My program need to print a curve, my solution is changing the curve into a picture, and this picture file (xxx.png) can be printed by using the default windows picture printing tool(right click the mouse on top of the file, and select print).

This prints an image file (.png in my case) to a specified printer WITHOUT a dialog box popping up. Also... works without elevated command prompt privileges.
这会将图像文件（在我的情况下为 .png）打印到指定的打印机，而不会弹出对话框。另外...无需提升的命令提示符权限即可工作。

I had a similar problem but I also needed way to control scaling (needed for barcode work) and always have the image centered.
我有一个类似的问题，但我还需要控制缩放的方法（条形码工作所需）并始终将图像居中。
I wrote an Open Source tool called ImagePrintto do just what you want. It's written in VB.Net as a console app. At the moment, it only prints to the default printer.
我写了一个名为ImagePrint 的开源工具来做你想做的事。它是用 VB.Net 作为控制台应用程序编写的。目前，它仅打印到默认打印机。
