Adding a printer to a computer usually involves connecting it via USB or over a network. If it's a wireless printer, make sure both your printer and computer are on the same network. You can then go to "Devices and Printers" in your computer's settings to add a printer. It often helps to have the printer's user manual handy. Have you had any trouble with this process so far? Or is there a specific type of printer you're working with? I'm here to help!
