在条码打印中经常需要把条码打印到文档里的指定位置，Barcode Professional SDK for .NET条码控件可以帮助开发人员轻松实现该功能，打印指定大小和指定区域的条码，具体如下：

private void printDocumentObject_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)

{

    //Create a Barcode Professional object

    BarcodeProfessional bcp = new BarcodeProfessional();

    //Barcode settings

    bcp.Symbology = Symbology.Code39;

    bcp.Code = "123456789";

    //...

    //Print the barcode at x=1in, y=1in using DrawOnCanvas method

    bcp.DrawOnCanvas(e.Graphics, new PointF(1, 1));

}
