Use "PRN:" as the filename.  Try this:

#include <stdio.h>
#include <errno.h>

main()
{
    FILE *prntr;

    if ((prntr = fopen("PRN:", "w")) == NULL) {
        printf("Error %d! %s: %s\n", errno, "PRN:", strerror(errno));
        exit(1);
    }

  fprintf(prntr, "This appears on the printer,\nthen a page feed\f");
    fflush(prntr);
    fclose(prntr);
    exit(0);
}
