The GDI, or Graphical Device Interface, is the Windows software interface responsible for rendering images and fonts and sending them to external devices such as printers and monitors. Many manufacturers make low cost Windows GDI printers, GDI printers can not render images and fonts themselves, but instead depend on the GDI to render the images and text they print. Because GDI printers are not capable of rendering and preparing images and fonts for printing on their own, you can not use a GDI printer to print from DOS operating systems. To print in DOS, you need a PCL printer.
