    Cash Register and POS Printer Interaction

    Hi. I was wondering if anyone might have any links to information regarding software to hardware communication regarding cash registers and Point-of-Sale printers. If anyone could point me in the right direction, I'd greatly appreciate it. Thanks!

    Sounds like you want to brush up on embedded development or writting device driver's for an embedded OS.
    If you are looking for specs on a piece of hardware, you will need manufacturer/model #'s etc.

    Sounds like this might be from a job posting. If so, post the description/requierments here and I may be able to give you more insight into what the job entails.

    Yep, pretty much

    Yeah, this is from a job offer...unfortunately it's not an online posting, so I can't list the info about it. Most of the software stuff deals with DB's, which I can do. The main thing I need info on is the software/hardware interaction. Unfortunately, the cash register had no tags on it from what I could see, unless the monitor on top of it at the store was covering its info, which I will have to check. The printer is an Epson, model M129C. I looked at Epson's website briefly, but it's obviously a less recent model, and I didn't get a chance to look at the site long enough to find anything of use, though I'm def. planning to look again.

    Thanks so much for the reply!

    Your best bet is to turn over the devices and lookup the manufacturer and order the manuals and so forth...
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
