 - insufficient privilege
# 5 - program not installed
# 6 - program not configured
#
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signalling is not supported) are
# considered a success.
