How to make the PrtSc keyboard button printing DOS screens directly, through Printfil

At the DOS age, printing the screen content was very easy, just by pressing the PrtSc button on the keyboard (even labeled as Print Scrn, Prnt Scrn, Prt Scrn, Prt Scn, Prt Scr or Pr Sc).

If you do so in Windows, however, you do not get the same result, because the PrtSc button sends an image of the screen to the Windows clipboard instead of sending the screen content to the default printer.

This video shows how to enable the PrtSc button on a DOS program running in Windows, so that it sends the content directly to the printer(s), like in the DOS age.

Let's go:

  • Configure Printfil to capture the LPT1: port
  • and setup LPT_Timeout = 3
  • Reboot the computer!
  • Right-click the DOS program's shortcut and choose Properties
  • In the Misc tab uncheck PrtSc

That's all. Now:

  • Run the DOS program and press the PrtSc keyboard button
  • Printfil captures the DOS screen and you can send it to any Windows printer
