    Code:
    #include <stdio.h>
    
    int main ( int argc, char **argv ) {
    // use one of these to open a stream to the printer
    //    FILE *fp = stdprn;    // some environments define this at startup
    //    FILE *fp = fopen( "LPT1:", "w" );
    //    FILE *fp = fopen( "PRN:", "w" );
    
        // print to the printer
        // the \f is a formfeed - you might not see anything until you
        // use this to tell the printer the page is complete
        fprintf( fp, "hello world\n\f" );
        return 0;
    }
    Try one of these FILE* pointers
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
