windows 2000 printing problem

I have a Delphi 4.0 client/server application where the server runs on
NT4.0
and the clients run on Windows 95,Windows 98 , or NT.  Recently a few
Windows 2000
professional versions have shown up as clients.  The application runs
fine under Windows
2000 until they want to print something via a QReport component.  The
client gets errors like Access violation
or Priveleged Instruction.

Any ideas or solutions?

Thanks,
Dustin
