Thank you to everyone who responded to my question.  My goal was to find
out how to directly talk to the LPD program, and from what RFC 1179 told
me and what the source code from uunet.uu.net told me, I was able to write
a program that is what I call MLPD, or Multiple Line Printer Daemon.
It works by a slight modification to the queueing/printing setup, and
requires no installation of a new package, no filters, no sockets, nothing
above what comes with either 4.3BSD or System V, and even runs smoothly.  
It's just a single daemon program that monitors the printers more accurately
for a better selection of printer files, using the existing lpd program
to get information from.

If anyone wanted to know what I did, or would like to see this program in
its finished state (Another 2 weeks...I have to take care of school first),
please let me know.
