c# - PrintForm 裁剪表单的右侧

Question

好的，所以当我发出

this.printform1.print();

相关代码

            this.printForm1.DocumentName = "document";
              this.printForm1.Form = this;
               this.printForm1.PrintAction=System.Drawing.Printing.PrintAction.PrintToPreview;
                 this.printForm1.PrinterSettings =((System.Drawing.Printing.PrinterSettings)(resources.GetObject("printForm1.PrinterSettings")));
                   this.printForm1.PrintFileName = null;

命令 printpreview 并显示打印的文档，它从右侧修剪，边缘很大，我似乎找不到原因。
