What to Do If Your Mac Doesn’t Recognize a Printer or Scanner

Trying to print or scan something urgent, only to find your Mac doesn’t recognize the device? Whether it’s a USB or wireless printer/scanner, this is a common issue—and luckily, it often has simple solutions.

🔍 Start With the Basics

Before diving into complex fixes, make sure:

• Cables and connections are working: If USB, check the cord and try different ports or cables.

• The device is turned on: Many printers go into sleep mode. Ensure it’s powered up and ready.

• Wi-Fi/network is set properly: For wireless devices, confirm they’re connected to the same network as your Mac. Restarting your router and the device may help.

⚙️ Configure the Device Correctly

• System Settings > Printers & Scanners:

  Open this panel to check if your Mac detects the device. If not, click the "+" button to add it manually.

• Download necessary drivers:

  Some printers require additional software. Visit the manufacturer’s website for macOS-compatible drivers.

• Reset the printing system:

  In the “Printers & Scanners” menu, right-click and choose “Reset printing system.” This clears previous settings and lets you start fresh.

🛠️ Additional Fixes to Try

• Update macOS: Outdated versions may lack compatibility with newer printer models.

• Restart both devices: A simple reboot can restore lost connections.

• Try AirPrint: Many modern printers work with AirPrint, which eliminates the need for drivers.

• Check permissions and firewall settings: Security software might be blocking the connection.

🧠 When to Get Help

If none of these steps work, it's best to consult a tech expert. At iProX, we can help you identify whether the issue is software-related, a hardware malfunction, or a compatibility problem.

Conclusion

A printer or scanner that doesn’t show up on your Mac isn’t always broken. Most of the time, a few tweaks in settings or an update will bring everything back to normal.
