    Question Port Scanning

    Hello there!
    I'm trying to find a c++ program that shows the signals or bin code that a printer port is sending to the printer from the computer in order to make an electronic application.
    Thanks in advance.

    Another one - boy, parallel port programming sure is popular at the moment
    Do a board search, this was discussed recently
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Okay, find out the address of the parallel port (no need for port scanning here--I'm thinking you didn't really mean "port scanning" as that either means scanning through all hardware ports or else scanning through all Internet connection ports (TCP/UDP/etc)) because the parallel port will only have a single hardware address.

    Also, read up on parallel port programming.

    ...and you'll probably want to do this in assembly language rather than in C++ since you are interfacing directly with the hardware.

    You other choice is to somehow find a device driver someone has made which does this and has a C API interface to it which you could then call in to to do your work.

    I am not a parallel port programmer, but if I were interested, those would be what I would do

    If you are programming under Linux, this is EXACTLY what you want
