It sure can! You can connect to your laptop to the printer with any USB Type-A male to Type-B male USB cable. The socket for the cable is on the back of the printer
#2 What does the printer scan to if not scanning to email?
With the option “scan for print”, the printer sends the file to a folder in the computer.
#3 Can this scanner scan documents into my computers?
It can print both sides but you have to flip the paper. If you're printing several sheets then you print all the evens and then flip it and it will print all the odds on the opposite side.
