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?

It looks like you will need to use the XPS Document API, unless your printer driver accepts bmp files as input (which seems unlikely). Another option is to generate output as a postscript file (many printers accept .ps files as input; at least, they used to. Check your printer's documentation).

If you choose the XPS document path, have a look here for the documentation: https://learn.microsoft.com/en-us/windows/win32/printdocs/documents Apparently, in Windows, you can now just send XPS documents to your print spooler, and it should work. I have not tested this.
