Hi all...
First, thank you to Matt Chapman for pointing out why I could not connect to a
non-domain participating machine. I needed to have a local account on that
machine (it wasn't checking back with the domain controllers as I thought it
would). I guess I'm going to have to start venturing out of the UNIX world
and
into the NT one. Scary :-)
Either way, I now successfully am printing to a printer shared on a NT 4.0
workstation from AIX.
Below is the modified smbprint script with documentation. In searching the
archives of this list and others, FAQs, web-sites, etc., I never saw an
explanation of how to deal with the weirdness of AIX printing while using
smbclient. Well, I'm not claiming it's perfect, but here goes.

#!/bin/ksh
# smbprint (for AIX): Print files from a UNIX system running samba to
# a printer shared on another smb serving machine.
#
# Since AIX doesn't use a standard printcap file, this script is modified
# from the one distributed with Samba.
#
# As if there is a standard way of printing in UNIX :-)
#
# The first printer I have done this way in AIX (4.3) has the following entry
# in the /etc/qconfig file:
#
# p02:
# discipline = fcfs
# up = TRUE
# device = dp02
# dp02:
# backend = /usr/local/bin/smbprint p02
# file = FALSE
# header = never
# trailer = never
#
# Technically, since most of the values are the defaults, it could be as
# short as:
#
# p02:
# device = dp02
# dp02:
# backend = /usr/local/bin/smbprint p02
#
# From what I could tell, when AIX calls the backend program, it appends
# the file you are printing to the end of the command. If you feed into
# the lp command from standard in, this is a temporary file in the print
# spool directory (as it is if you use the "-c" option to the lp
command).
#
# In the backend program definition, The "p02" is the name of the
# configuration file for this "service", found in CONFIG_DIR(defined
below).
# In this case, the file /var/samba/print/p02 has:
#
# SERVER=tkt15n3z
# SERVICE=printer02
# USER=print
# PASSWORD=you_dont_think_i_would_actually_tell_you
# TRANSLATE=TRUE
#
# All but the last one are standard smb variables. TRANSLATE is a way I
# have made it so that you only do the CR/LF translation for printers
# that require it. It will do the conversion if TRANSLATE is set to
"TRUE".
# All other TRANSLATE values (or lack of a value) will be ignored.
#
# Security. Well, I could have easily passed all the script variables
# on the backend line in /etc/qconfig, but it bothered me that
# the world-readable qconfig file would contain a password. So, I've
# made this script run setgid (via a wrapper) as printq (please, those
# more intelligent than I, let me know if there is a risk I don't realize
# in doing this). I then protected both write ability to the log and
# read/write to the config files.
#
# Dunce note: Being unfamiliar with NT 4.0, I had a problem initially
# connecting to a machine that wasn't participating in the domain. I
posted
# to the samba@samba.anu.edu.au newsgroup (which you can get more info about
# at http://samba.anu.edu.au/listproc) asking about the problem and got a
# nice response from Matt Chapman asking if I had a local account on
# the machine I was trying to connect to. Since my Win95 pc connected fine
# to the machine without me having a local account on it, I didn't think
# it was required. It was :-)
#
# Thanks Matt.
#
# Any suggestions for improvements/etc? Please send them!
