A:AnswerNo usb included, but you don't need it. It has wireless connection, and it actually works very well.
I have this connected to my android phone, a tablet, a chrome book, and a regular hp laptop.
All wireless and functions perfectly, very clean set-up. Just follow instructions, downloading the brother I-print app

A:AnswerSingle sheet, this printer, although very good, is not really designed for major copy jobs. Only one at a time.
Copying several page's is fine but larger job would be a pain. But for printing and scanning it's great.
A:AnswerThis printer can only print black & white. It does not use ink cartridges, it uses toner only. And as far as I know you can only purchase toners in black.
A:AnswerIt will work with any standard wifi, on 2.4ghz (not 5). So, it will work with any router. There is also an option or USB or ethernet. So if your Arris modem is also a router, you can connect other computers to this printer. If your Arris modem is only a modem, I don't see the purpose but yes, you could connect the two via ethernet cable to give this printer internet access (but then not local access to other computers).
