When sharing the Black Ice Printers using Group Policy, please make sure you also add the Black Ice Printer Driver’s certificate to the client systems.
You can find the certificate in the installation directory of the Black Ice Printer Driver:
c:\Program Files\Black Ice Software LLC\<DRIVERNAME>\Driver\Black Ice Software LLC.cer
The certificate must be installed into “Trusted Publishers” on the client system’s “Local Computer” store, and not for the user.
