I'm printing to a printer shared on a WindowsXP machine on my LAN. I also know that my linux printing system works because I can print to an IPP shared printer via MacOS X (though admittedly that is a different protocol).
I have a password-protected user account on the XP machine.
In the KDE Add Printer Wizard ('s SMB Shared Printer) I can browse my workgroup as 'Anonymous' and see my print server computer, though I can't select it and see the shared printers because I'm not authenticated (NT_STATUS_ACCESS_DENIED).
However, when I enter my username and password in the browser I can't even see the computer! Same for the guest account (though there is a passwordless 'Guest' account on the XP machine, possibly conflicting?).
I suppose I could try to enter the settings manually, but I don't know how to format the Samba URL
