In this Guide we will cover how to make your network printer AirPrint compatible using a Raspberry Pi. This will allow you to print directly from your Apple iDevice to your existing non-airprint compatible printer. In this guide I will focus on the steps for a printer that is already networked. In our case a WiFi enabled Brother MFC printer. We will write another guide for USB printers.

You will need:

  1. Raspberry pi 3 wired to your LAN/network
  2. A SD card as the hard drive for your pi
  3. Raspbian Stretch with desktop installed on your SD card

Step 1:
To start off we need to update the software on the Raspberry Pi.  Run the following command to check for updates.
sudo apt-get update

Step 2:
Now we need to ensure the kernel is current.  Run the following command to check for updates to the kernel.
sudo apt-get upgrade

Step 3:
Now we need to install some new packages to enable the system to function as a CUPS server.
sudo apt-get install cups python-cups

Step 4 (Optional):
If you want to be able to print from windows devices install samba with the following command.
sudo apt-get install samba

Step 5 (Optional):
If you want a PDF printer run the following command.
sudo apt-get install cups-pdf

Step 6 (Optional):
If you have a HP printer get the HP printer drivers by running.
sudo apt-get install hplip

Step 7:
Now in the the browser on the Raspberry Pi desktop go to

Step 8:
Click the Administration tab.

Step 9:
Click Add Printer.
Sign in with the username “pi” and the password “raspberry”.
Next, for most networked printers you will choose “AppSocket/HP JetDirect” & Click Continue.

Step 10:
Enter “socket://192.168.1.x:9100” where the IP is the IP address of your printer.  9100 is the standard port for networked printers.
Click Continue.

Step 11:
Enter a Name for the printer, a Description, and a location note.
Make sure to check the “Share Printer” box during the setup. If you don’t do this you won’t see your printer.
Click Continue.

Step 12:
Select the make of your printer.  In my case I already installed the brother CUPS printer driver.  This is why Brother in my list.
Click Continue.

Step 13:
Choose your printer driver from the list and click “Add Printer”

Step 14:
Set the default printing options for your printer and click “Set Default Options”
Most likely you will need to change the Paper/Media Size from A4 to Letter.

Step 15:
You will now find yourself on the printers tab of the CUPS site.  The setup is complete.

Step 16:
Install Bonjour for AirPrint
sudo apt-get install avahi-discover

Step 17:
Reboot the Raspberry Pi.
sudo reboot

Step 18: Testing
If all has gone well you should now be able to open your iDevice and go to the icon of the box with the arrow pointing up.

Now select the printer Icon.

Next click the Select printer text in the printer options window.

Now you should be able to choose your printer from the list below.

If you don’t see your printer listed.
Confirm your printer is shared in the CUPS setup.

On my system after I would save settings changes to the CUPS admin, the CUPS service would not restart and I would get an error page. I ran the following command to restart CUPS.
sudo /etc/init.d/cups restart

How to restart avahi-discover.
sudo /etc/init.d/avahi-daemon restart

If you can’t login to the password prompt for CUPS, run the following command.  This will add the user pi to the group of users that can admin CUPS.  The default password for the “pi” user is “raspberry”.
sudo usermod -a -G lpadmin pi
