## **1. Common Causes of ‘Printer Not Detected’ on Mac**

Before diving into fixes, it’s essential to understand the potential reasons your Mac might not recognize your printer. The issue could be caused by:

### **1.1. Outdated or Corrupted Printer Drivers**

Drivers act as the bridge between the Mac operating system and the printer. If they're outdated or incompatible, the printer may not be recognized.

### **1.2. Faulty USB Cable or Port**

When using a wired connection, a damaged USB cable or faulty USB port can prevent your Mac from detecting the printer.

### **1.3. Network Issues**

For wireless printers, weak Wi-Fi signals or incorrect network settings can block communication between your Mac and the printer.

### **1.4. macOS Updates**

Sometimes, a recent macOS update might not support your printer until a driver or firmware update is applied.

### **1.5. Printer Compatibility**

Not all printers are compatible with every macOS version, especially older models.

## **2. Preliminary Checks**

Before attempting more advanced solutions, ensure the following:

* Your printer is turned **on** and has **paper**, **ink/toner**, and no **error indicators**.
* The **Wi-Fi** or **Bluetooth** (if applicable) is turned on.
* You're using the **latest macOS version**.
* Your printer is **compatible** with your current macOS.

## **3. Troubleshooting Wired Printers**

Wired printers are generally more straightforward to set up. If your Mac doesn't detect a USB printer, follow these steps:

### **3.1. Check the USB Connection**

* Ensure the USB cable is **securely connected** to both your Mac and the printer.
* Try using a **different USB port** on your Mac.
* If available, try a **different USB cable** to rule out cable damage.
* If you're using a **USB-C to USB-A adapter**, ensure it’s Apple-certified.

### **3.2. Restart Devices**

* Power off the printer and Mac.
* Disconnect the USB cable.
* Restart both devices.
* Reconnect the USB and try again.

### **3.3. Check for Printer in System Settings**

1. Go to **System Settings** > **Printers & Scanners**.
2. If your printer is listed, remove it and re-add it:

* Select the printer, click **Remove Printer (-)**.
* Click **Add Printer (+)** and see if it's detected now.

## **4. Troubleshooting Wireless Printers**

Wireless printers can be finicky due to Wi-Fi connectivity, router issues, or misconfiguration.

### **4.1. Reconnect the Printer to Wi-Fi**

* Use the printer’s control panel to **forget and reconnect** to the Wi-Fi network.
* Make sure the printer and Mac are connected to the **same network**.
* Avoid public or guest Wi-Fi networks that block communication between devices.

### **4.2. Restart Network Equipment**

* Power off the **printer**, **Mac**, **router**, and **modem**.
* Wait 60 seconds.
* Turn everything back on starting with the modem, then the router, then the printer, and finally your Mac.

### **4.3. Re-Add the Printer**

1. Go to **System Settings** > **Printers & Scanners**.
2. Click the **+** button.
3. Select the printer from the list (should appear with “Bonjour” or “AirPrint”).
4. Click **Add**.

### **4.4. Use Printer IP Address**

If your printer is not automatically showing:

1. Find your printer's **IP address** from its control panel or settings.
2. On your Mac, go to **System Settings** > **Printers & Scanners** > **+**.
3. Click the **IP** tab.
4. Enter the IP address, select protocol (usually AirPrint), and add the printer manually.

## **5. Update or Reinstall Printer Drivers**

### **5.1. Update macOS**

Sometimes macOS includes updated printer drivers:

* Go to **System Settings** > **General** > **Software Update**.
* Install any available updates.

### **5.2. Download Drivers from Manufacturer’s Website**

If your printer requires specific drivers:

* Visit your printer manufacturer’s website (e.g., HP, Canon, Epson, Brother).
* Search for your printer model.
* Download and install the **latest macOS drivers**.

### **5.3. Reset Printing System**

This clears all printer settings and drivers:

1. Go to **System Settings** > **Printers & Scanners**.
2. Right-click in the Printers list or hold Control + Click.
3. Choose **Reset Printing System**.
4. Re-add your printer after the reset.

## **6. Fixing AirPrint Detection Issues**

**AirPrint** is Apple’s built-in solution to print wirelessly without installing drivers.

### **6.1. Ensure AirPrint Support**

* Check if your printer supports AirPrint. Visit [Apple’s AirPrint Support List](https://support.apple.com/en-us/HT201311).
* If not supported, install drivers manually.

### **6.2. Check Firewall and Security Software**

Sometimes, firewalls block AirPrint connections.

* Go to **System Settings** > **Network** > **Firewall**.
* Temporarily disable the firewall to test detection.
* Re-enable after testing and allow printer-related traffic if needed.

## **7. Bluetooth Printer Not Detected**

Bluetooth printers are less common but still used.

### **7.1. Enable Bluetooth**

* On your Mac, go to **System Settings** > **Bluetooth** and ensure it’s on.
* Put your printer in Bluetooth discovery mode.

### **7.2. Pair the Printer**

* In the Bluetooth settings, wait for your printer to appear.
* Click **Connect**.
* If prompted, enter a pairing code (often 0000 or 1234).

## **8. Printer Detection After macOS Update**

macOS updates occasionally cause printer compatibility issues.

### **8.1. Reinstall Printer Software**

* Uninstall old drivers.
* Reinstall updated drivers compatible with the new macOS version.

### **8.2. Contact the Manufacturer**

If you can’t find compatible drivers, visit the printer manufacturer’s support or forums. Some may offer **beta drivers** or workarounds.

## **9. Additional Tools and Commands**

### **9.1. Use Terminal to Reset Printing System**

Advanced users can use Terminal:

sudo rm -r /Library/Printers/
sudo rm -r /System/Library/Extensions/IOPrinterFamily.kext

**Note:** Only use this if you are experienced or with guidance from support.

### **9.2. Check CUPS Web Interface**

CUPS (Common Unix Printing System) helps manage printers:

* Open Safari or any browser.
* Type `http://localhost:631` and press Enter.
* Enable it by typing in Terminal:

cupsctl WebInterface=yes

Use the CUPS interface to manage, remove, or restart printers.
