The current Black Ice printer drivers will automatically remove existing printer settings.
Previous printer settings can be manually removed by going to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\Black Ice PRINTER NAME
Delete the "Default DevMode" value.
Also go to the following:
"HKEY_CURRENT_USER\Printers\DevModePerUser", "HKEY_CURRENT_USER\Printers\DevModes2", and "HKEY_CURRENT_USER\Printers\Settings" keys and delete all values which contains the name of the printer ("Black Ice TIFF", \\DRIVERS2000\Black Ice TIFF,LocalOnly,DrvConvert, etc)
Also, search the HKEY_USERS (other users than the current user) for the values mentioned above.
