Computer Ports

I often get emails asking me how to connect / format various printers, scanners, pole displays, etc. to their computer to use with my POS software. To which I respond, "What port does your thingie plug into, parallel, serial, USB, or other.?"

To which a common response is, "How am I supposed to know?

Fair enough.
