Exactly what I said. He might need the source to port to a machine that
has internet support, but not lpr/lpd, which I can't imagine, but might
conceivably exist. For example, AIX does have some internet support, but
since it is System V based, might use lp rather than lpr.

? We set up our system V machines to do uux to a "print server", a
? BSD machine that knew how to get to all the printers.  It works
? fine.  No porting required.

Good move. Since I intent to remain adamantly ignorant of uucp (I suppose
I should modify my opinions a bit, but am spoiled by the internet), I
didn't even think of that.

? I have one machine that runs BSD and SYSV concurrently.  It has
? both lp and lpr, but I didn't want both deamons talking to the
? same device at the same time.  Hacking the interface script in
? the lp command to pipe through lpr solved the problem.

Isn't that what I said above?
