I'm not quite sure but maybe you can try the following:

std::string str = "hello";
std:fstream printer("LPT1");
printer << str;

C++ doesn't not define any interaction with hardware it is all
abstracted through streams.

For an answer that works for NT you need to ask in a Windows programming
group, because this is really a Windows programming question not a C++
question. Try for instance.
