Does the normal BiPrnDrv.ocx work with the Monochrome Printer Driver for Terminal Services?
The Black Ice terminal server printer driver has its own BiPrnDrv.ocx which internally is different from the non terminal server version.
The BiPrnDrv.ocx for terminal servers is distributed in the RTK that you receive with the release version of the terminal server printer driver. Also, the terminal server RTK contains samples written in Visual Basic, Delphi, etc. to show how to use the terminal server version of the BiPrnDrv.ocx.
