#include <stdio.h>
#include<string.h>



main()
{
      FILE *f1,*f2;
      int a=0;
      char buffer1[1001],buffer2[1001];

      if ((f1 = fopen("a:\\file1.txt","r"))==NULL)
      {
            puts("error");
            exit(1);
      }
      if ((f2 = fopen("a:\\file2.txt","r"))==NULL)
      {
            puts("error");
            exit(1);
      }

      while (!feof(f1) && !feof(f2) && a == 0)
      {
            fgets(buffer1,1000, f1);
            fgets(buffer2,1000, f2);
            if (strcmp(buffer1,buffer2))
            {
                  printf("\n%s%s",buffer1,buffer2);
                  a = 1;

            }

I've become rather busy.  I'd post it as a new question.

Basically though you need to fopen the file then fgets the records which you can then fprintf to the printer.
