samba - Nov 2011 - Conversion Error in migration of printer drivers from Windows seven 64 to Samba PDC 3.5.11

I get problem migrating printer drivers from Windows seven 64 bits
workstation  to Samba PDC 3.5.11

The driver works fine on the workstation

The migration command
net -d 4 rpc printer MIGRATE DRIVERS XeroxM24 -S xxx.xxx.xxx.36 -U
'username'

returns the messages:

convert_string_internal: Conversion error: Illegal multibyte sequence
(......)
ndr_push_error(5): Bad character conversion
cannot add driver: DOS code 0xb75c1223

All the driver files are copied on the samba server after the net rpc
command and the size of each is the same between workstation and samba
server.
The driver is not installed in the printing tdb files.

enumdrivers in rpcclient does not list anything.

Is the driver faulty or not supported by Samba ?
What can I do ?


Below is the end of level 4 debugging output of net rcp command.
