Example





In This Topic
    PrintSetActivePrinter Method (GdViewer)
    In This Topic
    Sets the printer, identified by its name, as the active printer, in other words makes it the currently selected printer, which is subsequently used when printing the document displayed in the GdViewer control. The specified printer is used to execute all next print jobs using the print methods of this class, if not set otherwise, without affecting any other installed printers.

    You can use the PrintGetActivePrinter method to retrieve the currently selected printer, denoted as the active printer for print methods of this class. At the same this printer utilizes all by you altered printer settings without affecting the installed printers.

    'Declaration
     
    
    Public Function PrintSetActivePrinter( _
       ByVal PrinterName As String _
    ) As Boolean
    public bool PrintSetActivePrinter( 
       string PrinterName
    )

    public: bool PrintSetActivePrinter( 
       string* PrinterName
    ) 
    public:
    bool PrintSetActivePrinter( 
       String^ PrinterName
    ) 

    Parameters

    PrinterName
    The name of the printer you want to set up as an active printer to be used for subsequent printing.
