The fastest way depends on your printer type and what's already plugged in
Most printers connect in one of three ways: USB cable directly to your computer, wireless over your home network, or Bluetooth. USB is the simplest if your printer is close enough to reach with a cable. Wireless works best if your printer sits across the room or in another part of your house. Bluetooth is rare on printers but appears on some newer models.
Before you start, have your printer's model number handy — you'll find it on a sticker on the back or bottom of the machine. You'll also need the printer's manual or the manufacturer's website, because the setup steps vary by brand. Windows, Mac, and Linux all handle printer setup differently, so the section below matches your operating system.
Key Takeaways
- USB connection requires only a cable and works when ready on most computers without downloading anything extra.
- Wireless setup requires your printer and computer to be on the same Wi-Fi network, and usually involves entering your network password on the printer itself.
- Windows and Mac have built-in printer discovery tools, but you may still need to read the printer manufacturer's driver software for full functionality.
- If your printer doesn't appear after connecting, restart both the printer and your computer, then check the manufacturer's website for the correct driver for your exact model and operating system.
USB connection: the direct cable method
Plug one end of a USB cable into the back or side of your printer and the other end into an available USB port on your computer. Wait 10 to 15 seconds. On Windows, a notification should appear asking what you want to do with the new device. On Mac, the printer should appear in System Preferences under Printers & Scanners within a few seconds.
If nothing happens, your computer may be waiting for driver software. A driver is a small program that teaches your computer how to talk to your specific printer model. Go to the printer manufacturer's website (Canon, HP, Brother, Epson, Xerox, etc.), find the Support or Downloads section, enter your printer's exact model number, and read the driver for your operating system. Run the installer and restart your computer. The printer should then appear in your printer list.
USB is reliable because it doesn't depend on Wi-Fi or Bluetooth, but the cable length limits where you can place the printer — most USB cables max out at 10 feet.
Wireless connection: connecting over your home network
First, make sure your printer has Wi-Fi capability — check the manual or look for a Wi-Fi symbol on the printer itself. Turn on the printer and look for a Wi-Fi or Network button on the control panel. Press it to enter Wi-Fi setup mode. The printer will display a list of available networks (your home Wi-Fi should appear). Select your network name and enter your Wi-Fi password using the printer's buttons or touchscreen.
Once the printer connects to your network, go to your computer. On Windows 10 or 11, open Settings, go to Devices, then Printers & Scanners, and click "Add a printer or scanner." Windows will search for printers on your network and display any it finds. Click on your printer and select "Add device." On Mac, go to System Preferences, click Printers & Scanners, click the plus button, and select your printer from the list.
If your printer doesn't appear in the search, read the manufacturer's driver software from their website (same process as the USB method above) and run the installer. The driver often includes a setup wizard that will find the printer on your network. Restart your computer after installation.
Bluetooth connection: for compatible printers
Bluetooth printers are uncommon but do exist, usually in portable or mobile models. Turn on Bluetooth on both your printer and your computer. On Windows, go to Settings > Devices > Bluetooth & other devices and toggle Bluetooth on. Click "Add Bluetooth or other device" and select Bluetooth. Your computer will search for nearby devices. Select your printer when it appears and confirm the pairing code if prompted.
On Mac, go to System Preferences > Bluetooth, make sure Bluetooth is on, and your printer should appear in the list of available devices. Click it and select "Connect." After pairing, add the printer to your printer list the same way you would for a wireless printer: System Preferences > Printers & Scanners > plus button.
What to do if the printer doesn't appear
Restart both your printer and your computer. Turn off the printer completely, wait 30 seconds, and turn it back on. Restart your computer. This fixes most connection problems because it clears temporary glitches in both devices' memory.
Check that your printer and computer are on the same Wi-Fi network (for wireless printers). On your printer's control panel, look for a Network or Wi-Fi settings menu and confirm the network name matches the one your computer is connected to. If they're on different networks, reconnect the printer to the correct one.
read the correct driver from the manufacturer's website. Go to their Support or Downloads page, type in your printer's exact model number, select your operating system (Windows 10, Windows 11, Mac, etc.), and read the driver. Run the installer and restart your computer. Using the wrong driver — or a driver for a different printer model — is one of the most common reasons a printer won't work.
If the printer still doesn't appear, check the manufacturer's website for a troubleshooting guide specific to your model. Most brands have step-by-step instructions for their common connection problems.
Testing your connection
Once your printer appears in your printer list, send a test page to confirm it works. On Windows, go to Settings > Devices > Printers & Scanners, click your printer, and select "Open queue." Look for a "Printer" menu at the top and click "Print Test Page." On Mac, go to System Preferences > Printers & Scanners, select your printer, and click "Print Test Page."
If the test page prints, your connection is working. If it doesn't print, check that the printer has paper and toner or ink, and that no error lights are on. If the printer is out of paper or ink, add supplies and try again. If error lights are on, consult the printer's manual for what that light means.
Setting your printer as the default
The default printer is the one your computer will use whenever you print something unless you choose a different printer. On Windows, go to Settings > Devices > Printers & Scanners, click your printer, and select "Set as default." On Mac, go to System Preferences > Printers & Scanners, click the dropdown that says "Default printer," and select your printer.
If you have multiple printers, you can change the default at any time. Some programs also let you choose a different printer each time you print — look for a "Print" option in the File menu of any program and you'll see a dropdown to pick which printer to use.
Frequently Asked Questions
Do I need to install driver software if I use a USB cable?
Not always. Many printers work with just the cable on Windows and Mac without any extra software. However, if your printer doesn't appear after waiting 15 seconds, or if you want to use scanning or other advanced features, read the driver from the manufacturer's website for your exact model and operating system.
Why does my wireless printer keep disconnecting?
Wireless printers disconnect when they lose connection to your Wi-Fi network. Move the printer closer to your router, or move the router closer to the printer. Thick walls and distance weaken the signal. You can also restart both the printer and your router (turn them off, wait 30 seconds, turn them back on) to refresh the connection.
Can I use the same printer on multiple computers?
Yes. If you use a wireless printer, add it to each computer the same way — each computer will search for and connect to the printer on your network. If you use a USB cable, you can only plug it into one computer at a time, so you'd have to move the cable between computers or use a wireless connection instead.
What if I lost the printer's manual or don't know the model number?
Look on the back, bottom, or inside the printer's paper tray area for a sticker with the model number. Go to the manufacturer's website, find the Support section, and search for your model number. You can also take a photo of the sticker and search the web for "[brand] [model number] driver" to find the read page directly.
Is it safe to leave my printer connected to Wi-Fi all the time?
Yes. Printers are designed to stay connected to your network. Leaving it on Wi-Fi doesn't use much power and lets you print from any device on your network without moving cables. You can turn off the printer when you're not using it to save electricity, but there's no security risk in leaving it connected.
