When setting up a network printer in AIX, using remote, standard
processing, raw1, etc. it appears that lpd is listening on port 515.
It also appears that AIX or lpr is listening or sending on ports
1023/1022/etc. Does anyone know of what ports lpr/lpd use and it is
documented.

The port that lpd listens is 515. You can confirm it by chceking in
/etc/services .

But while sending the print requests to print server/Remote printer it
sends through some random ports, where in you can restrict that port to
be within 1024.

You can have a better view if you enable the debug trace as well as
the iptrace.
