Transfer Printfile from Printserver directly to Printer

[Martin Vogler]

Hi Guys,
Is there anybody, who can tell me how I can simulate the DOS Command:
Copy filename LPT1
in C++ ?
I have tryed it with the READFILE and WRITEPRINTER commands, but i#ll
get only chunk on the paper.
thanks for any comment

If you want to invoke the DOS shell I think you will need the "system" call.

I don't know about 'simulating' it, but I think that is off topic here
anyway since it involves dos API (if you can speak of that ) calls that
do not have anything to do with C++ itself.

HTH, Jaap

#include <fstream>

int main()
{
std::ifstream file("filename");
std:fstream lpt("LPT1");
char c;
while (file.get(c) && lpt.put(c));
}

It will probably be more efficient if you don't copy each character on its
own, but instead read/write in blocks.

Thanks Rolf for the code, but it doesn't work and I don't know why. I
think I'm to silly to code the problem correctly.
I tried it with two files and it worked but with file and printer
nada:-((( Maybe there is another reason, i code on a laptop without a
parallell port.

Greetings Martin

Rolf Thausend Thanks, now it works pretty good. I've only to tell LPT1
which netprinter I want:
net use LPT1 \\server\printername. In Austria we will say now: "runs
like a bell" )
