    Syntax
    'Declaration
     
    
    Public Function PrintGetPaperWidth() As Single
    public float PrintGetPaperWidth()
    public function PrintGetPaperWidth(): Single; 
    public function PrintGetPaperWidth() : float;
    public: float PrintGetPaperWidth(); 
    public:
    float PrintGetPaperWidth(); 

    Return Value

    The paper width, in inches. Please always use the GetStat method or the PrintGetStat method to determine if this method has been successful.
    Remarks
    We strongly recommend using the GetStat method or the PrintGetStat method to identify the specific reason for the method's failure.

    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.
