When and why you need to add a printer manually

Most printers connect automatically the first time you plug them in or join your home network. But sometimes that does not happen — your printer may be older, your computer may not recognize it, or you may be reconnecting after moving. When automatic detection fails, you add the printer manually by telling your operating system where to find it and what driver software to use.

The process differs between Windows and Mac, and the exact steps depend on whether your printer connects by USB cable or over WiFi. Both paths take about five to ten minutes once you have the printer's driver software, which is the small program that lets your computer talk to the printer.

Before you start, have your printer's model number ready — it is usually on a sticker on the back or bottom of the machine. You will also need to know whether it connects by USB or WiFi, and if WiFi, you should already have connected the printer to your home network using its own control panel or app.

Key Takeaways

  • read the printer driver from the manufacturer's website using your printer's exact model number before you start the manual setup.
  • On Windows, use Settings > Devices > Printers to add a printer, and Windows will search for it on USB or your network.
  • On Mac, use System Settings > Printers & Scanners and click the plus button to find and add the printer.
  • If your printer does not appear in the search, restart both the printer and your computer, then try again.
  • After adding the printer, print a test page from your computer's printer settings to confirm it is working.

read the driver before you begin

The driver is the software your computer needs to communicate with the printer. Without it, your computer can see the printer exists but cannot send print jobs to it. You can usually add the printer first and let Windows or Mac search for the driver automatically, but downloading it beforehand makes the process faster and more reliable.

Go to the manufacturer's website — common ones are HP, Canon, Epson, Brother, and Xerox. Find their support or downloads section, enter your printer's exact model number, and read the driver for your operating system (Windows or Mac) and version. Save it to your Downloads folder. If the website offers a choice between a basic driver and a full suite, the basic driver is enough for printing.

If you cannot find the model number, look on the printer itself: check the back panel, the front bezel, or inside the paper tray cover. It is usually a combination of letters and numbers like "HP LaserJet Pro M404n" or "Canon PIXMA TR8520".

Adding a printer on Windows

Open Settings by pressing the Windows key and typing "Settings", then click the Settings app. Go to Devices in the left menu, then select Printers & scanners. At the top of the right panel, click "Add device" or "Add a printer or scanner".

Windows will search for printers on your network and any connected by USB. If your printer appears in the list, click it and then click "Add device". Windows will install the driver automatically if it has one built in, or it will prompt you to install the driver you downloaded. If you downloaded the driver beforehand, click "The printer that I want isn't listed" at the bottom, then select "Add a printer using a TCP/IP address or hostname" or "Add a local printer", depending on your connection type.

For a USB printer that does not appear: make sure the USB cable is plugged into both the printer and your computer, then wait ten seconds and click "Refresh" or try the search again. For a WiFi printer that does not appear: confirm the printer is connected to your home network using the printer's own control panel, then restart the printer and try again.

Once the printer is added, Windows will show it in your Printers & scanners list. You can now print to it from any program by going to File > Print and selecting the printer name.

Adding a printer on Mac

Open System Settings by clicking the Apple menu in the top left corner and selecting System Settings. Click Printers & Scanners in the left sidebar. You will see a list of printers your Mac has already found. To add a new one, click the plus button at the bottom of the printer list.

A window will open showing available printers on your network and any connected by USB. Click the printer you want to add, then click "Add". If your printer does not appear, make sure it is turned on and connected to your home WiFi network (using the printer's own control panel), then click the dropdown menu at the top of the window and select "Default" or "Windows (SMB/CIFS)" to search different network types.

If the printer still does not appear, click "Select Software" at the bottom of the window. Mac will show you a list of printer drivers. Find your printer's manufacturer and model, select it, and click OK. Mac will then add the printer using that driver.

Once added, the printer will appear in your Printers & Scanners list. You can now print to it from any program by pressing Command+P, selecting the printer name from the dropdown, and clicking Print.

Troubleshooting when the printer does not appear

If your printer is not showing up in the search, the most common cause is that it is not actually connected to your network or powered on. Check that the printer is turned on — look for a power light on the front panel. If it is a WiFi printer, confirm it is connected to your home network by looking at the printer's own display screen or control panel. Most printers show a WiFi icon or network status on their screen.

Restart both the printer and your computer. Turn off the printer completely, wait ten seconds, and turn it back on. Then restart your computer. After both devices have restarted, try the search again. This clears temporary connection problems that prevent the devices from finding each other.

If the printer is USB-connected and still does not appear, try a different USB port on your computer. Some ports work better than others, and a faulty port can prevent detection. Also check that the USB cable is not damaged — look for kinks, cuts, or loose connectors.

If you have downloaded the driver and the printer still will not add, you can sometimes force the installation by running the driver file directly. On Windows, find the driver file in your Downloads folder, right-click it, and select "Run as administrator". On Mac, double-click the driver file and follow the installation prompts. After the driver installs, try adding the printer again.

Testing your printer after setup

Once the printer appears in your printer list, print a test page to confirm everything is working. On Windows, go to Settings > Devices > Printers & scanners, click your printer name, and click "Open queue". Then click "Printer" in the menu bar and select "Print Test Page". On Mac, go to System Settings > Printers & Scanners, select your printer, and click "Print Test Page".

The test page should print within a few seconds. If it does, your printer is ready to use. If nothing prints, check that the printer has paper and is not showing an error message on its own display. If the printer shows an error like "out of paper" or "toner low", fix that issue and try again.

If the test page still does not print, restart the printer and your computer once more, then try the test page again. If it fails a second time, the driver may not have installed correctly — uninstall the printer from your printer list, restart your computer, and try adding it again from the beginning.

Frequently Asked Questions

Do I need to install the driver before adding the printer?

No, but it helps. Windows and Mac can usually find a built-in driver automatically when you add the printer. Downloading the driver from the manufacturer beforehand makes the process faster and ensures you get the latest version, which may include features or fixes the built-in driver does not have.

What if my printer is very old and the manufacturer no longer has drivers?

Check the manufacturer's website one more time — they often keep drivers for older models in an archive section. If nothing is there, search online for "[printer model] driver" to see if another site hosts it. As a last resort, try adding the printer without a specific driver — Windows and Mac sometimes have generic drivers that work with older printers, though you may not be able to use all the printer's features.

Can I add the same printer to multiple computers?

Yes. Repeat the manual setup process on each computer. If the printer is on your WiFi network, each computer will find it and add it separately. If it is USB-connected, you will need to move the USB cable between computers or use a USB hub.

Why does my printer show up in the search but fail to add?

This usually means the driver did not install correctly. Restart your computer and try adding the printer again. If it fails a second time, uninstall the printer, read the driver directly from the manufacturer, run the driver installer, and then add the printer again.

What should I do if the printer adds but nothing prints?

First, print a test page from your printer settings — this tells you if the problem is with the printer itself or with a specific program. If the test page prints, the problem is with the program you are trying to print from. If the test page does not print, restart the printer and your computer, check for error messages on the printer's display, and try the test page again.
