I recommend doing a search of the board using print as the keyword.

Basically, there is no standard way to print with a printer in C++. I have seen a solution where the output stream is redirected to the printer rather than the screen. I have seen where "LPT1", or whatever port your printer is on, is used as a filename to associate with an fstream thereby using the printer as a file. I have also seen where the data is sent to a file, then a different program is called, and that program has a print function that can be ued to print the data. You may find other solutions by searching the board, too.

Try something like this, assuming you're using "print" in a generic form, as in "print to the screen":

#include <vector>
#include <cstdio>

using namespace std;

int main() {
    vector< float > prices;
    vector< string > names;

    // Code to fill in vectors should go here

    float sum = 0.0;

    vector< float >::const_iterator curPrice;
    vector< string >::const_iterator curName;

    for (curPrice = prices.begin(), curItem = desc.begin();
             curPrice != prices.end() && curItem != desc.end();
             curPrice++, curItem++ ) {
        printf("%-20s  $%6.2f\n",(*curItem).c_str(),*curPrice);
        sum += *curPrice;
    }
    printf("%20s  $%6.2f\n","Total:",sum);
}
