printing command.

can anybody tell me the command to print out a variable straight to the printer please.
p.s (not 'print screen' or 'screen dumps')

thanks.

Which OS/Compiler?
What type of printer, and what sort of port is it plugged into?
What type of program - console or GUI ?

I came across this
http://support.microsoft.com/default...kb;en-us;23976

im using dev-C++, this is for my AS level coursework project! 'village hall'. have XP at home but NT at school, so needs to work on both.
using the DOS box.
i just need a command which can print my variable text to a printer (reciept).

I am trying to do the same thing. I have tried those tips and nothing happens. These are the codes that I have tried

Code:

---

#include <stdio.h>
#include <iostream>

using namespace std;

int main()
{
    FILE *stream;

    stream = fopen("LPT1", "w");
    fprintf(stream, "a line of text\n");
    fclose(stream);
    cin.get();
    return 0;
}

---

Code:

---

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ofstream printer("lpt1");
    printer << "a line of text\f" << flush;
    cin.get();
    return 0;
}

none of these work for me. no errors just nothing prints. I know the printer is working right because I tested it.

With an HP Deskjet Printer on lpt1

Does this work?

Code:

---

C:\>echo Hello, World! > lpt1

If so, you can just redirect the output of your program from the command line:

Code:

---

C:\>program > lpt1

---

BTW, some compilers define a stream called stdprn.

Code:

---

fprintf(stdprn, "a line of text\n");
