	Depending on which version of C your using, the characters may be
being sent in "translated mode." The reason for this is the fact that
printers like \r\n for a newline, while the screen only likes \n. The
"translated mode" usually adds a \r for every \n going out, and strips all
of the \r's coming in.

	You can usually get around this translated mode with a flag in your
open command. I use Laser C, and to get around translated mode you have to
do something like:

FILE *open_file(fnme)
register char *fnme;
{
   FILE *file;
               /* The b flag sets it to "binary" or untranslated mode. */
   if ((*file = fopen(fnme, "br") == NULL)
      fprintf(stderr, "Error in opening file %s.", fnme);
   return(file);
}

for low-level access:

int open_file(fnme)
register char *fnme;
{
   int file;
         /* The O_BINARY flag sets it to "binary" or untranslated mode. */
   if ((file = open(fnme, O_RDONLY | O_BINARY)) == -1)
      fprintf(stderr, "Error in opening file %s.", fnme);
   return(file);
}

	Since you report the error even when using GEMDOS/BIOS/XBIOS routines
which have no such filtering, I think the problem must be in opening the file
to be output.
