public GdPictureStatus Print()

public function Print(): GdPictureStatus;

public function Print() : GdPictureStatus;

public: GdPictureStatus Print();

public:
GdPictureStatus Print();

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

Please note that you can use the PrintGetStat method to identify the specific reason for the printing failure.

Just to remind you that you can also utilize both the BeforePrintPage and the AfterPrintPage events using this method.

You also need to be aware that annotations and form fields included in the document are rendered by default using this method when printing.
