print out to a printer, need help

So i'm done with the homework, except for a piece that will optionally print out to a printer. Now unfortunately, I was late for that lecture. Is the professor literally asking the C++ program to print out, as if from a phyiscal printer? (Printing the output on a piece of paper?) If so, how would I go on to do so? It says exactly "The program will optionally print a printer"

I do have the rest of the homework done, fyi

Code:

#include <iostream>
#include "headertime.h"
#include <fstream>

using namespace std;

int main()
{
    char chrAnswer;
    MultiplyMatrices clsMatrix;
    
    cout << "The Matrices are setup as follows:" << endl << endl;
    cout << " __            __     __             __ " << endl;
    cout << "|   x1  x2  x3   |   |   y1  y2  y3    |" << endl;
    cout << "|   x4  x5  x6   |   |   y4  y5  y6    |" << endl;
    cout << "|   x7  x8  x9   |   |   y7  y8  y9    |" << endl;
    cout << " __            __     __             __ " << endl  << endl << endl;
    
    do
    {
        clsMatrix.voidfuncRequestMatrices();
        clsMatrix.voidfuncMultiplyMatrices();
        clsMatrix.voidfuncOutput();
        cout << "If you'd like to use the program again, enter a 'y'";
        cin >> chrAnswer;
    }
    
    while (chrAnswer == 'y');

    system ("PAUSE");
    


    return 0;
}

#endif

Code:

#include <iostream>
#include <fstream>
using namespace std;

void foo ( ostream &where ) {
    where << "hello world\n";
}

int main ( ) {
    foo(cout);
    ofstream x("foo.txt");
    foo(x);
    return 0;
}

If you modify the output function to take a reference to a stream, then you can send the output wherever you want.
The actual name of your printer device varies from OS to compiler.
