How to print the screen that we created in OpenGL?Is there any direct command for that?
for giving it to printer
There is no direct command.
I believe the method that I’ve used is typical. You’ll have to create an “in-memory” rendering context that is of a resolution that matches your printer resolution (or close). Render to the new RC. Capture the pixel data and print it. I set a limit to the resolution of the in-memory RC because the resolution of most modern printers is much higher than the screen resolution and the in-memory image could get really large.
I have seen sample code on the web for doing this in C++, but I can’t recall the link.
Good luck.

Also, you can capture any window by pressing Alt+PrintScrn and then pasting it into a bitmap. Then you can edit the picture to remove stuff you don’t want, i.e. menus and things that are present if you’re rendering openGL with an SDI or MDI
