I searched high and low to find instructions on how to print to my trusty AirPort Extreme wireless print server via Ubuntu linux, and came up relatively empty. I found instructions on how to set it up under Windows — obsolete instructions, as Apple actually makes an excellent utility for Windows that uses Bonjour — but nothing specific to linux. So here we go, using Ubuntu/Gnome:

1. Select “Printing” under the Administrative settings menu; authenticate.
2. Select “Network Printer”.
3. Select HP JetDirect printing.
4. Set the Host as the IP of the Airport router (probably 10.0.1.1).
5. Here’s the tricky part — all the instructions I found said to use port 9100, but this didn’t work for me. I port scanned the Airport router and got this:
   

   Port Scan has started ...

   Port Scanning host: 10.0.1.1

   Open TCP Port: 53 domain
Open TCP Port: 5009
Open TCP Port: 9101 bacula-dir
Open TCP Port: 10000 ndmp
Port Scan has completed ...

   …so I instead entered the printer port as 9101*.

6. I continued on to enter the make and model of the USB printer attached to the AirPort and successfully printed an Ubuntu test page — a lovely test page, by the way, puts other printer test pages to shame.
