My setup is a mac mini running OSX 10.8.2.
The setup procedure is very simple.
1. Download and install the drivers from http://www.dell.com/support/drivers/us/en/19/DriverDetails?driverId=9CRK3. During the install process change the printer network settings to your wifi network's settings.
2. Go to Apple Menu>System Preferences then click on the Print and Scan Icon. Click on the 'plus' button, and select 'Dell B1160w Mono Laser Printer.'
You can now print a test from textedit.
It has support for wirelessly printing from a mobile device, but I haven't tried it yet.
I plan to use this printer to home print shipping labels for the arduino ph shields that I sell.
