    accessing printer

    Hello,

    hope somebody can just point me in the right direction.

    For all of my projects I've just been saving output whch is to be printed, to a text file. And later printed it out using note pad or word pad.

    I know that there must be a way of me actualy controling the printer myself but have no idea how.

    This has no bearing on my studies, I just realy need to know.

    The compiler that I'm using is "Dev C++", and the printer I'm trying to access is "lexmark Z42".

    Is this about controling the port that the printer is using or do I have to interact with the printers own driver?

    This works for text only and black and white.

    Code:
    #include <stdio.h>
    
    int main(void)
    {
            FILE *prnt = fopen("LPT1", "w");
            if (prnt == NULL) {
                    printf("Cannot open printer.\n");
            } else {
                    fprintf(prnt, "Hello, printing world!\n");
                    fclose(prnt);
            }
            return 0;
    }

    Some compilers define stdprn to be the printer output device. Look in stdio.h to see if it's defined, or simply try it.

    Note that this would not be standard C
