Direct copy to printer port under Win NT

[ivansto]

Hi all,

I need to make a litle program that only copy the
to lpt1 on Win NT.

All is ok with the code, but after starting the printer do not print.

I try to start in MS DOS copy myfile lpt1.

The system reports : 1 file copied and so on, but nothig happen with printer.

The printer is ok and I can print with edit.

Is it possible to use lpt1 directly under NT ?

Many thanks.

Thanks for the answer, but it is not the solution.

I use the sandart ASCII open for file open and all
working well on Win98.

I do not know if it is NT bug or NT setting.

It is not working also on 2000 and NT Workstation.

Many thanks.

Hi,
the code is very simple.

But you can try it with simple MS DOS copy to lpt1.

Regards.
