Aha,  the line eater strikes again. Thanks for the hint Carolyn
I was uing Aztec C of the form:
	fh = fopen("prt:", "w");
	fputs("\x1b[2\"z", fh);

but I found out that if I use:
	fputs("some data for the line eater\x1b[2\"z", fh);

it worked!

I did some experimenting and found out that nulls didn't satisfy the old
line eaters (or should I say ESC eater) appetite but linefeeds did.
So be warned -- and Amiga printer driver guru's take note!

BTW my printer program now works and if enough people are interested
I can post it.  It prints multiple files in background with wildcard
selection and options for line numbers, headers, non-printing chars and
other features.  For example:
 pr -h *.c *.h -l manpage

will print all c and h files with headers and the manpage in letter quality mode
