If its the old 16-bit Turco C++ then you can forget it because all the drivers I know of are 32-bit Windows. I don't know how to do it in *nix -- probably postscript or something like that, but that is just a guess.
If you have Win98 I think it can be done. Just run your program and press "Print Scr" button on your keyboard, minimize the Turbo C window, goto MSPaint and paste the image.
It should work out to be fine, but dont know if the same can be done in WinXP. Here you can try out ALT + Print Screen, though I have not personally tested it.
Another way is to press ALT + ENTER when you are in full screen mode of Turbo C to resize the window, then you can use comfortablly use PRINT SCREEN button to capture the whole screen, edit out the part which you require and print it.
One of this is sure to work and if not then dont think anything else will.
