Both and pointed out two common routes: try to send output straight to a printer device, or grab text from the IDE and print it. Both can work, but there are cleaner, more repeatable options that avoid device-specific hacks or manual copy/paste.

The simplest and most reliable approach is to capture stdout into a text file, then print that file. From a command prompt run the built executable and redirect output:

myprogram.exe > output.txt

Or perform the same inside code by reopening stdout to a file:

#include <cstdio>

int main() {
    freopen("output.txt", "w", stdout);
    puts("Program output here");
    return 0;
}

See the docs for freopen for details: freopen on cppreference. Once you have output.txt you can open and print it from Notepad or any editor.

If you need to send text straight to a printer from code (rather than to a file), use the Windows printing APIs or an application-level print call instead of poking at device names. For simple cases you can ask the OS to print the text file (it launches the registered handler) with the ShellExecute "print" verb, or use the Win32 GDI printing sequence (StartDoc/StartPage/EndPage/EndDoc) or MFC printing classes for formatted output. Microsoft documentation: ShellExecute (print) example and . Note: printing plain text will lose console styling and may need font/line-wrap handling, so writing to a file first and printing that is often the quickest, most portable route.

>How can we print the output of the program
Print to a printer device, you mean? There are probably issues involved that you aren't aware of, so writing directly to a printer stream isn't the best idea. It would be much better to search your documentation to find a nice, happy way of printing data. There are several naive approaches though. The first is using the nonstandard stream stdprn, though I don't believe it's available in Visual Studio 6. The other common option is opening your own stream with the files "PRN" or "LPT1", which "PRN:" and LPT1:" as alternatives if the first two don't work. But if you can find a printer interface API in your compiler's libraries, that would be preferable.
