To hook up a wireless printer, first turn on both your printer and Wi-Fi router. Then, use the printer’s control panel or setup menu to find the wireless settings or Wi-Fi setup wizard. Select your Wi-Fi network SSID from the list and enter the network password when prompted. The printer will connect to your Wi-Fi network, indicated usually by a blue Wi-Fi light or confirmation message[1][2][3].

For example, on many printers, you can press the Wi-Fi button or use a touchscreen to open the wireless setup wizard, select your network, and input the Wi-Fi password to connect[2]. Some printers also support WPS (Wi-Fi Protected Setup), where you press the WPS button on your router and then press the Wi-Fi button on the printer for about five seconds to connect automatically[1].

After connecting the printer to Wi-Fi, install the printer drivers on your computer or mobile device. On Windows, go to Settings > Bluetooth & devices > Printers & scanners, and add the printer if it’s not already listed[4]. On Mac, use the Printer Setting Tool or Wireless Device Setup Wizard that usually comes with the printer’s driver package[1].

In summary:
1. Turn on printer and router.
2. Use printer’s Wi-Fi setup (via control panel or app) to select your Wi-Fi network and enter password.
3. Wait for connection confirmation.
4. Install printer drivers on your computer/mobile and add the printer as a wireless device.

These steps are generally applicable to many brands like Brother, HP, and others, though exact menu names may vary[1][2][3][4].
