A:Answer 1) Yes. This system is designed to use your existing network. It just adds wireless to it. So, if you are needing to print, wirelessly (laptop, phone, etc) to the printer wired to your network, it will work. 2) Depends on if I get your question: can you physically attach an external USB drive to these? No. Can you put an external USB drive, somewhere on your network and can you access the shared drive? Yes (it's best if on the wired network).
