Please supply the details (how does it bomb? post everything that is
printed when it does).  Your program works for me, so I cannot
reproduce the problem.  (Of course, it doesn't really print anything
useful, since the effect of printing a binary value of 1 is dependent
on the printer model.)

You can also use the predefined stdprn stream (it's a FILE *, so use
it with the stdio functions like fwrite and fprintf).
