I have the equipment now in use within 1 week.
The establishment of the WLAN / LAN is not a problem, you can either configure the device on the screen or directly on a PC via the included software. Experienced users I recommend to refrain from installing the software, simply taking too much useless. Just install the driver and assign the IP and the thing runs.
Installation on Mac OS X, Windows XP and Windows 7 worked without problems.
The settings for the fax can be made directly on the device (or optionally also on the PC using the software), you can actually nothing wrong. Just the phone cord in and the thing runs.
The printing speed and quality are very good. From the speed I'm impressed, did not expect that it can go so fast ... The function Scan-to-USB is great, you can choose between PDF or JPG.
I can only recommend the device, just a perfect all-rounder ...
