One of the best LPD print spoolers is LPRng. The method of installation depends on your distribution; see Part 1 of the LPI 102 series for details on installing software packages in either Red Hat or Debian.

Once it's installed, the print spooler daemon (officially the Line Printer Daemon) can be run from the command line. Log in as a normal user and try:

$ /usr/sbin/lpd --help
--X option form illegal
usage: lpd [-FV] [-D dbg] [-L log]
 Options
 -D dbg      - set debug level and flags
                 Example: -D10,remote=5
                 set debug level to 10, remote flag = 5
 -F          - run in foreground, log to STDERR
               Example: -D10,remote=5
 -L logfile  - append log information to logfile
 -V          - show version info

Now that the daemon is installed, you should make sure that it's set up to run automatically. Your distribution's LPRng package may have set this up for you already, but if not, see Part 4 of the LPI 101 series for information on using runlevels to start daemons such as lpd automatically.
