To add Wi-Fi to a printer, you typically connect the printer directly to your Wi-Fi network using its built-in wireless setup options. For example, if your printer has a touchscreen, you can use the wireless setup wizard: turn on the printer, go to Setup > Network or Wireless Settings, select Wireless Setup Wizard, choose your Wi-Fi network, and enter the password to connect[1].
If your printer supports WPS (Wi-Fi Protected Setup), you can press the WPS button on your router, then select the Push Button Setup option on the printer and follow the onscreen instructions to pair it with your Wi-Fi network[1].
For printers without built-in Wi-Fi, you can connect the printer via USB or Ethernet to a Wi-Fi router that supports print server functionality, then install the printer’s USB print controller utility on your computer. This allows wireless printing through the router on your network[2].
After connecting the printer to Wi-Fi, add it to your computer by going to Settings > Bluetooth & devices > Printers & scanners on Windows, then selecting Add a printer and choosing your Wi-Fi printer from the list to install it and any required drivers[3].
