There are several ways to connect a printer to your computer. Which option you choose depends on the device itself, and whether you're at home or at the office.
Always consult the information that came with your model for specific instructions.
The most common way to install a printer is to connect it directly to your computer. This is known as a local printer.
If your printer is a universal serial bus (USB) model, Windows should automatically detect it and begin installation when you plug it in.
If you're installing a wireless printer that connects to your computer over a wireless network (Wi‑Fi), you can use the Add a device wizard to install the printer. For instructions, see Connect to Bluetooth and other wireless or network devices.
If it's an older model that connects using the serial or parallel port, you might have to install it manually.
