3.2.5.2.1.4 Sending a Bind Printer Response
The client MUST retrieve from the client printer driver the following fields: Options, DevModeFlags, and Namespaces. It MUST populate the fields of the BIND_PRINTER_RSP message with this information. These fields are opaque to the protocol and are meaningful only for the printer drivers. The return result of the call MUST be sent in the Result field of the response.
