Don't forget the fact that you jumped from DOS to Windows. Drawing a single character on a DOS screen or to a printer involved far less data flow. With Windows the single character is drawn with many pixels. The single character is sent through the Windows printer driver which also makes a graphic representation of that character. These processes take much longer than in DOS. There's no way for newer to be necessarily faster as far as that is concerned.
