开始打印的代码，我相信是造成我们麻烦的是
Size tempSize = (Size)(cPaperSize.SelectedItem as ComboBoxItem).DataContext;
Size size = new Size(PageOrientation.Value == System.Printing.PageOrientation.Portrait ? tempSize.Width : tempSize.Height,
PageOrientation.Value == System.Printing.PageOrientation.Portrait ? tempSize.Height : tempSize.Width);
GlobalPrintDialog.PrintQueue = new PrintQueue(new PrintServer(), cPrinter.Text);
我希望我们选择A5，它会告诉打印驱动程序打印A5，
如果我们选择自定义的“用户定义”纸张尺寸，它将告诉打印机选择了哪种尺寸。而不是每次都将其固定在A4上
我们似乎无法在打印对话框之外设置纸张尺寸。
