Can you please tell me I shall place the file "LTP1" in order for WinXP to
grap it and starts printing? C:\LTP1 or C:\windows\ltp1 or ...?

Best regards

problem"?

The OP (Klaus Jorgensen) should answer your question, but I believe he was
referring to a DOS programming technique, rather than to simply put an ascii
file somewhere.

I misunderstood your question because Printfil does exactly this: you put an
ascii file somewhere on disk (or let Printfil capturing the LPT output) and
Printfil automatically redirects it to any Windows printer.

If you want to give it a try, you can find a free trial to download at our
web site.

Regards,
Davide.

No path, no drive letter, just tell the DOS app to print to a file
called LPT1. Well, it's actually a predefined device name and not a
file name.

(...or in plain Danish:
Drev og sti er ikke nødvendigt, og filen skal ikke laves i forvejen da
navnet faktisk indikerer en forud defineret enhed og ikke en fil.)

Thanks Klaus, I really owe you a beer. You have just solved a major problem
for me. Why isn't this solution highlighted anywhere?

best regard og tusind tak
