Quick fix
Connect the printer to your Wi-Fi from its control panel or the maker’s app, then add it on each computer. iPhones and many Android phones can print to compatible printers on the same network without extra apps.
Step by step
Connect the printer to Wi-Fi
Use the printer’s control panel (often a Wi-Fi or wireless setup option) or the manufacturer’s setup app. Choose your network and enter the password.
Give it a stable address (offices)
In an office, ask your IT team to reserve an IP address for the printer so it doesn’t “move” and go offline.
Add it on Windows
Settings > Bluetooth & devices > Printers & scanners > Add device.
Add it on a Mac
System Settings > Printers & Scanners, then add the printer.
Print from phones
On iPhone, compatible printers appear when you tap Share, then Print. Many Android phones have built-in printing or use the printer maker’s app or plug-in.
Print a test page
Print from each device once to confirm it works.
