Setting up wireless printing in the Apple ecosystem is traditionally considered one of the simplest procedures in the world of computing. However, even in a perfectly streamlined macOS system, situations sometimes arise where automatic device detection fails on the first try. Users encounter this when changing routers, updating the operating system, or using printer models that don't support the native protocol. AirPrint.
In this article, we will examine in detail all possible scenarios for connecting a printing device to iMacWe'll cover both standard methods using system settings and manual driver installation for older or specific models. Understanding how network protocols work will help you avoid common mistakes and save time.
Before you begin software configuration, it is critical to ensure that your hardware is physically ready to work wirelessly. Both the iMac and the printer must be on the same Wi-Fi network, otherwise discovery will not be possible. You should not rely on automatic settings if the underlying network infrastructure is not configured correctly.
Preparing equipment and checking the network
The first and most important step, often overlooked, is physically preparing the printer. Make sure the printer is turned on, there's paper in the tray, and the cartridges are installed correctly. If the device was previously used with another computer or connected via USB, it's recommended to reset the printer's network settings to factory defaults to avoid IP address conflicts.
Check the status of your Wi-Fi connection on the iMacSometimes the system may show a network connection, but there's no actual internet or local resource access. Open System Preferences and go to the Network section. Make sure the connection status is active and there are no warning signs.
⚠️ Attention: If your router supports dual-band, make sure both devices are connected to the same frequency (either both to 2.4 GHz or both to 5 GHz). Some older printer models don't see 5 GHz networks or won't work properly if the computer is on a different subnet.
For modern models with a touchscreen, the process is simplified to simply selecting your network from the list on the printer display and entering the password. For devices without a screen, the following method is often used: WPSFind the WPS button on your router, press it, and then press the same button on your printer (or the button combination described in the instructions). The Wi-Fi indicator on the device should stop blinking and turn solid, indicating a successful connection.
Automatic setup via AirPrint
Technology AirPrint, developed by Apple, allows you to print without installing additional drivers. This is the preferred method, as it ensures maximum compatibility and stability in the macOS environment. If your printer supports this feature, the system will automatically find it on the local network.
To start the process, open the Apple menu (the apple icon in the upper left corner) and select "System Preferences" (or "System Preferences" in older versions of macOS). In the window that opens, find the "Printers & Scanners" section. The system will automatically begin searching for available devices on the network.
- 🖨️ Click the "Add a printer, scanner, or fax" button (or just the plus "+" in the list of devices).
- 📡 In the list that appears, select your device. It should say "Secure AirPrint" or just "AirPrint" next to its name.
- ⚙️ In the "Use" field, the system will automatically select the appropriate driver. Make sure "Generic PostScript" is not selected if you have the option to select a specific model.
- ✅ Click "Add" to complete the installation.
After adding, it is recommended to print a test page. Open any document, click Command + P and select the newly installed printer. If the document prints, the setup was successful. If an error occurs, check to see if the printer is in "Paused" status.
Manual installation of drivers and manufacturer software
Not all manufacturers support the AirPrint protocol, especially budget or older models. In these cases, proprietary software is required. Drivers provide access to advanced features, such as duplex printing, tray customization, and ink level monitoring.
Download the installation package from the manufacturer's official website (HP, Canon, Epson, Brother). Avoid using third-party driver websites, as they may contain malicious code or incorrect software versions. During installation, follow the steps carefully: some installers require you to first connect the printer via USB cable for the initial Wi-Fi setup, and then disconnect the cable.
| Manufacturer | Name of the utility | Installation Features |
|---|---|---|
| HP | HP Smart / HP Easy Start | Requires HP account creation for full access |
| Canon | Canon IJ Network Tool | Allows you to change the IP address and port settings manually |
| Epson | Epson Software Updater | Automatically detects and updates printer firmware |
| Brother | Brother iPrint&Scan | Often requires manual port selection when connecting to a network. |
During the installation process, the wizard may prompt you to select a connection type. Select "Wireless" or "Network." The program will attempt to find the device. If the search is unsuccessful, select the "Specify printer by IP address" option. You can find the printer's IP address by printing a network configuration report (usually using a button combination on the device itself).
⚠️ Attention: Installer interfaces and menu item names may vary depending on the macOS version and driver release year. Always check the manufacturer's website for the latest documentation, as companies frequently update their software.
☑️ Check before installing the driver
Setting up a printer by IP address
Adding by IP address is the most reliable method when automatic discovery fails. It allows you to bypass issues with discovery protocols (Bonjour) and directly access the device on the network. This method is often necessary in corporate networks or when using complex routers.
First, find out the printer's IP address. This can be done through the device's menu or by printing a configuration report. The address usually looks like this: 192.168.1.XX. Then in the "Printers and Scanners" menu iMac Click the add new device button and go to the IP tab (globe icon).
In the window that opens, fill in the following fields:
- 🌐 Address: Enter the printer's IP address.
- 🔌 Protocol: select AirPrint (if supported) or HP Jetdirect - Socket (universal option for most laser printers).
- 🏷️ Name: Give it a descriptive name, such as "Office Laser."
After entering the information, the system will attempt to connect to the device. If the protocol is selected correctly, the driver will automatically be added to the "Use" field. If the system prompts you for "Printer Software," click the drop-down list and manually select your model from the macOS database. Click "Add," and your printer will appear in the list.
What to do if the IP address is dynamic?
If the router assigns a new IP address to the printer after a reboot, printing will stop working. To avoid this, go to the router settings and assign a static IP address to your printer's MAC address (DHCP Reservation).
Troubleshooting and diagnostics
Even with proper setup, issues may still occur. A common problem is the "Printer not responding" status. First, check to see if the printer has gone into sleep mode. Press the power button or any function button on the device to wake it up. Also, make sure AP Isolation isn't enabled on your router, which prevents devices on the Wi-Fi network from seeing each other.
If your drivers crash after updating macOS, try clearing the print queue and resetting the printing system. To do this, right-click (or Ctrl+click) an empty area of the printer list in the "Printers & Scanners" menu and select "Reset Printing System." Attention: This will remove all printers and scanners, they will have to be added again.
For a thorough diagnosis, use the built-in utility. Open Activity Monitor (via Spotlight) Command + Space and enter the name). From the Window menu, select Network and find the process related to printing (e.g. cups). However, for the average user, it will be more effective to use console commands to reset the print service.
sudo launchctl stop org.cups.cupsd
sudo launchctl start org.cups.cupsd
This command restarts the macOS print service, which often resolves the issue of jobs stuck in the queue. Enter your administrator password when prompted (characters won't display as you type).
Frequently Asked Questions (FAQ)
Why can't my iMac see my printer on my Wi-Fi network?
Most likely, the devices are on different subnets or frequencies (2.4 GHz vs. 5 GHz). Also, check if the macOS firewall is blocking the connection. Make sure the Wi-Fi light on the printer is lit and not blinking.
Is it possible to connect a printer without drivers?
Yes, if your device supports AirPrint. In this case, macOS uses built-in profiles. However, to access advanced features (double-sided printing, ink levels), it's recommended to install the manufacturer's software.
How to find the IP address of a printer if there is no screen?
Print a network configuration report. This is usually done by long-pressing the wireless button or by pressing the "Cancel" + "Wireless" button combination. You can also see the IP address in the list of connected clients in your router's interface.
Does Wi-Fi Direct printing work on iMac?
Wi-Fi Direct connections on macOS are unstable or don't work at all, as the Mac requires a connection to the main network to transfer data. It's best to use infrastructure mode (via a router) or a USB cable if a router isn't available.
