Printing Screen In Dos Probram

How do I print my computer screen
I have a old dos program (check) that I run on my old dell computer (running XP) that is programed to print with a dot matrix printer.As I don’t have one anymore I would like to capture the data on the screen and convert it to a onother format like a dot. or PDF that I can print on my bubble jet printer. I can’t use the ctrl -c / ctrl -v function as at the bottom of every page there is “press any key to move on ” which activates before the ctrl -c works.
Hope someone can help.
