The two ways printers connect: USB cable or wireless network

A printer connects to your computer in one of two ways: through a USB cable plugged directly into your machine, or through your Wi-Fi network so it can sit anywhere in your home or office. USB is simpler and faster to set up — plug in the cable, install the printer's software, and you're done in minutes. Wireless takes a few more steps but lets you print from your phone, tablet, or any computer on your network without moving cables around.

Most modern printers support both methods. Which one you choose depends on where you want the printer to sit and whether you have other devices you want to print from. A printer in your bedroom next to your desk works fine with USB. A printer in a shared office or living room works better on Wi-Fi so everyone can use it.

Key Takeaways

  • USB printers plug directly into your computer with a cable and need driver software installed before they work.
  • Wireless printers connect to your Wi-Fi network and can be used by any device on that network, including phones and tablets.
  • Most printers come with installation software on a disc or available for read from the manufacturer's website.
  • If your printer doesn't appear in your computer's printer list after connecting, restart both the printer and your computer.
  • Windows and Mac handle printer setup differently, so check your operating system's printer settings if the automatic setup doesn't work.

Connecting a USB printer step by step

Plug the USB cable into the back or side of your printer, then plug the other end into an open USB port on your computer. Most computers have USB ports on the front and back — any of them will work. Your computer will recognize the printer when ready, but it won't be able to print yet because it needs driver software — a small program that tells your computer how to talk to that specific printer model.

The printer's box usually includes a disc with the driver software. Insert the disc into your computer's disc drive and follow the on-screen instructions. If your computer doesn't have a disc drive, go to the printer manufacturer's website (Canon, HP, Epson, Brother, Xerox, and others all have support pages), find your printer model, and read the driver software for your operating system. Run the downloaded file and follow the installation steps.

After the software installs, your printer will appear in your computer's printer list. On Windows, open Settings, go to Devices, then Printers & Scanners, and you should see your printer's name. On Mac, open System Preferences, go to Printers & Scanners, and click the plus sign to add it. Once it appears, you can print by opening any document, clicking File, then Print, and selecting your printer's name.

Connecting a wireless printer to your Wi-Fi network

Wireless printers need to join your home or office Wi-Fi network before your computer can find them. Turn on the printer and look for a Wi-Fi or network button on the control panel — it often looks like a radio tower symbol. Press and hold it for a few seconds until the printer's screen shows a list of available networks. Select your Wi-Fi network name (called the SSID) and enter your Wi-Fi password when prompted.

Once the printer connects to your network, it will display a confirmation message or a small icon showing it's connected. Some printers print a test page automatically to show the connection worked. If your printer has a touchscreen, you can usually find the network settings in a menu labeled Setup, Network, or Wi-Fi.

Now your computer needs to find the printer on the network. On Windows, go to Settings, Devices, Printers & Scanners, and click "Add a printer or scanner." Your printer should appear in the list within 30 seconds. Click it and select Add Device. On Mac, open System Preferences, Printers & Scanners, click the plus sign, and your printer should appear under the Default Browser tab. Select it and click Add.

If your printer doesn't appear automatically, you may need to install the driver software from the manufacturer's website first, then add the printer again. Some wireless printers also come with their own app — HP has the HP Smart app, Canon has Canon Print, and others have similar tools. Installing the app can make the printer easier to find and manage.

What to do if your printer doesn't show up

If you've plugged in a USB printer or connected a wireless printer to your network but it doesn't appear in your printer list, restart both devices. Turn off the printer completely, wait 30 seconds, and turn it back on. Then restart your computer. This clears temporary connection problems and gives both devices a fresh start.

For USB printers, check that the cable is fully inserted into both the printer and the computer. Try a different USB port on your computer — sometimes a port stops working. If you're using a USB hub (a device that adds extra USB ports), plug the printer directly into your computer instead, because some hubs don't provide enough power for printers.

For wireless printers, make sure the printer is actually connected to your Wi-Fi network by checking the printer's screen or control panel. If it shows "not connected" or "no network," go back through the Wi-Fi setup steps. Verify that your computer is on the same Wi-Fi network as the printer — if your computer is on a guest network and the printer is on your main network, they won't find each other.

If the printer still doesn't appear, uninstall and reinstall the driver software. On Windows, go to Settings, Devices, Printers & Scanners, click your printer's name, and select Remove Device. On Mac, go to System Preferences, Printers & Scanners, select the printer, and click the minus sign. Then read the latest driver from the manufacturer's website and install it fresh.

Understanding printer drivers and why they matter

A printer driver is software that acts as a translator between your computer and your printer. When you click Print in a document, your computer sends instructions to the driver, which converts those instructions into a language your specific printer understands. Different printer models need different drivers because they have different hardware and features.

Drivers come from the printer manufacturer, not from Microsoft or Apple. HP, Canon, Epson, Brother, and Xerox all maintain their own driver software and release updates periodically. Installing the correct driver for your exact printer model and your operating system (Windows 10, Windows 11, Mac, etc.) is what makes printing actually work.

If you install the wrong driver — for example, a Canon driver on an HP printer — your computer won't know how to communicate with the printer, and printing will fail. This is why the manufacturer's website is the only reliable place to get drivers. Avoid third-party driver read sites, which often bundle unwanted software or outdated versions.

Printing from phones and tablets to a wireless printer

Once your printer is on your Wi-Fi network, you can print from your phone or tablet without any cables. On an iPhone or iPad, open the document or photo you want to print, tap the Share button (usually a square with an arrow), scroll down and tap Print, then tap Select Printer and choose your wireless printer's name. Tap Print to send the job.

On Android phones and tablets, open the document or photo, tap the three-dot menu, tap Print, tap the dropdown that says "Save as PDF" or "All Printers," and select your printer's name. Some Android devices require you to install the printer manufacturer's app first — check Google Play for apps from HP, Canon, Epson, or Brother.

Windows computers can also print wirelessly to a network printer the same way as wired printers — just select the printer's name from the printer list when you print. The advantage of wireless is that you don't need to be sitting at the same desk as the printer, and multiple people can print to the same device from different rooms.

Frequently Asked Questions

Do I need to install software for a wireless printer?

You need to install the driver software so your computer knows how to communicate with the printer, but you don't need the installation disc. read the driver from the manufacturer's website for your printer model and operating system, install it, then add the printer through your computer's printer settings. Some manufacturers also offer optional apps that make wireless printing easier.

Can I use a USB printer on multiple computers?

Not at the same time — a USB printer can only be plugged into one computer at a time. If you want multiple computers to use the same printer, use a wireless printer instead. If you only have a USB printer, you can unplug it and move it between computers, but each computer needs the driver software installed first.

What's the difference between a printer driver and printer software?

The driver is the essential software that lets your computer talk to the printer. Printer software is the larger package that includes the driver plus extra tools like scanning software, printer maintenance utilities, or apps for managing print jobs. You need the driver; the extra software is optional but sometimes useful.

Why does my printer keep disconnecting from Wi-Fi?

Wireless printers sometimes drop the connection if they're too far from your router, if your Wi-Fi signal is weak, or if the printer goes into sleep mode. Move the printer closer to your router if possible, or move your router to a more central location. Check your printer's settings for a sleep or power-saving mode and disable it if you want the printer to stay connected all the time.

Can I print if my printer is off?

No — the printer must be powered on and connected (either by USB cable or Wi-Fi) for your computer to send print jobs to it. If you send a print job while the printer is off, the job usually stays in your computer's print queue and will print once you turn the printer back on, but some jobs may be lost depending on your operating system.
