printing - How to print a BMP from file or HDC

Question

I am trying to add printing capability to my Windows app. So far, I have succeeded in (1) painting the image into an HDC; (2) saving it as a BMP file; (3) creating a BITMAPINFOHEADER and pixmap in memory; and (4) creating an HBITMAP object.
How can I send any of these to my laser printer? (I don't want to use any third-party app, but rather do it using API calls).
Any suggestions?

看起来您需要使用 XPS Document API，除非您的打印机驱动程序接受 bmp 文件作为输入（这似乎不太可能）。另一种选择是将输出生成为 postscript 文件（许多打印机接受 .ps 文件作为输入；至少，他们曾经这样做过。检查打印机的文档）。

如果您选择 XPS 文档路径，请在此处查看文档：https ://docs.microsoft.com/en-us/windows/win32/printdocs/documents 显然，在 Windows 中，您现在可以将 XPS 文档发送到您的打印后台处理程序，它应该可以工作。我没有测试过这个。
