In a previous video, we've seen how to Print from DOS PRN, LPT1: to Windows printers.
However, newer Windows versions may refuse to capture LPT1: if it's physically present in the hardware.
In this video, we see 2 possible solutions to that problem.

The Problem: Capturing a physical LPT1 fails:

Capture the DOS LPT1: port
Error: LPT1 is physically present

1st Solution: Run Printfil as Administrator:

Close Printfil and run it as Administrator
Capture LPT1: again
No errors
Print from DOS to LPT1:

2nd Solution: Disable the hardware LPT1 port:

Close Printfil and run DevMgMt.msc
Disable the parallel port (LPT1:)
Run Printfil as normal user and capture LPT1
It works well
