The installation of the printer driver in Linux Mint 17 or Ubuntu 14.04 was surprisingly easy, although it for this device (still?) Not "Driver Install Tool" are. Does not matter, because everything is described in detail on the support site. It is important to advance to look at the support page of the MFC-9142CDN Brother in which packages must be installed in advance, so that the driver can be set up clean.
The printed image is excellent, the printer has an acceptable volume development.
Was important to me also that it is possible to send scans directly from the device to a specified folder of my Synology NAS. Also it works via CIFS NTLMv2 with no problems. The whole is also in the web interface - there "Scan" menu - set. It is important that the destination folder in the beginning to be and / or entered without \. Does the folder where your scanned documents to land, eg scans, may also be only scans in the destination folder.
Since I am a customer of cable Germany, where "only" have VOIP, I was previously not sure if it works with the fax at all. But even that is no problem: Simply plug the included Brother TAE cable Brother MFC-9142CDN in the "Line" jack and the other end (with the "beard) laterally FON1 connect with the Fritz box 6360 is already possible to. fax.
This is the first device that I have from Brother. And I'm really excited about how easy it is made here to the (Linux) users. Strong buy recommendation!
