The .NET Framework includes three print controllers that are derived from PrintController that help accomplish common tasks. The StandardPrintController prints a document to a printer. The PreviewPrintController generates a preview of what the document will look like when printed and is used by the PrintPreviewControl and PrintPreviewDialog classes. The PrintControllerWithStatusDialog provides a printing status dialog during the printing process.

听起来你正在使用PrintControllerWithStatusDialog PrintController.

警告：我无法验证基本的PrintController的行为方式不同.

根据这个MSDN Forum Posting PrintControllerWithStatusDialog是默认值：

他建议这样：

MyPrintDocument.PrintController = new System.Drawing.Printing.StandardPrintController();
