[erlang-questions] Controlling LPT port from Erlang

[Dmitry Kolesnikov]

Hello,

I am not aware of any LPT support or existed libraries at Erlang.
The solution would be OS dependent. BTW, what is OS you are doing development? 

All-in-all, I am afraid that you have to procedure with NIF development.
Please see the following link about NIF development:

http://www.erlang.org/doc/man/erl_nif.html
http://www.erlang.org/doc/tutorial/nif.html

If you happened to do Linux then I would recommend to look into following project.
I use direct memory I/O (no linux kernel drivers are needed)

Best Regards, 
Dmitry
