Thanks Jeremy for your reply.  I am running on SuSE 11.0 x64 
architecture. From SWAT I got the following version info - version:    
3.2.4-4.7-2210-SUSE-SL11.0   Hope that is correct.

As for my smb.conf, it is configured for my SOHO network at home. Does 
not show the printer share I am actually trying to connect to as that is 
supplied by CUPS. (autoloaded from the printcap file and called tp0.)

My printcap file is -

# This file was automatically generated by cupsd(8) from the
# /etc/cups/printers.conf file.  All changes to this file
# will be lost.

My smb.conf file is shown below -

# Samba config file created using SWAT
# from UNKNOWN ()
# Date: 2009/10/28 12:02:37
