PrintSetColorMode Method (GdViewer)

In This Topic

Sets up the printer color mode setting of the active printer. This property determines whether the output will print in color or in monochrome.

Syntax

Visual Basic
C#
Delphi
JScript
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Function PrintSetColorMode( _
   ByVal ColorMode As PrinterColorMode _
) As GdPictureStatus

public GdPictureStatus PrintSetColorMode( 
   PrinterColorMode ColorMode
)

public function PrintSetColorMode( 
    ColorMode: PrinterColorMode
): GdPictureStatus;

public function PrintSetColorMode( 
   ColorMode : PrinterColorMode
) : GdPictureStatus;

public: GdPictureStatus PrintSetColorMode( 
   PrinterColorMode ColorMode
)

public:
GdPictureStatus PrintSetColorMode( 
   PrinterColorMode ColorMode
)

Parameters

ColorMode: A member of the PrinterColorMode enumeration. The new value of the active printer color mode setting.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks

It is recommend to use the GetStat method or the PrintGetStat method to identify the specific reason for the method's failure, if any.

Just to remind you that the active printer is the printer identified by the PrintGetActivePrinter method or set by the PrintSetActivePrinter method and it is dedicated to executing all subsequent print jobs using this class as well as utilizing all by you altered printer settings.
