Executive summary:

(1) Make sure you have a symlink named 'smb' in /usr/lib/cups/backend/
    pointing to a binary called "smbspool":

       ln -s $(which smbspool) /usr/lib/cups/backend/smb

    Restart cupsd, if you have an older version of CUPS.

(2) Use the backend for a printer named "shared" which is attached to
    an XP PC named "xpbox":

       lpadmin -p your_printername \
               -v smb://xpbox/shared \
               -E \
               -P /path/to/PPD.ppd

    If "xpbox" requires authentication, and is in a different workgroup
    from you, use

       lpadmin -p your_printername \
               -v smb://username:password@workgroup/xpbox/shared \
               -E \
               -P /path/to/PPD.ppd


Read up in "man smbspool"...

(Take note that smbspool is part of Samba, not CUPS.)
