I am learning C++, coming from K&R C.  I have the follwoing snipet of code that won't work properly.  Maybe you can assist.

#include <fstream.h>
#include <process.h>

ofstream printer;

printer.open("PRN");

char onechar;

printer << "This is the beginning."
        << '\f'
        << flush;

//print file

Wont't print to the printer.  What is wrong?  

Thanks.

I made your code snippet into a program, and it compiled and printed just fine for me.  I use Visual C++ 5.0 under Windows 95.  Here's the program that I ended up using:

#include <fstream.h>
#include <process.h>

void main()
{
   ofstream printer;

   printer.open( "PRN");
   char onechar;

   printer << "This is the beginning."
      << '\f'
      << flush;
}

Maybe your call to open() is failing.  You can try to see if it worked by calling the rdstate() or bad() members of your printer object.
