samba - Jan 2010 - Windows printer driver setup - editing .TDB files

Hi Everyone,
I'm running Samba 3.3.4 on FreeBSD with Windows XP clients.

Short version of question:  How do I get Samba to "forget" about a
printer and its drivers, so I can install a fresh version?

A while back, I set up a few printer shares, and used the "add printer
wizard" to upload the windows drivers to Samba (just like it's spelled
out in the HOWTO book, "Chapter 21. Classical Printing Support") and
everything went well.

Now I'm trying to add another printer, and I can not get the thing to go
into the "add printer wizard".  It acts like it already has a driver
for this printer.   Per the instructions, I browse to the Samba "Printers
and faxes" folder, and enter "properties" for the printer share,
but no APW comes up.

I've tried renaming the share; same thing.  I figured out tdbtool and have
gone through the files trying to remove any references to the share name, but no
luck.

What am I missing here?

-Thanks, Wayne
