I've got what's probably a really easy question,
but I can't seem to find an answer in several different
books...can someone tell me how to send a stream to the
printer in borland c++ for windows?
 I've tried:
#define printer "LPT1"
  and
#define printer "PRN"
 even
#define printer "PRN:LPT1"
 then
ofstream outf;
outf.open(printer);  c++ seems to recognize PRN and LPT1 as valid
outf <<...           constants--no errors on run
                      but output is sent to screen(window).
the text says that stdio.h has a stream called stdprn
and i've tried to use
 fprintf(stdprn,"this is a test");
just to try that, and it goes to screen also.
The least capability I need is to be able to create a file then
print hard copy from within the program...I would like to be able
to send individual lines to printer for headers or summary that I
don't want in the actual file.
  Pardon me if I've missed something obvious.....
BTW this is windows 3.11 and borland c++4.52 (I also have turboc++3.1)

                thanks in advance

You don't say whether you are using an EasyWin application or not.  I assume you are.  I'm not certain, but I don't believe there is any easy way to do printer output.  The only way I've been able to do printer output under Windows is to use TPrinter and its associated classes.  The problem is that the printer is a spooled device, and Windows does *not* like you to take direct control of it.  Instead, you are expected to interact with the print manager.  I would have expected Borland to supply you with a "fake IO stream" under EasyWin that would take care of interacting with the print manager, but apparently they don't.
