How to Double Side Print on Mac: A Comprehensive Guide

Double-sided printing, also known as duplex printing, is a fantastic way to save paper and reduce your environmental footprint. It’s a standard feature on most modern printers, and macOS is designed to support it seamlessly. However, many Mac users encounter frustrating situations where the double-sided printing option seems to disappear or is simply greyed out. If you’re struggling to figure out how to double side print on your Mac, you’ve come to the right place.

This guide will walk you through various methods to enable and troubleshoot double-sided printing on your macOS device. We’ll cover everything from basic setting adjustments to more advanced solutions, ensuring you can efficiently print on both sides of the paper.

Understanding Why Double-Sided Printing Might Not Work

Before diving into solutions, it’s helpful to understand why you might be facing issues with double-sided printing on your Mac. Several factors can contribute to this problem:

Printer Compatibility

The most fundamental requirement is that your printer must actually support duplex printing. While most newer printers do, older models might lack this feature. Always check your printer’s specifications on the manufacturer’s website or in the product manual to confirm if it’s capable of double-sided printing.

Driver Issues: The Role of AirPrint vs. Vendor Drivers

macOS offers two primary ways to connect and use printers: AirPrint and vendor-specific drivers.

AirPrint: This is Apple’s built-in technology that allows you to print wirelessly to compatible printers without installing drivers. While convenient, AirPrint drivers sometimes offer limited features compared to full vendor drivers. In some cases, using AirPrint might restrict access to duplex printing options.
Vendor-Specific Drivers: Printer manufacturers like HP, Epson, Brother, and Canon provide their own drivers, which are usually more comprehensive and unlock all the features of your printer, including advanced options like duplex printing. Using the correct vendor driver is often crucial for enabling double-sided printing reliably.

Software-Specific Problems

Occasionally, the issue might not be with your printer or driver but with the application you’re using to print. Some applications, particularly older software or certain PDF readers like Adobe Acrobat, might have their own print dialogs that don’t fully integrate with macOS’s printing features. This can sometimes lead to the double-sided printing option being hidden or unavailable within those specific programs.

Troubleshooting Steps to Enable Double-Sided Printing on Mac

Now that we understand the potential culprits, let’s explore various troubleshooting methods to get double-sided printing working on your Mac.

Method 1: Resetting the Printing System

This is a surprisingly effective first step suggested by users in online forums. Resetting the printing system can clear out any corrupted settings or driver conflicts that might be causing the issue.

Go to System Preferences.

System Preferences icon on macOS
Click on Printers & Scanners.

Printers and Scanners in System Preferences on macOS
In the left sidebar, hover over your printer’s name, right-click (or Control-click), and select “Reset printing system…”.

Reset printing system option on macOS
You’ll be prompted to confirm the reset. Click “Reset”.
After resetting, click the “+” button at the bottom of the printers list to add your printer back.
Crucially, in the “Add Printer” dialog, pay attention to the “Use” field. Instead of letting macOS automatically select “Secure AirPrint” or a similar default, click on the “Use” dropdown menu.

Use dropdown menu in Add Printer dialog on macOS
Select the original software/driver for your printer. This will likely be listed by your printer’s brand name (e.g., “Epson”, “HP”, “Brother”). You might see multiple options; try selecting the one that explicitly mentions “driver” or is specific to your printer model. Experiment with different options if necessary until you find one that offers duplex settings.
Click “Add”.
After adding the printer, you might see a window with “Installable Options”. Ensure that “Duplex Unit” or a similar option related to double-sided printing is checked. If you don’t see this during setup, don’t worry; we’ll check printer options later.

Use dropdown menu in Add Printer dialog on macOS
Try printing a document and check if the double-sided printing option is now available in the print dialog.

Method 2: Checking Printer Options & Supplies

Even with the correct driver installed, the duplex printing feature might need to be explicitly enabled in your printer’s settings within macOS.

Go back to System Preferences > Printers & Scanners.
Select your printer in the left sidebar.
Click on “Options & Supplies…”.
In the “Options & Supplies” window, click on the “Options” tab.
Look for settings related to “Duplex Unit” or “Two-Sided Printing”. The exact wording may vary depending on your printer model and driver.
Make sure the duplex option is enabled or “Installed”. If it’s set to “Not Installed” or unchecked, enable it and click “OK”.

