How to connect printer to wifi first step is to find the printer's IP address. You can do this by looking at the control panel on your computer or by contacting your network administrator. Next, you'll need to login to your router and assign an IP address for your printer. This can be done by opening the router configuration page and adding a new device with an IP address, Subnet mask and Gateway. Finally, you'll need to connect the printer wirelessly. To do this, turn on WiFi on the printer and then select "Wireless Setup" from its menu options.
