For whatever reason, at least on 3.0.4 you cannot remove
a printer _driver_ once added via windows.  I removed the
driver files manually and then used tdbtool to remove
reference to the drivers.  The printer is still defined
in ntprinters.tdb.  I expect windows to not be able to
recognize the printer and prompt me to find the drivers.
Instead windows explicitly says the drivers for printer
"HP 4050tn PCL 6" cannot be found. Even when you point
windows to the correct driver it would respond with "cannot
locate suitable driver".  That description was found in
ntdrivers.tdb not ntprinters.tdb.  Once I removed it from
ntdrivers.tdb the same problem resulted.  To fix it I was
forced to install the driver (not the printer) into samba
(via windows).

Here is the ntprinters.tdb record after I removed the driver
reference in ntdrivers.tdb.  I do not see the driver name
stored as you say it is.
