I use Olive Office, which works very well for Word docs. It has a usb port, but I don't know if it can hook up to a printer. I'm using it for classes a bit as well, but for heavy typing I would suggest getting an attachable keyboard.
Yeah. But it costs A LOT! Above 10$ for office apps which are very good in processing. But Coby sucks in power to support them. There's a USB port through which you can connect to a printer. But I don't know if any app supports it. For students its a good reading tablet, but it gets stuck if you try to browse heavy websites or even if you try googling for something. Its better to save some money and go for any tablet above 200$
