I am attempting to use the Imagewriter I connected to the printer port as
a debugging tool in connection with a small application I am writing
using Lightspeed C Rev 2.11.  I have been successful in getting
output to the printer, but cannot get the paper to advance.  Here is the
relevant code fragment:

#include "stdio.h"
.
.
FILE *pfile;
.
.
pfile = fopen(".BOut", "a");
.
.
fprintf(pfile, "Hello, World\n");
fprintf(pfile, "This is the next line\n");
.
.
fclose(pfile);
.
.

The symptoms are that all the output is printed, but each succeeding
line of text overwrites the last one -- that is, the paper never advances.
The standard switch settings are used on the Imagewriter, and all standard
Mac applications print fine.  I have tried several workarounds:
	*  replacing the "\n" with "\012\015"
	*  using the escape code to force one or more line feeds
	*  turning on automatic line feed mode
Nothing works.   Any suggestions?