Try printing again to see if double-sided printing is now working.

Method 3: Using CUPS Interface (Advanced)

For more advanced users, macOS uses CUPS (Common Unix Printing System) as its underlying printing system. CUPS has a web interface that allows for deeper printer configuration, including explicitly enabling duplex printing.

Enable the CUPS web interface. Open Terminal (Applications > Utilities > Terminal) and type the following command, then press Enter:
```
sudo cupsctl WebInterface=yes
```
You’ll be prompted for your administrator password. Enter it and press Enter.
Access the CUPS web interface. Open your web browser and go to http://localhost:631.
Click on the “Printers” tab.
Select your printer from the list.
In the printer administration area, you should see dropdown menus or buttons. Look for “Administration” and then “Set Default Options”. The exact labels might vary slightly depending on your printer driver.
Within the printer options, look for settings related to “Duplex”, “Two-Sided Printing”, or “Duplex Unit”.
Ensure that the duplex unit is set to “Installed” or “On”. It might be represented as a dropdown with options like “Installed/Not Installed” or checkboxes.
Click “Set Default Options” to save the changes. You might be asked to authenticate with your macOS username and password again.
Disable the CUPS web interface (for security). In Terminal, type:
```
sudo cupsctl WebInterface=no
```
Test printing to see if duplex printing is now enabled system-wide.

Method 4: Printer Webpage Settings (Epson Example)

Some printer manufacturers, like Epson as shown in the original forum thread, provide a web interface directly through the printer’s IP address. This interface often allows you to configure printer settings, including error handling which can sometimes affect duplex printing availability.

Find your printer’s IP address. You can usually find this in your printer’s network settings menu on its control panel, or sometimes through printer utility software on your Mac.
Enter the printer’s IP address into your web browser’s address bar. This should open your printer’s web interface.
Navigate through the web interface menus. Look for sections like “Advanced Settings”, “Printer Settings”, or “Configuration”. The menu structure will vary by printer brand and model.
Within the settings, look for options related to “Error Settings” or “Auto Error Solver”. In the Epson example provided in the forum, enabling “Auto Error Solver” was the solution.
Enable the relevant error setting if you find it.
Save any changes in the printer’s web interface.
Try printing from your Mac to see if double-sided printing is now available.

Common Scenarios and Solutions

Let’s address some specific scenarios that users often encounter:

Double-Sided Option Greyed Out

If the “Two-Sided” or “Duplex” option appears in the print dialog but is greyed out and unselectable, it usually indicates that macOS or the application doesn’t detect duplex capability for the currently selected printer driver.

Solution: The most common fix is to ensure you are using the correct vendor-specific driver as outlined in Method 1 (Resetting the Printing System). Avoid using generic AirPrint drivers if possible. Resetting the printing system and re-adding the printer with the correct driver is often the key.

Double-Sided Printing Not Working in Specific Apps (e.g., Adobe Acrobat)

As mentioned earlier, some applications might have their own print dialogs that can sometimes interfere with macOS’s printing features. Adobe Acrobat is a common example where users report issues with duplex printing options.

Solution 1: Check Application-Specific Print Settings: Within Adobe Acrobat’s print dialog, look for a “Printer…” button (as mentioned in the forum thread screenshot). Clicking this might open the standard macOS print dialog, where you should have access to the double-sided printing options.

(Replace image_url_placeholder_adobe_printer_button with an image URL if you have one showing this button)
Solution 2: Print as PDF and then Print from Preview: As a workaround, try “printing” your document to a PDF file (using the “Save as PDF” option in the print dialog). Then, open the PDF in macOS Preview application. Preview typically offers more reliable access to macOS’s standard print options, including double-sided printing. Print from Preview and see if the duplex option is available there.

Conclusion

Enabling double-sided printing on your Mac should be a straightforward process, but driver issues and configuration glitches can sometimes get in the way. By following the troubleshooting steps outlined in this guide, from resetting the printing system to exploring advanced CUPS settings and printer web interfaces, you should be able to resolve most double-sided printing problems.

Remember to always start by confirming your printer’s duplex capabilities and ensuring you’re using the correct vendor-provided drivers. By systematically working through these solutions, you’ll be well on your way to saving paper and enjoying efficient double-sided printing on your Mac.
