You coult just attach 'lpt1:' to your 'cout' object, e.g.

int fd = _open ( "lpt1:", _O_TEXT | _O_WRONLY);
cout.attach ( fd);

cout << setiosflags(ios::left)<<setw(5)<<AccountNumber<< setw(28)<<name;
cout << setw(17)<<Curr<<setw(12)<<calcu<<setw(8)<<code;

Or, leave cout alone and use

ofstream prn;

int fd = _open ( "lpt1:", _O_TEXT | _O_WRONLY);
prn.attach ( fd);

prn << setiosflags(ios::left)<<setw(5)<<AccountNumber<< setw(28)<<name;
prn << setw(17)<<Curr<<setw(12)<<calcu<<setw(8)<<code;

Oh, and don't forget to

_close( fd);

when it is no longer needed. Speaking of that, you need to add

#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <io.h>
