Watch the following video on how to setup the printer.

Troubleshooting
If you still failed to print even after you've followed the steps in the video above, try checking these:
1.) Your Device and Printer are in the same network. (Connected to the same router)
2.) Your Device and Printer are in the same subnet. (You need to acquire your printer IP address first, shown in the video above)
To check on this you need to know the IP of your device:

Once you get your device IP, try comparing it with your printer IP to see if they are in the same subnet.
Example 1 (same subnet)
Device IP: 192.168.0.100
Printer IP: 192.168.0.20
Example 2 (different subnet)
Device IP: 192.168.0.100
Printer IP: 202.188.50.20
