How to print something in WPF without using controls?

Question

I'm newbie in WPF and I'm trying to print student's exam papers using WPF and I'm creating exam papers using System.Drawing.Graphics and now I want to print them.

But it seems every printable thing in WPF is somehow a control. I have two problems:

1. I don't know how can I print something that I've created via Graphics Like WinForms PrintDocument (that has it's own problems)
2. I don't know how to create my exampaper in WPF like what I did with graphics.

would you help me with any of theses questions?

您可以利用PrintDocument类，而不是WPF特定的类。此类允许您将输出发送到打印机。应该处理PrintPage事件，您可以使用PrintPageEventArgs获取Graphics上下文;用于将检查绘制到打印机输出。这被认为是Winforms的打印方式。

WPF增强了printing命名空间提供的System.Printing支持。这些打印服务用于管理打印作业，发现打印队列和配置的打印机。 WPF中的打印通常通过生成XPS文档来执行，利用XpsDocumentWriter类＆amp;方法。但是，由于使用了System.Drawing.Graphics，因此也可以使用GDI打印，这是您可能需要的。请参阅GDI打印路径部分here。
