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
