[Samba] Guest printing issue using cups

[Vaughan Roberts]

Hi,
 
I am running Samba.3.0.20b_1 on a FC4 box kernel-2.6_13.1 box with a mixed set
of Win2k, XP clients.
 
I want to enable everyone to print to a local printer on the Linux box as a
guest.  The XP machines can do this, but my Win2k machine insists that I log in
as a Samba user before it will enable me to print.  That's OK when I am logged
into it (although annoying), as I know what to do, but others find this too
difficult for them.
 
I also suffer from the "Can't become connected user!" error messages, though I
seem to be able to connect and do what I need...
 
Here are the relevant parts of my smb.conf file.
 
# Samba config file created using SWAT
# from 127.0.0.1 (127.0.0.1)
# Date: 2005/11/07 09:30:09

Any suggestions as to why this might be happening?
