    ----------------------------------------------------

    How can I change this to work for a user who's printing to a Windows NT network printer. Thank's.

    Re: Changing page width using Data Report

    Hello,
    This is my code that i reply to your question some weeks before.
    If you want to change the configuration on the WinNT network printer server from the remote workstation, you must login on the user account that has right to do that.
    Because of this, SetPrinter function will fail if the user does not right to change the configuration on that server.

    Bye,
