How to Connect a Printer to a Laptop or Computer With USB

1What this lesson covers

This lesson shows you how to connect printer to laptop or desktop computers with a USB cable. USB is the simplest connection: no network settings and no passwords. It suits a student’s desk, a home office with one computer, or any time Wi-Fi is unreliable. You’ll pick the right cable, plug in in the right order, and confirm Windows or macOS has installed the printer.

2Before you start

USB connects the printer to one computer at a time. If several people need to print, Wi-Fi or Ethernet is usually better; see how to connect a printer to Wi-Fi.

Check the port on the back of the printer. Most use a squarish USB-B socket, so the usual cable is “USB-A to USB-B” (flat plug for the computer, square plug for the printer). Laptops with only USB-C ports need a “USB-C to USB-B” cable or a USB-C adapter. Some newer printers use a different socket; the manual’s specifications page names the cable.

Chromebooks and tablets handle USB printers differently, and not every model supports them. This lesson covers Windows and macOS; for other devices, check the printer manufacturer’s support page for your model.

3Connect and install on Windows

1. Switch on the printer and wait until it’s ready.
2. Plug the cable into the printer, then into the computer. Use a port directly on the computer rather than a hub or keyboard port. You should see: a notification that Windows is setting up a device.
3. Wait for the driver. Windows looks for a matching driver, using Windows Update if needed. This can take a few minutes on the first connection.
4. Open Printers & scanners to check. In Windows 11 go to Settings, Bluetooth & devices, Printers & scanners; in Windows 10, Settings, Devices, Printers & scanners. You should see: your printer in the list.
5. Add it manually if it’s missing. Select Add device (Windows 11) or Add a printer or scanner (Windows 10) and choose your printer. Full details are in add a printer to Windows.

4Connect and install on a Mac

1. Install macOS updates first, so the latest printer software from Apple is available.
2. Switch on the printer and connect the cable, using an adapter if your Mac needs one.
3. Wait a moment. macOS often adds a USB printer by itself. If it asks to download software from Apple, allow it.
4. Check Printers & Scanners. Choose the Apple menu, System Settings, Printers & Scanners (or System Preferences on older macOS). You should see: your printer listed. If not, click Add Printer, Scanner or Fax, select it and click Add.

5Check that it worked

Print a test page. On Windows, open Printers & scanners, select the printer and choose Print test page. On a Mac, print a short document from any app using File, Print. You should see: the page print within a minute. Unplug and reconnect the cable once; the printer should come back on its own without reinstalling.

6Troubleshooting

• Nothing happens when you plug in. Try another USB port and another cable if you have one. Cables can fail without any visible damage.
• Windows shows “Unknown USB device”. Unplug, restart the computer, and connect again directly to the computer. If it persists, install the driver from the manufacturer’s site using how to find and install the right printer driver.
• It prints, then stops. Check that the cable isn’t loose at either end and isn’t stretched across a walkway.
• Adapter doesn’t work. Some cheap adapters are charge-only or unreliable. Try a different adapter or a direct USB-C to USB-B cable.
• The computer went to sleep and the printer vanished. Wake the computer fully and wait a few seconds; USB devices reconnect when it resumes.
• You see two copies of the printer. One may be from an earlier Wi-Fi setup. Print from the one marked as USB, and remove the other if you don’t use it.

7When to get more help

If the computer never detects the printer with different cables and ports, the printer’s USB port looks damaged, or the printer shows a hardware error, contact the manufacturer’s support for your model. A loose or broken port is a repair job; don’t open the printer to look at it.

8FAQ

Does the printer need its own power if it’s on USB?

Yes. USB carries data between the computer and printer, but the printer still needs its own power cable plugged into an outlet and switched on.

Can I use USB and Wi-Fi at the same time?

Many printers allow both: one computer by USB and other devices over Wi-Fi. Your computer may list them as two printers. Check your manual for your model’s options.

Can I share a USB printer with another computer?

Windows and macOS have printer sharing features, but the computer with the cable must stay switched on. For regular sharing, connecting the printer to the network is simpler.

Is a USB printer cable the same as a phone charging cable?

No. Phone cables have different plugs at the printer end. Look for a cable labeled USB-A to USB-B (or USB-C to USB-B) printer cable.

Do I need to install software from a disc?

No. Windows and macOS find drivers for most USB printers automatically, and anything else comes from the manufacturer’s official website.
