Hi Guys.

Not sure if this forum deals with the electronic side of programming? I basically want to make a money counting machine thats connected to a PC. I will be using a universal hopper to count any size coin.

My problem is, i don't know how to output to the printer port or USB. I have wrote the following simple code to try and show what i mean.

Any help is much appreciated as always. If i'm asking the wrong kind of question please let me know
Code:
#include<stdio.h>

int main()
{
    int coins;
    char answer='y';
    
    while(answer=='y')
        {
        printf("Please input how many coins you want counting out.\n");
        scanf("%d",&coins);
        fflush(stdin);
    
        while(coins>0)
            {
            printf("Output %d coins.\n",coins);/*This is where i need to output to the printer port*/
            coins--;
            }
            printf("Do you want to count more coins?\n");
            answer=getchar();
            if(answer=='n')
            
            break;
        }
    return(0);
}
