我有一个需要打印的用户控件。 表格只是一个基本的填写表格。我将所有控件放在一个已命名的堆栈面板中，并且打印按钮位于堆叠面板之外，因此按钮不会打印出来。

你可以介意所有的MVVM加载，这是完全分开的。 无论如何，使用后面的代码，我基本上将其添加到我的按钮点击：
PrintDialog prnt = new PrintDialog();
prnt.PrintVisual(PrntFrm, "Initiate Work Request");
这会打印出我的表单（stackpanel），但它并不完全以页面为中心。它位于左上角，一些文本在左侧被截断。
使用PrintDialog方法，如何设置要打印的页面大小，或者只是将可打印表单的内容居中？此外，如何从PrintDialog设置页面方向？
我是否必须设置PrintableAreaHeight/Width，我该怎么做？
答案 0 :(得分：4)
我明白了。
PrintDialog prnt = new PrintDialog();
if (prnt.ShowDialog() == true)
{
Size pageSize = new Size(prnt.PrintableAreaWidth - 30, prnt.PrintableAreaHeight - 30);
PrntFrm.Measure(pageSize);
PrntFrm.Arrange(new Rect(15, 15, pageSize.Width, pageSize.Height));
prnt.PrintVisual(PrntFrm, "Work Request");
}
用于纵向屏幕。尺寸可能会根据打印所需的数量而改变
和
PrintDialog prnt = new PrintDialog();
if (prnt.ShowDialog() == true)
{
prnt.PrintTicket.PageOrientation = System.Printing.PageOrientation.Landscape;
Size pageSize = new Size(prnt.PrintableAreaWidth + 30, prnt.PrintableAreaHeight + 300);
PrntFrm.Measure(pageSize);
PrntFrm.Arrange(new Rect(15, 15, pageSize.Height, pageSize.Width));
prnt.PrintVisual(PrntFrm, "Job Card");
}
是为了风景。再次，需要时尺寸会发生变化
