How do I make sure my printer and computer are on the same network?

My printer shows offline.  All the quick help steps say to make sure my printer and computer are on the same network.  How do I do this?

The printer needs to be on the same subnet as the rest of your devices unless the printer is set for Wi-Fi direct.
Check the IP4 address of your computer and then get a network printout and see if both the printer and the computer are on the same network.

Using the windows command prompt, copy and paste the following into the CMD window

ipconfig | find /i "ipv4"

should look someting like the below

Get a printer network report. The PINs and Passwords should show up. Here is the important stuff from a typical printer report. The password shown in WiFi can be the printers PIN or the modem's password depending on how you connected to the modem. The printer can have two bands but the only one that is connected will show up.

LAN	STATUS	IP address	SSID	Password
WiFi	enabled	192.168.1.15	ATT-ARRIS-2 .4	GuessAgain
WiFi-direct	enabled	192.168.23.1	DIRECT-WHATEVER	BadGuess
Wired	disabled
USB	disabled

Note that the printer and the computer are both 192.168.1
This means they are on the same subnet.

This can get complicated if you have a mesh network or a lot of WiFi boosters.  

Please provide the Model name of the printer for better assistance.

I presume, since you are asking this, you are using WiFi, correct?  Is your PC also using WiFi?  Or is it connected to a WiFi router using an ethernet cable?
